Which neurons are involved in sending signals from the brain to muscles?

Motor neurons are responsible for transmitting signals from the brain and spinal cord to the muscles, facilitating motor control and movement. They carry commands from the central nervous system to the skeletal muscles, enabling voluntary activities such as walking, running, and fine motor skills. These neurons connect directly to muscle fibers, resulting in muscle contraction when the signal is received.

Sensory neurons, in contrast, transmit sensory information from the body to the central nervous system, providing feedback about the external environment and the body's state. Interneurons serve as connectors and processors within the central nervous system, communicating between sensory and motor neurons but do not directly send signals to muscles. Afferent neurons is another term generally associated with sensory neurons; they specifically carry signals toward the central nervous system instead of sending signals to muscles. Thus, motor neurons stand out as the key players in conveying the signals that initiate muscle movement.
