Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Neurons that transmit impulses Away from the CNS are called
A
sensory, ventral
B
sensory, dorsal
C
motor, efferent
D
motor, dorsal
Explanation: 

Detailed explanation-1: -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-2: -Afferent neurons carry information from sensory receptors of the skin and other organs to the central nervous system (i.e., brain and spinal cord), whereas efferent neurons carry motor information away from the central nervous system to the muscles and glands of the body.

Detailed explanation-3: -A motor neuron (or motoneuron or efferent neuron) is a neuron whose cell body is located in the motor cortex, brainstem or the spinal cord, and whose axon (fiber) projects to the spinal cord or outside of the spinal cord to directly or indirectly control effector organs, mainly muscles and glands.

Detailed explanation-4: -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.
