What role does the somatic nervous system play?
a. it transmits messages about sights, sounds, smells, and so on, to the central nervous system.
b. it converts messages that are received from the central nervous system into involuntary reflexes.
c. it commands the brain to filter unwanted neural impulses that have been accidentally triggered.
d. it primarily regulates the glands and the muscles of internal organs.

b. It converts messages that are received from the central nervous system into involuntary reflexes.

Explanation:

The somatic nervous system (SNS) is part of the peripheral nervous system (SNP), which is responsible for transmitting motor and sensory information both back and forth to the central nervous system (CNS).

The main function of the somatic nervous system is to connect the central nervous system to the organs, muscles and skin. This allows us to perform complex movements and behaviors. Somatic neurons carry messages from the external areas of the body that are directly related to the senses. The information captured by the sensory systems is transmitted to the central nervous system. The CNS then sends signals through the nervous networks of the somatic system to the muscles and organs.
