Nervous tissues are made of cells specialized to receive and transmit electrical impulses from specific areas of the body and to send them to specific locations in the body organized into structures called nerves. The structure of those three muscle tissue is described from its detail level according to the muscle fibers. 33.2D: Muscle Tissues and Nervous Tissues, [ "article:topic", "authorname:boundless", "showtoc:no" ], https://bio.libretexts.org/@app/auth/3/login?returnto=https%3A%2F%2Fbio.libretexts.org%2FBookshelves%2FIntroductory_and_General_Biology%2FBook%253A_General_Biology_(Boundless)%2F33%253A_The_Animal_Body%253A_Basic_Form_and_Function%2F33.2%253A__Animal_Primary_Tissues%2F33.2D%253A_Muscle_Tissues_and_Nervous_Tissues, 33.2C: Connective Tissues: Bone, Adipose, and Blood, http://cnx.org/content/m44731/latest...ol11448/latest, http://cnx.org/content/m44731/latest...e_33_02_03.jpg, http://cnx.org/content/m44731/latest...33_02_01ab.jpg, http://cnx.org/content/m44731/latest...e_33_02_02.jpg, http://cnx.org/content/m44731/latest...e_33_02_04.png, http://cnx.org/content/m44731/latest...e_33_02_06.jpg, http://cnx.org/content/m44731/latest...e_33_02_07.jpg, http://cnx.org/content/m44731/latest...e_33_02_10.jpg, http://cnx.org/content/m44731/latest...e_33_02_11.jpg, http://cnx.org/content/m44731/latest...e_33_02_09.jpg, http://cnx.org/content/m44731/latest...3_02_12abc.jpg, http://cnx.org/content/m44731/latest...e_33_02_13.jpg, Describe the structure and function of nervous tissue; differentiate among the types of muscle tissue. Nervous tissue is composed of neurons and supporting cells called neuroglia, or ” glial cells.” There are six types of neuroglia. CC LICENSED CONTENT, SPECIFIC ATTRIBUTION. Learning Objectives. https://www.differencebetween.com/difference-between-tissue-and-vs-cell Smooth muscle cells, spindle shaped with only one nucleus, contract involuntarily to push food through the digestive tract and blood through blood vessels. Tissues - Epithelium, Muscle, Connective Tissue and Nervous Tissue (Histology) Tissues are groups of cells with a common structure (form) and function (job). Simple columnar. They differ by the presence or absence of striations or bands, the number and location of nuclei, whether they are voluntarily or involuntarily controlled, and their location within the body. Nervous tissue makes up the peripheral and the central nervous system. Like in any other cell, the cell body is responsible for controlling metabolic activities. Vascular tissue transports water, minerals, and sugars to different parts of the plant. Connective Tissue Associated with Muscle Tissue Quiz: Connective Tissue Associated with Muscle Tissue Structure of Skeletal Muscle Quiz: Structure of Skeletal Muscle Muscle Contraction Types of Muscles There are four basic tissue types defined by their morphology and function: epithelial tissue, connective tissue, muscle tissue, and nervous tissue. Muscle tissue is made of "excitable" cells that are capable of contraction. Also Read: Muscular Tissue. It powers the neuron by synthes… On the contrary, a tissue has four known types: epithelial tissue, nerve tissue, muscle tissue, and connective tissue. Muscle tissue contracts forcefully when excited, providing movement. Watch the recordings here on Youtube! It contains a network of membrane called the sarcoplasmic reticulum. A muscle is a tissue that performs different functions which cause some sort of movement to take place. We also acknowledge previous National Science Foundation support under grant numbers 1246120, 1525057, and 1413739. It contains two types of cells - neurons and supporting cells. Skeletal muscle cells can contract by the attachment of myosin to actin filaments in the muscle, which then ratchets the actin filaments toward the center of the cells. The different types of connective tissue include adipose, fibrous, and elastic tissues as well as blood, bone, and cartilage. Muscle and nervous tissues are sometimes called composite tissues because they contain small amounts of areolar tissue along with their own muscle or nerve cells. Each cell is spindle shaped with a single nucleus and no visible striations (Figure 4.4.1 – Muscle Tissue). It has a large number of macrophages and fibroblasts, but it also has elastic and reticular fibers, as well as collagen. Like electrical circuits, the nervous system transmits signals … The function of muscle tissue (smooth, skeletal, and cardiac) is to contract, while nervous tissue is responsible for communication. Muscular tissue is the third of the four major categories of animal tissue. The branches join at special cellular junctions called "intercalated discs.". Tissue in the central nervous system can be found in the brain and spinal chord. There are four main tissues in the body – epithelium, muscle, connective tissue and nervous tissue. 1) Identify the four basic tissue types.-Epithelial-Muscle-Connective-Nervous 2) Explain the difference between simple and stratified tissues.Simple: one cell layer thick Stratified: multiple cell layers 3) Which tissue type is specifically found in the Respiratory Tract? Xylem tissue transports water and nutrients from the roots to different parts of the plant, and also plays a role in structural support in the stem. The three types of muscle can be distinguished by both their locations and their microscopic features. Nervous tissue is the main component of the nervous organs - the brain, spinal cord and nerves - which regulate and control body functions. Cardiac muscle cells, found only in the heart, are striated and branching (with one nucleus); they are joined by intercalacted discs which allow the cells to synchronize the beating of the heart. The main cell of the nervous system is the neuron. Glial cells support the neurons. Its main components include: Neurons – These are the structural and functional unit of nervous system. Spindle