Detailed explanation-1: -Neurons carry messages from the brain via the spinal cord. The neurons that carry these messages to the muscles are called motor neurons. Each motor neuron ending sits very close to a muscle fibre.
Detailed explanation-2: -Motor nerves carry messages from brain to muscles.
Detailed explanation-3: -Motor neurons carry instructions from the brain along axons that stretch from the spinal cord to the muscles in the hands and feet. In diseases eg spinal muscular atrophy, motor neuron axons become damaged and degenerate, which means signals from the brain never reach the muscles and movement becomes impaired.
