The motor/efferent division of the nervous system carries impulses from the CNS to
A
muscles and glands
B
muscles and bones
C
muscles and blood cells
D
glands and blood cells
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: -Efferent, or motor, neurons transmit impulses from the CNS to effector organs such as muscles and glands. Efferent neurons usually have short dendrites and long axons.

Detailed explanation-3: -The autonomic nervous system conducts impulses to cardiac muscle, smooth muscle, and skeletal muscle.

Detailed explanation-4: -The motor neurons carry impulses from the CNS to the effectors.

Detailed explanation-5: -The spinal cord is a vital aspect of the CNS found within the vertebral column. The purpose of the spinal cord is to send motor commands from the brain to the peripheral body as well as to relay sensory information from the sensory organs to the brain.