shaped cells with central nuclei, no striations, cells arranged closely to form sheets. Each cardiac muscle cell is in contact with another three or four cardiac muscle cells. For more information contact us at info@libretexts.org or check out our status page at https://status.libretexts.org. Vascular tissue is made of two specialized conducting tissues: xylem and phloem. A nerve consists of a neuron and glial cells. Of all the different tissue types (muscle, epithelial, connective, and nervous), muscle tissue is the most abundant tissue in most animals, including in humans. This tissue is what makes up the body’s nervous system, which is split into the central nervous system and the peripheral nervous system. Nervous tissue is also excitable, allowing for the generation and propagation of electrochemical signals in the form of nerve impulses that communicate between different regions of the body (Figure 4.1.1). Muscular tissue is a specialized tissue in animals which applies forces to different parts of the body by contraction. 2. It is made up of thin and elongated cells called muscle fibers. Connective tissue is derived from the third germ layer, the mesoderm, which is the same source of origin of muscle tissue. October 17, 2013. Let us compare the two in terms of control, location, and function. Muscle tissue contains myocytes, which have completely different structure than neurons. Four are found in the central nervous system, while two are found in the peripheral nervous system. Muscle and nervous tissues are sometimes called composite tissues because they contain small amounts of areolar tissue along with their own muscle or nerve cells. Smooth muscle tissue, for example, lines the insides of some organs and skeletal muscular tissue is used for movement and for purposeful force. Contractions of smooth muscle move food through the digestive tracts and push blood through the blood vessels. There is a large structure with a central nucleus: the cell body (or soma) of the neuron. Have questions or comments? Inside the cytoplasm, granules (Nissl bodies), mitochondria, golgi complex, lysosomes, and other cell organelles are present. This line, an intercalated disc, assists in passing electrical impulses efficiently from one cell to the next while maintaining the strong connection between neighboring cardiac cells, allowing the cardiac muscle cells to synchronize the beating of the heart. Equipment: Microscopes and histological slides. October 23, 2013. Nervous tissue is found within the nervous system and is made up of unique specialized cells. The three types of muscle tissues are such as skeletal, smooth, and cardiac. The muscle fibers are spread through the muscle structures […] October 17, 2013. Cardiac muscle is not under voluntary control, but is influenced by the autonomic nervous system to speed up or slow down the heart beat. 4.In terms of developmental processes, cells undergo mitosis (cell division) or meiosis to replicate while tissues go through tissue repair, or wound healing, taking place in two key manners by regeneration and by fibrosis. Nervous tissue is comprised of nerves, which are comprised of neurons, that send and receive signals, and glial cells, which support the neurons. The tissue is capable of performing the simple task while organs are known for operating the complex one. Also please explain it's’ rather odd peculiarities. Constriction of smooth muscle occurs under involuntary, autonomic nervous control in response to local conditions in the tissues. Cardiac muscle is found only in the heart. It mainly comprises the nucleus and cytoplasm. Describe the structure and function of nervous tissue; differentiate among the types of muscle tissue. Unless otherwise noted, LibreTexts content is licensed by CC BY-NC-SA 3.0. Long, cylindrical, multinucleate cells with obvious striations. The key difference between connective tissue and muscle tissue is that the main function of connective tissue is to provide a connection between tissues, organs and other body parts while the main function of the muscle tissue is to carry out movements of the body.. A tissue is a group of cells which have a common structure and function in our body. Smooth muscle tissue is also called non-striated as it lacks the banded appearance of skeletal and cardiac muscle. Smooth muscle cells have a single, centrally-located nucleus and are spindle shaped. OpenStax College, Animal Primary Tissues. Skeletal muscle has striations across its cells caused by the arrangement of the contractile proteins, actin and myosin, that run throughout the muscle fiber. Cells make tissues and tissues make an organ, and different organs present in the body make an organ system. It develops from the ectoderm of the embryo. Missed the LibreFest? Nervous Tissue. Epithelial tissue, small blood vessels, space between muscle, lymphatic vessels and nerve fibers are some of those structures. Cells in epithelial tissue or epithelium (epithelia; plural) are arranged in continuous sheets, in either single or multiple layers. An added feature to cardiac muscle cells is a line that extends along the end of the cell as it abuts the next cardiac cell in the row. The major part of the cell enclosed by a plasma membrane is the cell body, also known as the soma. OpenStax College, Biology. Epithelia tissue forms boundaries between different environments, and nearly all substances must pass through the epithelium. It controls the movement of an organism. There are three types of muscle tissue: skeletal, cardiac and smooth. The heart is composed of a specific kind of muscle tissue known as cardiac muscle. Muscle and nervous tissues are both richly vascularized. Nervous tissue is composed of nerves containing neurons, specialized cells. Branching, striated, generally uninucleated cells. The function of muscle tissue (smooth, skeletal, and cardiac) is to contract, while