The word Muscles refer to all contractile tissue. They are responsible for the computation and communication that the nervous system provides. Nervous or the nerve tissue is the main tissue of our nervous system. Most of the fibres within the grey matter are non-medullated. Coordinates, regulates, and integrates body functions. Muscular system - Types of muscles, characteristics & functions. General Characteristics of Nervous Tissue Function • transmit impulses for coordination, regulation, integration, & sensory reception Location • brain, spinal cord, nerves Characteristics • cells connect to each other & other body parts • Cells contain a single nuclei • Cells are called neurons • Highly branched Neurons are the basic unit of nervous tissue. The amount of matrix is more in connective tissue but the number of cells is comparatively less. This may be abundant in some tissues and minimal in others. 2. Nervous Tissue. Functional studies in vitro and genetic studies in mice have provided evidence that the extracellular matrix affects virtually all aspects of nervous system development and function. The special type of cell which forms the nerve tissue is called nerve cell or neuron (Figure). Let us have a glimpse of each type of animal tissue in detail. The animal tissues are divided into epithelial, connective, muscular and nervous tissues. Four are found in the central nervous system, while two are found in the peripheral nervous system. The pink lines that are attached to these neurons are their processes. Nervous Tissue. . Brain,spinal cord,nerves are made up of nervous tissue. They are multicellular with tissue grade of organization.

Movement: Our body's skeleton gives enough rigidity to our body that skeletal muscles can yank and pull on it, resulting in body movements such as walking, chewing, running, lifting, manipulating objects with our hands, and picking our noses. TISSUES Epithelial tissues Connective tissues Muscular tissues Nervous tissues 6. Sedentary or free-swimming. 2 Sketch and label the characteristics of muscle tissues and nervous tissues that you were able to observe. Nervous tissue contains two categories of cells-neurons and neuroglia. (about 150-200 words) Who are the experts? Types of Animal Tissue. Nervous tissue, found in the brain and spinal cord, contains specialized cells called neurons that conduct nerve impulses.A neuron (Fig. Describe the characteristics of nervous tissue Nervous tissue is characterized as being excitable and capable of sending and receiving electrochemical signals that provide the body with information. Nervous tissue is one of four major classes of tissues. Nervous tissue stimulates and transmits the stimulus very rapidly from one place to another within the body. Thus, they are encompassed within the set of neuroglial cells. The neurons carry electrical and chemical signals throughout the human body while the supportive cells provide nutrition to the neurons. Nervous tissue is composed of three main parts: nerves, the spinal cord and the brain. Nervous Tissue. For example, imagine a scenario in which you are attempting to hammer a nail into the wall. Save. The process of inflammation contains, neutralizes, or dilutes the injury-causing agent or lesion, regardless of tissue type [].In both the CNS and non-CNS, the tissue environment in which inflammation begins is a mixture of injured tissue, components of the clot (platelets, erythrocytes, and fibrin), extravasated serum proteins, and foreign material introduced at the . Nervous tissue falls into two different cell categories as well. Nervous tissue is one of four major classes of tissues. The Nervous tissue will be studied in more detail later on. Nervous system, organized group of cells specialized for the conduction of electrochemical stimuli from sensory receptors. This is the most common type o BIPOLAR have two extensions…one dendrite, one axon. They have a columnar morphology and . There are four basic tissue types defined by their morphology and function: epithelial tissue, connective tissue, muscle tissue, and nervous tissue. 3 Indicate a location and function of each type of muscle tissue and nervous tissue. It stimulates muscle contraction, creates an awareness of the environment, and plays a major role in emotions, memory, and reasoning.To do all these things, cells in nervous tissue need to be able to communicate with each other by way of . It consists of neurons and supporting cells called neuroglia. 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. The four basic types of tissue are epithelial tissue, connective tissue, muscle tissue, and nervous tissue. Muscle and Nervous Tissue DRAFT. Our nervous tissue allows us to experience stimuli and then make a response. They are responsible for the computation and communication that the nervous system provides. Learn about the nervous systems of different living organisms. Nervous tissue 100X Motor Neuron smear Each neuron (n) has extensions called processes (axons and dendrites) that allow it to communicate with other neurons. Nervous tissue is composed of neurons and supporting cells called neuroglia, or " glial cells.". Explain factors limit neurogenesis in the CNS of adults, why is it so hard to repair a damaged nerve? About 90% of the cells in the central nervous system--brain and spinal cord--are supporting cells (sc). Structural Characteristics: Connective tissue (CT) is one of the four basic types of animal tissue, along with epithelial tissue, muscle tissue, and nervous tissue.
