NERVOUS SYSTEM

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
A neuron that connects the central nervous system and a muscle is called:
A
A motor neuron
B
A relay neuron
C
A sensory neuron
D
The spinal cord
Explanation: 

Detailed explanation-1: -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.

Detailed explanation-2: -Motor neurons are also called efferent neurons.

Detailed explanation-3: -Motor neurons (MNs) are neuronal cells located in the central nervous system (CNS) controlling a variety of downstream targets. There are two main types of MNs, (i) upper MNs that originate from the cerebral cortex and (ii) lower MNs that are located in the brainstem and spinal cord.

Detailed explanation-4: -Motor neurones are cells in the brain and spinal cord that allow us to move, speak, swallow and breathe by sending commands from the brain to the muscles that carry out these functions. Their nerve fibers are the longest in the body, a single axon can stretch from the base of the spinal cord all the way to the toes.
