"the somatic and autonomic nervous systems are the two major divisions of the nervous system."

Answer;

-Peripheral nervous system

-The somatic and autonomic nervous systems are the two major divisions of the peripheral nervous system.

Explanation;

-The nervous system can be divided into two major subdivisions: the central nervous system (CNS) and the peripheral nervous system (PNS). The peripheral nervous system is comprised of the somatic and autonomic nervous systems. The somatic nervous system transmits sensory and motor signals to and from the central nervous system.

-The somatic nervous system is involved in the relay of sensory and motor information to and from the CNS; therefore, it consists of motor neurons and sensory neurons. Motor neurons, carrying instructions from the CNS to the muscles, are efferent fibers.

-The autonomic nervous system controls our internal organs and glands and is generally considered to be outside the realm of voluntary control. It can be further subdivided into the sympathetic and parasympathetic division.
