| Flap 1 | Flap 2 |
| Osteology | Study of the skeletal system |
| Arthrology | study of joints (articulations) |
| Myology | Study of muscles |
| Neurology | Study of nerves |
| Abduction | Away from the midline |
| Adduction | Toward the midline |
| Flexion | Decreases the angle of joint |
| Extension | Increases the angle of join |
| Lateral Rotation | Rotation away from the midline |
| Medial Rotation | Rotation toward the midline |
| Synarthrodial | Immovable joint |
| Amphiarthrodial | Slightly movable joint |
| Diarthrodial | Freely movable joint |
| Syndesmosis | Joint held together by ligaments |
| Symphysis | Joint separated by a fibrocartilage pad |
| Synchondrosis | Joint separated by a hyaline cartilage pad |
| Arthrodial | Only movment allowed is gliding |
| Condyloidal | Flexion, extension, abduction, adduction |
| Ginglymus | Flexion, extension |
| Enarthrodial | Flexion, extension, abduction, adduction, lateral rotation, medial rotation |
| Trochoidal | Medial rotation, lateral rotation |
| Saddle | Flexion, extension, abduction, adduction, opposition |
| Superficial fascia | Composed of areolar and adipose tissue immediately under the skin |
| Deep fascia | Made of fibrous connective tissue filled with collagen |
| Epimycium | surrounds the belly of a muscle |
| Perimycium | Surrounds a fascicle (bundle of muscle fibers) |
| Endomycium | Surrounds a single muscle fiber |
| Excitability | The ability of a muscle to respond to a threshold stimulus or more |
| Contractility | Ability of muscles to shorten or thicken |
| Extensibility | The ability of muscle to stretch beyond its original length |
| Elasticity | Ability of muscle to recoil back to its original length after stretching |
| Parallel | Less fibers, greater ROM, less power |
| Pennate | More fibers, less ROM, greater power |
| Isometric | A muscle contraction htat produces tension in a muscle without movement |
| Isotonic | A contraction in which tension remains constant as muscle shortens or lengthens |
| Concentric | Muscle shortens, anti-gravity or resistance |
| Eccentric | Muscle lengthens, yields to gravity or resistance |
| Skeletal Muscle | Voluntary, Striated |
| Cardiac Muscle | Involuntary, Striated |
| Smooth Muscle | Involuntary, Non-Striated |
| Sarcomere | The functional contractile unit of skeletal muscle |
| Actin | Thin myofilament |
| Myosin | Thick myofilament |
| Motor neuron | The nerve fiber that gives the muscle the order to contract |
| Motor unit | A motor neuron plus all the muscle fibers it innervates |
| Threshold stimulus | The minimal level of stimulus required to cause a muscle fiber contraction |
