2.83 recall that the central nervous system consists of the brain and spinal cord and is linked to sense organs by nerves

Notes


The CNS consists of:
a) the brain
b) the spinal cord

The sensory organs (receptors) send nerve impulses through the CNS to the effector organs (effectors) by means of nerves. A nerve consists of neurones (nerve cells, essentially) amongst other things.
