Motor neurons are responsible for what action?

Motor neurons play a crucial role in the nervous system by transmitting information from the brain to muscles and glands, which is essential for initiating movement and various bodily functions. When the brain decides to perform an action, motor neurons carry signals that instruct muscles to contract, leading to movements like walking or grasping, or they signal glands to release hormones or other substances.

This function is fundamental to the coordination of voluntary actions in response to stimuli, effectively translating neural impulses into physical activity. The other options pertain to different types of neurons: sensory neurons convey information from sensory receptors to the brain, while the choices about receiving and sending information to the brain do not accurately capture the specific role of motor neurons in the motor pathway.
