A&P 1 CH 9-11
Dr. Cutler SU-Articulation+Motion-Muscle Tissue-Muscular System
| articulation/arthrosis | point of contact between bones, cartilage, or teeth |
| arthology | study of joints |
| joint stability | ligaments + interosseous membranes |
| connective tissues | restrictive + elastic |
| classes of STRUCTURAL joints (connective tissue) | fibrous, cartilaginous, synovial |
| classes of FUNCTIONAL joints (movement) | synarthrosis, amphiarthrosis, diarthrosis |
| synarthrosis | immoveable-epiphyseal growth plate |
| amphiarthrosis | slightly movable-pubic symphysis |
| diarthrosis | freely movable |
| fibrous joints | these area all synarthrotic (immovable) |
| suture | fused skull bones, immovable |
| syndesmosis | wrist and ankle with slight movement |
| gomphosis | tooth and socket connection |
| fibrocartilage pad | grows inside joint cavity-knees + tmj |
| synovial joints | diarthrotic-joint cavity, fibrous capsule, ligaments |
| gliding plane joint | between the nasal bones of the foot and the carpal bones of the wrist |
| hinge joint | between the trochlea of humerus and the trochlear notch of ulna at the elbow, knees, and fingers |
| pivot joint | head of radius and radial notch of ulna or odontoid prowess of axis and atlas |
| condyloid joint | between the distal arm and wrist bones and between the distal leg and ankle bones |
| saddle joint | between the trapezium of carpus and metacarpal of thumb |
| ball and socket joint | between head of femur and acetabulum of hip bone |
| osteoarthritis | wear and tear on cartilage |
| rheumatoid arthritis | pannus |
| gouty arthritis | uric acid build up |
| lyme disease | dear tick; bullseye rash |
| ankylosing spondylitis | fusion if vertebrae |
| flexion | decrease angle of 2 bones |
| extension | increase angle of 2 bones |
| lateral flexion | side bending |
| aBduction | away from midline |
| aDduction | to the midline |
| rotation | turn on a axis |
| pronation | palm down |
| supination | palm up |
| eversion | sole of foot outward |
| inversion | sole of foot inward |
| circumduction | form a cone (make circle in the air) |
| dorsiflexion | foot and toes up |
| plantarflextion | foot and toes down |
| skeletal muscle tissue | voluntary, striated (striped) moves bones and joints |
| cardiac muscle tissue | involuntary, pacemaker cells, intercalated discs |
| smooth muscle tissues | involuntary, hollow organs (GI tract), blood vessels |
| properties of muscle tissue - excite | responsive to stimulus from nervous system (stretching) |
| properties of muscle tissue - contract | tension created when muscle is stimulated; shortening causes pull on bones or movement |
| properties of muscle tissue - elastic | recoils to resting length after tension is removed |
| properties of muscle tissue - extends | extends when opposing muscle is contracted (flexed) |
| functions of muscle tissue | body movement, posture, temp regulation, storage and movement of materials, support |
| fascicle | bundle of muscle fibers ("belly of a muscle") |
| muscle fibers | another name for a muscle cell |
| sarcomere | contractile unit of a muscle fiber |
| sarcoplasmic reticulum | hollow tubes that stores calcium |
| ct in muscles | encircles each individual muscle fiber, group of muscle fiber and the entire muscle itself |
| endomysium | intermost layer surrounds each muscle fiber |
| perimysium | surrounds fascicles |
| epimysium | outermost layer surrounds entire skeletal muscle |
| deep fascia | separates individual muscles, binds together muscles with similar functions, fills space between muscles |
| superficial fascia | separates muscle from skin |
| tendon | where connective tissue layers MERGE at the end of a muscle, attach muscle to bone |
| aponeurosis | a thin, flat sheet of tendon |
| origin | the less moveable attachment of a muscle, usually promimal |
| insertion | the more moveable attachment of a muscle, usually distal |
| motor neurons | nerve cells that stimulate muscles contraction |
| axon | nerve fiber |
| neuromuscular junction | junction between axon and muscle fiber itself |
| sarcolemma | plasma membrane of muscle fiber, TRANSVERSE TUBULES (T-TUBULES), transmits nerve signal |
| sarcoplasm | cytoplasm of a muscle fiber |
| sarcoplasmic reticulum (SR) | reservoir for calcium ions, TERMINAL CISTERNAE |
| myofibril | long cylinder shaped structures in a skeletal muscle fiber, shorten during muscle contraction |
| myofilaments | make up myofibrils: ACTIN & MYOSIN PROTEINS |
| actin | thin filament, have binding cites for myosin(girl) |
| myosin | thick filament, heads of myosin stick out toward actin, binding site for actin (boy) |
| troponin | bound to actin holds tropomyosin in place so it can cover the myosin binding site |
| tropomyosin | bound to actin, covers the myosin binding site, moves away from actin when she gets a "kiss" |
| contractile proteins | myosin + actin |
| regulatory proteins | troponin + tropomyosin |
| fascicle organization (muscle pattern) | parallel, convergent, pennate, circular |
| third class lever | most common lever |
| most running injuries involve | the knee |
