Cell body nerve fibres known
as the axon.

3) It moves through the spinal cord at
133 metres per second. 4) After the sig-

moves in the opposite direction to the
medulla oblongata in the brain. 6)
From here it moves to the thalamus
and reaches the sensory cortex, its
final destination. All these processes
happen in less time than it takes you
