MCQ IN MEDICINE

Detailed explanation-1: -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-2: -The corticospinal tract provides voluntary control over skeletal muscles. This system begins in the pyramidal cells of the primary motor cortex, and the axons of these upper motor neurons descend into the brain stem and spinal cord to synapse on lower motor neurons, depicted in red, that control skeletal muscles.

Detailed explanation-3: -A somatic reflex is an involuntary response to a stimulus, such as pulling one’s hand away after touching a hot stove. The nervous system is split into the central nervous system (i.e., the brain and spinal cord) and the peripheral nervous system (i.e., nervous system outside of the brain and spinal cord).

Detailed explanation-4: -Cerebellum: The cerebellum, also known as the little brain, is responsible for smooth, coordinated voluntary movements.
