What is the main function of motor neurons?

The main function of motor neurons is to carry messages from the central nervous system (CNS) to effectors, such as muscles and glands. Motor neurons are essential in facilitating movement and responses, as they enable the brain and spinal cord to communicate with the peripheral muscles, leading to muscle contraction and the execution of voluntary movements. This allows for coordinated actions in response to stimuli.

While sensory neurons transmit information from sensory receptors to the CNS and play a crucial role in sensation, they are distinct from motor neurons. The connection between reflex actions and voluntary movements often involves both motor and sensory pathways, but the primary task of motor neurons is specifically to relay commands from the CNS to the body’s effectors. Additionally, certain support cells, known as glial cells, assist neurons but do not perform the direct functions of transmitting signals or messages.
