| Question | Answer |
| Agonist | The muscle Primarily responsible for producing movement |
| Antagonist | The muscle that relaxes as the agonist contracts to allow ease of movement and minimise the risk of injury |
| Stabilisers | Muscles that act to stabilise the bone where the prime mover is acting to allow efficiency of movement and maximum contractile force to be developed if required |
| Reciprocal inhibition | When muscles on one side of a bone of a bone or joint relax to accomodate contraction on the other side of the bone or joint |
| All or Nothing Principle | Either the whole muscle contracts or none of the muscle contracts |
| Capillary Density | |
| Phosphocreatine Stores | |
| Triglyceride Stores | The optimum state of fatty acids in order to enable storage |
| Isotonic Contractions | Most Common type of Muscle Contraction, If a muscle shortens during a contraction then a concentric isotonic contraction has occured. For example: A bicep curl as you curl the angle decreases |
| Isometric Contractions | Involves little if any, change in muscle length while tension is developed |
| Smooth Muscle | These are found internally in blood vessels and walls of the intestine. They are made up of Spindle Cells |
| Cardiac Muscle | These muscles make up the walls of the heart. They are involuntary and have striped appearance |
| Skeletal Muscle | These external muscles are attatched to the bones that make up the skeletonn. They are under your direct control which is known as Voluntary muscles. |
