motor neuron

A motor neuron is a type of nerve cell that transmits signals from the brain and spinal cord to muscles, causing them to move. It acts as a communication link, receiving instructions from the central nervous system and relaying them to various muscles in the body. This process allows for voluntary movements like walking and gripping, as well as involuntary actions such as reflexes. Motor neurons are essential for coordinating muscle activity and enabling us to interact with our environment effectively. They form a vital part of the nervous system's control over physical motion.
