t collects inputs from other neurons (via the dendrites), processes them (in the cell body) and gives an output (via the axon)

your body there is a whole system of nerves that is not under your conscious control. This is known as the autonomic nervous system, and it regulates aspects such as breathing, intestinal contractions, the relaxation and constriction of blood vessels, sweating and hair standing on end.

most neurons the axon is coated with a fatty white sheath called ‘myelin’, which acts as a kind of insulator, speeding the transmission of nervous signals.

he central nervous system includes the brain and spinal cord, while the peripheral includes the nerves that extend to your skin and muscles, and which carry sensory and motor signals, or impulses.

neuron consists of a cell body with many ‘projections’ leading away from it. Most of these projections are ‘dendrites’, which collect information from other neurons and bring it to the cell body.
