Generally, skeletal muscle tissue contracts in response to a signal from the nervous system. The skeletal muscles of one side of the body are controlled by the opposite side of the brain.

Thus, injury to the left side of the brain tends to result in paralysis of the right side of the body. The nerves of the body extend from the CNS to the individual muscles.

Going to the individual skeletal muscle is the neurovascular bundle. This contains the NAVL for that muscle within a common FCT sheath. The point where this bundle enters the muscle is called the motor point.

In a clinic or laboratory, this is the last point where a stimulus can be applied to make the whole muscle contract.
