Question

What is the purpose of the motor neuron?

Answer 1

To send information from the brain or spinal cord to muscles and glands - is the purpose of motor neuron

Explanation:

As part of the central nervous system (CNS), the motor neurons connect the brain and spinal cord to all the muscles and glands present all over the body and innervates them.

Their main function is to transmit nerve impulses from the CNS to the muscles, both skeletal and smooth, and directly controls the movements of the muscles of the body.

A motor neuron is a typical nerve cell with multipolar body. It can be upper of lower motor neuron.

Right from snapping of fingers to movements of hamstrings, all muscular movements functions due to impulse carried by the motor neurons.

Degeneration of the motor neurons leads to neurodegenerative diseases like spinal muscular atrophy or amyotrophic lateral sclerosis.

Answer 2

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.
