Detailed explanation-1: -Skeletal muscle contraction is voluntary and under the regulation of the somatic nervous system. Each skeletal muscle cell is innervated by a motoneuron, and each muscle fiber behaves as a single unit. Smooth muscle, on the other hand, is involuntary and under the regulation of the autonomic nervous system.

Detailed explanation-2: -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-3: -Your somatic nervous system allows you to move and control muscles throughout your body. It also feeds information from four of your senses-smell, sound, taste and touch-into your brain.

Detailed explanation-4: -Sensory neurons are activated by a stimulus, which is sent to the central nervous system, and a motor response is sent out to the skeletal muscles that control this movement.
