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: -Afferent, or sensory, neurons carry impulses from peripheral sense receptors to the CNS. They usually have long dendrites and relatively short axons. 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: -Efferent neurons – also called motor neurons – are the nerves responsible for carrying signals away from the central nervous system in order to initiate an action.

Detailed explanation-3: -Motor or efferent neurons transmit impulses from the central nervous system towards the effectors (muscle or glands), while sensory neurons transmit impulses from the sense organs towards the central nervous system (brain and spinal cord).
