|
| 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 |
