Quizplus · Accepted Answer

Neurons are the basic unit of the brain and nervous system. They transmit information through electrical and chemical signals, allowing for communication within the nervous system and between the nervous system and other parts of the body. Nerves are bundles of axons (long extensions of neurons) that carry these signals between the brain, spinal cord, and other parts of the body. Astrocytes and glial cells are types of supporting cells in the nervous system.
