Question

This portion of the motor division of the nervous system conducts action potentials from the central nervous system to skeletal muscle fibers. Which option correctly identifies this portion?

1) Afferent
2) Autonomic
3) Somatic
4) Sympathetic

Answer 1

The somatic nervous system is the division of the motor division of the nervous system that directs action potentials from the CNS to skeletal muscles, allowing for voluntary movement.

Step-by-step explanation:

The portion of the motor division of the nervous system that conducts action potentials from the central nervous system to skeletal muscle fibers is known as the somatic nervous system. This division is responsible for our conscious perception of the environment and for voluntary responses to that perception, which include the movement of skeletal muscles. Motor neurons within the somatic nervous system are considered efferent fibers, meaning they carry signals "exiting" the central nervous system to stimulate muscle contractions.