nervous tissue is responsible for communication. I. EPITHELIUM (EPITHELIAL TISSUE) Epithelial tissue is a type of animal tissue, consisting of closely aggregated polyhedral cells connected firmly to one another in the form of cellular sheets that line the interior of hollow organs and cover the body surface.. Tissues are groups of cells with a common structure (form) and function (job). Nervous tissues:They are made of cells specialized to receive and transmit electrical impulses from specific areas of the body and to send them to specific locations in the body organized into structures called nerves. OpenStax College, Biology. Difference Between Epithelial and Connective Tissue Definition. In its role as an interface tissue, epithelium accomplishes many functions, including: Protection for the underlying tissues from radiation, desiccation, toxins, and physical trauma. Organization of Cells. The cardiac muscle cells are situated in the heart’s walls, striated in appearance, and involuntarily under control. Some of the glial cells are phagocytic, removing debris or damaged cells from the tissue. Muscle and nervous tissues are both richly vascularized. Skeletal muscle is under voluntary, somatic nervous system control and is found in the muscles that move bones. There are several different types of tissue that fall into the category of muscle tissue. It forms the contractile component of the digestive, urinary, and reproductive systems as well as the airways and blood vessels. There are three different types of muscle cells: skeletal, smooth, and cardiac. Muscle tissue is subdivided into three broad categories: skeletal muscle, cardiac muscle, and smooth muscle. isotonic- tension developed by the muscle remains almost constant while the muscle changes length isometric- the tension generated is not enough to exceed the resistance of the object … Legal. Stimulation of these cells by somatic motor neurons signals the cells to contract. The various muscles of our bodies serve as the engines or powerhouses of the body and are so constructed to provide speed and power. Age: 7th-12th Objectives: Students will be able to identify the fours basic body tissues, their characteristics and function. Skeletal muscle cells, long, striated, multinucleate cells under voluntary control, are responsible for the movement of skeletal muscles. As nouns the difference between tissue and muscle is that tissue is thin, woven, gauze-like fabric while muscle is (uncountable) a contractile form of tissue which animals use to effect movement. The cytoplasm in the muscle fibers is called sarcoplasm. What is the difference between skeletal and cardiac muscles? Also, muscle is … The answer to your question could fill a Histology textbook. Similar to skeletal muscle, it has cross striations in its cells, but cardiac muscle has a single, centrally-located nucleus; the muscle branches in many directions. All connective tissues are characterized by the presence of a matrix in addition to cells. Though the size of the organ is greater than the tissue and requires more energy to perform any function. Epithelial Tissue: Epithelial cells are … Cardiac muscle cells are located in the walls of the heart, appear striated, and are under involuntary control. The overlapping region in each cell forms finger-like extensions in the cell membrane.These structures are called as intercalated disks.The structure of the intercalated disk forms gap junctions and desmosomes between the two cells, allowing the passage of electrochemical signals between … A tissue is a group of cells, in close proximity, organized to perform one or more specific functions.. As verbs the difference between tissue and muscle is that tissue is to form tissue of; to interweave while muscle is to use force to make progress, especially physical force. Nervous Tissues. The LibreTexts libraries are Powered by MindTouch® and are supported by the Department of Education Open Textbook Pilot Project, the UC Davis Office of the Provost, the UC Davis Library, the California State University Affordable Learning Solutions Program, and Merlot. Skeletal muscle is found attached to bones. There are three types of muscle in animal bodies: smooth, skeletal, and cardiac. Other glial cells support the nutritional and waste requirements of the neuron. Epithelial Tissue: Epithelial tissue line the cavity and surfaces of organs and blood vessels throughout the animal body. Nervous tissue has two main functions: sensing stimuli and sending impulses to different parts of the body as a response. There are four main tissues in the body – epithelium, muscle, connective tissue and nervous tissue. The walls of blood vessels, the tubes of the digestive system, and the tubes of the reproductive systems are composed primarily of smooth muscle. Helps movement of the egg and embryo in … Projections from the cell body are either dendrites, specialized in receiving input, or a single axon, specialized in transmitting impulses. The components of connective tissue in this type of tissue are more or less equally divided. The 3 types of muscle tissue are cardiac, smooth, and skeletal. Astrocytes regulate the chemical environment of the nerve cell, while oligodendrocytes insulate the axon so the electrical nerve impulse is transferred more efficiently. Function: 1. Skeletal muscles are voluntary muscles; a person has complete control of their movement. Gomori’s one-step trichrome stain eliminated vagaries of differentiation inherent in multi-step methods, but fine connective tissue fibers are sometimes poorly stained. Tissues … Connective Tissue: Connective tissue supports, connects and separates different types of tissues and organs in the body. Skeletal vs Cardiac Muscle. These muscle cells are relatively long and have multiple nuclei along the edge of the cell. It possesses the ability to initiate and transmit the nerve impulse.
