MEDICAL PHYSIOLOGY

Detailed explanation-1: -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-2: -Thalamus: The thalamus is the relay center of the brain. It receives afferent impulses from sensory receptors located throughout the body and processes the information for distribution to the appropriate cortical area. It is also responsible for regulating consciousness and sleep.

Detailed explanation-3: -Specifically, the somatic nervous system is responsible for movement of voluntary muscles and the process known as a reflex arc. This system carries nerve impulses back and forth between the central nervous system, which is the brain and the spinal cord, and the skeletal muscles, skin, and sensory organs.

Detailed explanation-4: -The sensory-somatic nervous system is composed of cranial and spinal nerves and contains both sensory and motor neurons. Sensory neurons transmit sensory information from the skin, skeletal muscle, and sensory organs to the central nervous system (CNS).
