| Lactic | | The main component of thin filaments |
| Troponin | | Action potentials travel along the sarcolemma and through these (two words) |
| Contractility | | These cells are able to fuse and make new muscle fibre |
| Transversetubules | | The function of this muscle types is to "pump" blood through the circulatory system |
| CreatinePhosphate | | Excess ATP produced in muscle is stored in the form of this |
| Skeletal | | The basic functional unit of a myofibril |
| Cardiac | | The ability to contract forcibly |
| NeuromuscularJunction | | A special characteristic of cardiac muscle |
| Elasticity | | This type of contraction occurs when tension in the muscle remains constant despite a change in muscle length |
| Myoglobin | | This kind of contraction is a contraction of all the muscle fibers in a motor unit in response to a single action potential in a motor neuron |
| Isotonic | | In this type of contraction, the force generated is sufficient to overcome the resistance, and the muscle shortens as it contracts |
| Endomysium | | The cell (plasma) membrane of a muscle fibre or muscle cell |
| Tetanus | | In a relaxed muscle fibre, this |
| Isometric | | The contractile unit of muscles |
| Sarcolemma | | Recovery oxygen consumption used to be called this |
| Myofibril | | The type of muscle we use for voluntary movement |
| Extensibility | | The most abundant protein in muscle |
| Glycosomes | | Is a protein (only found in muscle) that receives oxygen from hemoglobin and stores it in the tissues until needed |
| Satellite | | This protein anchors a thick filament to the Z disc and M line thus it helps to stabilize the position of the thick filament |
| SuperficialFascia | | When this ion is released from the terminal cisterns of the SR, muscle contraction occurs |
| Actin | | A layer of connective tissue which ensheaths the entire muscle |
| Eccentric | | This protein helps anchor the thin filaments to the Z discs |
| Calcium | | A layer of connective tissue that ensheaths a muscle fibre |
| Fermentation | | This type of contraction occurs when the muscle remains the same length despite building tension |
| Concentric | | The adipose tissue of this (two words) stores most of the body’s triglycerides |
| SynapticVesicles | | The inability of a muscle to maintain its strength (force) of contraction or tension after prolonged activity is called this |
| Myomesin | | The ability to return to its original shape after being stretched |
| Hyperplasia | | These proteins form the M line at the very center of the sarcomere |
| Hypertrophy | | This is attached to the protein tropomyosin and lies within the groove between actin filaments in muscle tissue |
| Titan | | An increase in the number of muscle fibers |
| Epimysium | | Unconscious nerve impulses maintain the muscles in a partially contracted state - this is called |
| Autorythmicity | | Anaerobic respiration results in the production of this kind of acid |
| Nebulin | | Synaptic end bulbs contains many of these |
| SarcoplasmicReticulum | | Anaerobic respiration is commonly known as this |
| Myosin | | The ability to stretch without being damaged |
| OxygenDebt | | In this type of contraction, the force generated is insufficient to overcome the resistance placed on the muscle and the muscle fibers lengthen as they contract |
| Twitch | | This is the chemical used at the NMJ |
| MuscleFatigue | | An enlargement of existing muscle fibers |
| Neurotransmitter | | Granules of stored glycogen |
| MuscleTone | | This is a medical condition characterized by a prolonged contraction of skeletal muscle fibers |
| Sarcomere | | In a relaxed muscle, this blocks the attachment site for myosin on the actin protein |
| Tropomyosin | | The site of interaction between the nervous and muscular systems |
