MICROANATOMY

Detailed explanation-1: -The peripheral nervous system is further subdivided into the somatic nervous system and the autonomic nervous system. The somatic nervous system consists of nerves that go to the skin and muscles and is involved in conscious activities.

Detailed explanation-2: -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-3: -The autonomic nervous system is a component of the peripheral nervous system that regulates involuntary physiologic processes including heart rate, blood pressure, respiration, digestion, and sexual arousal. It contains three anatomically distinct divisions: sympathetic, parasympathetic, and enteric.

Detailed explanation-4: -Your peripheral nervous system has two main subsystems: autonomic and somatic. Autonomic: These are nervous system processes your brain runs automatically and without you thinking about them. Somatic: These are functions you manage by thinking about them.

Detailed explanation-5: -Your somatic nervous system is a subdivision of your peripheral nervous system, which is all of your nervous system except your brain and spinal cord. Your somatic nervous system allows you to move and control muscles throughout your body.
