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 autonomic nervous system (ANS) plays a fundamental role in maintaining cell homeostasis and human life. The functionality of the heart and skeletal muscles is partially modulated by sympathetic and parasympathetic branches of the ANS both in resting and exercising conditions.
Detailed explanation-3: -Motor neurons within the SNS, also known as efferent neurons, carry motor information from the CNS to muscle fibers throughout the body. These types of neurons transmit signals from the spinal cord and brainstem to skeletal and smooth muscle to either directly or indirectly control muscle movements.
Detailed explanation-4: -Answer and Explanation: The somatic nervous system is responsible for voluntary movements like a skeletal muscle contraction. Motor neurons are responsible for carrying neural signals from the central nervous system out to the effector which in this case would be a skeletal muscle fiber.
