- Angelyn Evan Bomediano replied 3 years, 9 months ago
  Our bodies contain nerve tissue such as in our brains. It coordinates and controls several bodily functions. It induces muscle contraction, raises environmental awareness, and influences emotions, memory, and thinking. To perform all of this, nerve cells must be able to interact via electrical nerve impulses. Neurons are the cells in the nervous system that generate and conduct impulses. These cells have dendrites, a cell body, and an axon. The cell body is the major component of the cell that performs general activities. Dendrites are cytoplasmic extensions that transport impulses to the cell body. An axon sends impulses away from the cell body.
  
  Nervous tissue contains cells that do not transmit impulses but rather support neuronal activity. The neuroglia are glial cells (neuroglial cells). Glia cells bind and insulate neurons. Some phagocytize germs, while others bind blood arteries to neurons to deliver nutrients.

  1. Neurons vary considerably in size and form. Because human brains are so enormous, the smaller rat brain is explored here.
  2. On either side of the spinal cord, sympathetic ganglia form lengthy chains. They transmit information regarding danger, stress, and the fight-or-flight response.
  3. The spinal cord’s primary job is to transmit nerve messages between the brain and the rest of the body.
