    Study Notes

    Nervous Tissue Overview

    • Composed of specialized nerve cells known as neurons.
    • Accompanied by neuroglial cells, which support neurons and ensure proper nervous system physiology.

    Function of Nerve Cells

    • Generate neuroglial cells.
    • Conduct electrical signals essential for communication within the nervous system.

    Role of Neuroglial Cells

    • Provide structural support by binding neurons together.
    • Perform diverse functions crucial for the normal operation of the nervous system.
    • Unlike neurons, they do not conduct nerve impulses.

    Neuron Structure

    • Comprised of three main parts:
      • Cell Body: Contains the nucleus, serving as the metabolic center.
      • Dendrites: Highly branched extensions that receive signals from other neurons or receptor cells.
      • Axon: A singular extension responsible for transmitting nerve impulses away from the cell body to other neurons or effector cells; can be several feet long.

    Locations of Nervous Tissue

    • Predominantly found in:
      • Brain
      • Spinal cord
      • Nerves

    Importance of the Cell Body

    • Central location for the nucleus.
    • Acts as the metabolic hub for the neuron, facilitating necessary biological processes.
