What is the function of motor neurons?

Motor neurons are specialized nerve cells that play a crucial role in the nervous system by conducting signals from the central nervous system (CNS) to effectors, such as muscles and glands. Their primary function is to transmit impulses away from the CNS, facilitating movement and actions in response to commands. When a motor neuron is activated, it sends an electrical signal that leads to muscle contraction or gland secretion, effectively allowing organisms to interact with and respond to their environment.

The other functions mentioned involve different types of neurons: sensory neurons send signals to the CNS from the body, while interneurons process these signals within the CNS. Motor neurons specifically function in the opposite direction, illustrating the flow of information that allows for coordinated movement and response. By focusing solely on sending signals away from the CNS, motor neurons are essential for enabling physical responses in both voluntary and involuntary actions.
