GROSS ANATOMY

Detailed explanation-1: -Your somatic nervous system is a subdivision of your peripheral nervous system that stretches throughout nearly every part of your body. The nerves in this system deliver information from your senses to your brain. They also carry commands from your brain to your muscles so you can move around.

Detailed explanation-2: -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-3: -The somatic nervous system is a component of the peripheral nervous system associated with the voluntary control of the body movements via the use of skeletal muscles.

Detailed explanation-4: -The somatic nervous system is under conscious control, meaning that we can choose to move our muscles or not. For example, when we decide to pick up a book, our brain sends signals down the motor neurons to our arm muscles, telling them to contract. The somatic nervous system can also undergo unconscious activation.

Detailed explanation-5: -In addition to regulating the voluntary movements of the body, the somatic nervous system is also responsible for a specific type of involuntary muscle responses known as reflexes, controlled by a neural pathway known as the reflex arc.
