Question 4

Afferent and Efferent?

Answer 4

Afferent: (Sensory) neurons, takes sense information from the body to the CNS.

Efferent: (Motor) neurons, takes motor information from the CNS to the rest of the body.

Question 5

Autonomic Nerves?

Answer 5

Stimulate the Autonomic Nervous System (ANS).

Question 6
