Muscle Innervation

Antagonistic Muscle Pairs

stimulation of a muscle by an impulse transmitted by a motor nerve.

motor nerve enable the brain to stimulate a muscle to contract. when the simulation stop, the muscle relaxe.

motor nerves control the body's voluntary muscular contraction

muscle cant function properly if nerve impulse damage

neuromuscular - pertaining to the relationship btw a nerve & muscle

contraction - tightening the muscle. when muscle contract, it become shorter & thicker, cause the belly ( center) of muscle enlarge

relaxation - occur when muscle return to its original form, become longer & thinner. Belly no longer enlarge
