Explanation: The muscles of the body are part of the musculoskeletal system of the body. The nervous system is essential to the functioning of the muscles because the nervous system provides the impulses that cause muscles to contract. Without the actions of the nervous system, the muscles would not operate.

Answer 2

The answer is nervous system.

Neurones are part of the nervous system. Impulses from the brain in the form of action potential travel from brain centres through the neurones. A contact between a neurone and a muscle fibre is called a neuromuscular junction. When an action potential reaches the end (presynaptic terminal) of a motor neurone, it will induce a release of neurotransmitters from the motor neurone. Neurotransmitters pass through the synaptic cleft and bind to the receptor on the muscle fibre which results in muscle contraction.
