Question | Answer |
---|---|
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 |
