Question

Motor nerves, such as ones that stimulate the arrector pili muscles, are also known as which type of nerve?

A) Sensory nerves
B) Autonomic nerves
C) Efferent nerves
D) Afferent nerves

Answer 1

Motor nerves, such as the ones that stimulate the arrector pili muscles, are known as efferent nerves, which carry signals from the central nervous system to muscles and glands.

Step-by-step explanation:

Motor nerves that stimulate structures like the arrector pili muscles are also known as efferent nerves. These nerves carry impulses from the central nervous system to muscles and glands, such as in the case of producing goose bumps when the arrector pili muscles contract. This type of nerve is distinct from sensory nerves or afferent nerves, which transmit information from sensory receptors back to the central nervous system.
