Detailed explanation-1: -The somatic peripheral nervous system is a single neuron system with the motor neurons lying inside the brainstem or spinal cord and the sensory neurons lying in the dorsal root ganglia. The autonomic peripheral nervous system is a two neuron system with a neuron lying outside of the CNS in the autonomic ganglia.

Detailed explanation-2: -The somatic motor division carries signals to the skeletal muscles. The visceral motor division, also known as the autonomic nervous system, carries signals to glands, cardiac muscle, and smooth muscle.

Detailed explanation-3: -The peripheral nervous system consists of the nerves that branch out from the brain and spinal cord. These nerves form the communication network between the CNS and the body parts. The peripheral nervous system is further subdivided into the somatic nervous system and the autonomic nervous system.

Detailed explanation-4: -Each neuron consists of the following: Cell body: This is the main part of the cell. It conducts and transmits signals throughout the various structures that extend outward from it. Axon: Each neuron has one axon, a long, arm-like extension that reaches outward from the cell body.

Detailed explanation-5: -Sympathetic nervous system: This system activates body processes that help you in times of need, especially times of stress or danger. Parasympathetic nervous system: This part of your autonomic nervous system does the opposite of your sympathetic nervous system. More items •15-Jun-2022
