Answer 2

CARRY nerve impulses from sensory receptors found in PERIPHERAL NS to the CNS

These RECEPTORS are found in the eyes, ears, tongue, skin

Some sensory nuerons carry INFO to the BRAIN from receptors which TRANSLATES the info into SENSATIONS.

Question 3

what do motor nuerons do?

Answer 3

begin in the CNS and send their AXONS outside the cns to CONTROL muscles and glands

Form SYNAPSES with muscles and control their CONTRACTIONS

When TRIGGERED, motor nuerons RELEASE nuerotransmitters that BIND to receptors on the muscle and trigger MOVEMENT.
