Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
In the PNS, ____ neurons take messages from the spinal cord to muscles.
A
Sensory
B
Motor
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -Motor neurons: Also called efferent neurons, motor neurons carry information from the brain and spinal cord to muscle fibers throughout the body. These motor neurons allow us to take physical action in response to stimuli in the environment.

Detailed explanation-2: -Motor neurons – also known as efferent neurons, they transmit signals from the CNS to skeletal and muscle to either directly or indirectly control muscle movements.

Detailed explanation-3: -The peripheral nervous system (PNS), which consists of the neurons and parts of neurons found outside of the CNS, includes sensory neurons and motor neurons. Sensory neurons bring signals into the CNS, and motor neurons carry signals out of the CNS.

Detailed explanation-4: -Overall, motor neurons (or motoneurons) comprise various tightly controlled, complex circuits throughout the body that allows for both voluntary and involuntary movements through the innervation of effector muscles and glands.

Detailed explanation-5: -Motor neurons 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.
