AP PSYCHOLOGY

Detailed explanation-1: -The somatic nervous system (SNS) and the autonomic nervous system (ANS) are both part of the peripheral nervous system. The SNS controls voluntary actions such as walking. The ANS is responsible for the control of vital functions such as heart beat and breathing.

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: -The radial nerve provides motor (movement) and sensory functions to the arm. It: Stimulates muscles so you can straighten and raise your elbows, wrists, hands and fingers.

Detailed explanation-4: -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-5: -The central nervous system (CNS) consists of the brain and spinal cord. The CNS controls the voluntary actions of the body, as well as some involuntary actions, such as reflexes.
