What is the purpose of the motor neuron?
to carry information from sense organs to the brain or spinal cord
to carry information from the brain or spinal cord to sense organs
to carry information from the brain or spinal cord to muscles and glands
to carry information from muscles and glands to the brain or spinal cord

The purpose of the motor neuron is to carry information from the brain or spinal cord to muscles and glands.

Option: C

Explanation:

A neuron whose cell body is situated in the motor cortex, brainstem or spinal cord and whose axon extends to the spinal cord or beyond the spinal cord to explicitly or implicitly control effector organs, primarily muscles and glands, thus understood as a motor neuron.

It is a part of the central nervous system (CNS) which bind across the body with muscles, glands and organs. Such neurons send impulses (like from stomach) from the spinal cord to skeletal and smooth muscles and therefore directly regulate all of our muscle contractions or motion.
