MEDICAL PHYSIOLOGY

Detailed explanation-1: -The peripheral nervous system is further subdivided into an afferent (sensory) division and an efferent (motor) division. The afferent or sensory division transmits impulses from peripheral organs to the CNS.

Detailed explanation-2: -The somatic nervous system is part of the efferent division of the PNS and is considered to be the voluntary branch. The axons of this system are called motor neurons and are used to innervate skeletal muscle. ACh is released from the motor neurons, and stimulates skeletal muscle, causing it to contract.

Detailed explanation-3: -Sensory neurons: Also called afferent neurons, sensory neurons carry information from the nerves to the central nervous system. The sensory neurons allow us to take in sensory information and send it to the brain and spinal cord.

Detailed explanation-4: -The Sensory Division They include sight, hearing, balance, touch, taste, and smell. We have special sense organs for each of these senses. What is the sense organ for sight?
