2.0 Tissues of the nervous system Listen

Nervous tissue is composed of relatively few cell types categorized into two groups:

  • nerve cells, often called neurones
  • glial cells

Nerve cells are the cells that transmit nerve impulses. They account for signal transmission from one part of the brain to another, or from the brain and spinal cord to other organs, muscles and glands. Glial cells support neurons.

  • Describe the characteristics of the nerve cell
  • Explain the types of glial cells found within the nervous system
  • Explain the main function of Schwann cells and ependymal cells
