Question

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

Explanation:

Motor neurons are part of the nervous system. Sensory neurons carry info from sense organs to CNS (brain/spinal cord). Motor neurons transmit signals from CNS (brain or spinal cord) to effectors like muscles and glands to initiate responses. The first option is for sensory neurons (afferent), the second is incorrect as motor neurons don't target sense organs, the fourth is also sensory - like (afferent from effectors, but motor is efferent to effectors). So the correct one is the third option.

Answer:

C. to carry information from the brain or spinal cord to muscles and glands
