AP PSYCHOLOGY

Detailed explanation-1: -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-2: -Afferent messages carry sensations such as heat, cold, or pain. The first synapse (in the sympathetic chain) is mediated by nicotinic receptors physiologically activated by acetylcholine, and the target synapse is mediated by adrenergic receptors physiologically activated by either noradrenaline or adrenaline.

Detailed explanation-3: -Parts of the Somatic Nervous System Motor neurons, also known as efferent neurons, are responsible for carrying information from the brain and spinal cord to muscle fibers throughout the body.

Detailed explanation-4: -The peripheral nervous system is the network of nerves strands that branch off from the left and right sides of the spinal cord through openings between each vertebra on the spinal canal. These nerve pairs spread throughout your body to deliver commands from your brain and spinal cord to and from parts of your body.
