Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Neurons that transmit motor impulses from CNS to effectors are called:
A
afferent
B
efferent
C
sensory
D
interneurons
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: -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-3: -All motor neurons are efferent neurons as these neurons send signals from the central nervous system to effector organs like muscles or glands for responding to the stimulus and perform their function.

Detailed explanation-4: -Motor neurons of the spinal cord are part of the central nervous system (CNS) and connect to muscles, glands and organs throughout the body. These neurons transmit impulses from the spinal cord to skeletal and smooth muscles (such as those in your stomach), and so directly control all of our muscle movements.
