What does the term innervation refer to?

• A muscle’s anatomical location on the body

• The point where a muscle connects to bone

• A muscle’s point of connection to the nervous system

• The joint motion created by an eccentric contraction

Muscle origin

• The joint motion created when a muscle contracts concentrically

• The beginning attachment point of a muscle

• The joint motion(s) created when a muscle contracts eccentrically or isometrically

• Where the end point of a muscle connects back to the skeleton

Overactive/shortened muscles

• When inhibited neural drive allows a muscle’s functional antagonist to pull it into a chronically elongated state.

• An alteration of muscle lengths around a joint that allows it to be held in a suboptimal position.

• The synergistic function of muscles to produce movement around a joint.

• When elevated neural drive causes a muscle to be held in a chronic state of contraction.

• The rate and volume of activation signals a muscle receives from the CNS.

Underactive/lengthened muscles

• When inhibited neural drive allows a muscle’s functional antagonist to pull it into a chronically elongated state.
