MUSCLE PHYSIOLOGY

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. Where they sit together is called a neuromuscular junction.

Detailed explanation-2: -The transfer of information from neuron to neuron takes place through the release of chemical substances into the space between the axon and the dendrites. These chemicals are called neurotransmitters, and the process is called neurotransmission.

Detailed explanation-3: -Motor neurons control voluntary muscle activity, such as walking and talking, and carry messages from nerve cells in the brain to the muscles.

Detailed explanation-4: -These impulses are transmitted to the brain through the interneurons of the spinal cord. Finally, response signals generated in the motor areas of the brain travel down the spinal cord through other interneurons and move to the body in the axons of spinal motor neurons.
