Nervous tissue is found in the brain, spinal cord, and nerves. It is responsible for coordinating and controlling many body activities. It stimulates muscle contraction, creates an awareness of the environment, and plays a major role in emotions, memory, and reasoning.
Nerve Tissue. Although the nervous system is very complex, there are only two main types of cells in nerve tissue. The actual nerve cell is the neuron. It is the conducting cell that transmits impulses and the structural unit of the nervous system. The other type of cell is neuroglia, or glial, cell.The word neuroglia means nerve glue.. These cells are nonconductive and provide a support system for the neurons. They are a special type of connective tissue for the nervous system.he unmyelinated regions between the myelin segments are called the nodes of Ranvier. In the peripheral nervous system, the myelin is produced by Schwann cells. The cytoplasm, nucleus, and outer cell membrane of the Schwann cell form a tight covering around the myelin and around the axon itself at the nodes of Ranvier.
