The motor division of the nervous system includes ____
A
afferent nerves
B
efferent nerves
Explanation: 

Detailed explanation-1: -The motor (efferent) division carries motor signals by way of efferent nerve fibers from the CNS to effectors (mainly glands and muscles). It can be further subdivided into somatic and visceral divisions. The somatic motor division carries signals to the skeletal muscles.

Detailed explanation-2: -The afferent or sensory division transmits impulses from peripheral organs to the CNS. The efferent or motor division transmits impulses from the CNS out to the peripheral organs to cause an effect or action.

Detailed explanation-3: -Efferent neurons, also called motor neurons, are the nerve fibers responsible for carrying signals from the brain to the peripheral nervous system in order to initiate an action. In other words, they are the neurons that tell your body to perform an action, such as removing your hand from a hot pan.

Detailed explanation-4: -The efferent nervous system is also called the motor nervous system because these neurons control the movement of the body. There are two main divisions of the efferent nervous system: The somatic nervous system. The autonomic nervous system.

Detailed explanation-5: -The somatic nervous system consists of both afferent (sensory) and efferent (motor) nerves [1].
