Skeleton System
Chapter 7 and 8
| bone classifications | long, irregular, short, flat, sesamoid |
| long bone parts | articular cartilage, diaphysis, distal epiphysis |
| # of bones in body | 206 |
| Compact bone | central canal, lacunae, lamella |
| Cranium bones | partieal, squamous suture, temporal, external acoustic, frontal, corral suture, and sphenoid |
| facial bones | ethmoid, lacarimal, nasal, zygomatic, maxilla, mental foarem, mandible, coronoid process, styloid |
| full body bones | cranium (brain), hyoid, clavicle, vertebrate column, carpals, metacarpals, sternum, humerus, ribs, hipbones, radius, ulna, femur, patella, fibula, tarsals, metatarsals, phalanges, coccyx, sacrum, tibula, calcaneus, patella |
| Syndesmoid | bones are bound by long fibers of connective tissue forming the interosseous ligament |
| suture | the sutural ligament is a thin layer of dense connective tissue found in between the flat bones of the skull after growing together |
| Gomphosis | the peg-like root of a tooth fastened to the jawbone by periodical legament |
| Synchondrosis | many of these structures are temporary and will disappear during growth |
| symphysis | joint is the articular surface that is separated by a thin layer of hyaline cartilage attach to a band of fibrocartilage |
| Synovial | joints that are diarthrotic (free movement) |
| names of fibrous joints | syndemosis, suture, gomphosis |
| cartilage joints | synchondrosis, symphysis |
| synovial joints | articular cartilage, joint cavity, joint capsule, synovial membrane, synovial fluid, meniscus |
| flexion | bending the bone (action) |
| extension | moving the bone outward |
| hyperextension | exercise that works the lower back and (extend bone greater than normal) |
| Dorsiflextion | backwards flexion (bending) |
| Plantar flexion | the act of bending or the condition of being bent |
| abduction | the movement of a limb or other part away |
| adduction | is the movement of a body part toward the body's midline. |
| Rotation | moving a part around the axis |
| circumduction | moving apart so that it sends follow a circular path |
| supuration/pronation | rotation of forearm so the palm is upward or facing anteriorly |
| eversion/inversion | refer to movements that tilt the sole of the foot away from |
| protraction/retraction | rotation of forarms that the palm is downward or facing posteriorly |
| elevation/depression | raising a part (shrugging the shoulders) moving the head up and down |
| sprains | over stretching or tearing of connective tissue |
| brsitis | inflammation of the bursa can be caused by over use |
| arthritis | painful inflammation and stiffness of the joint |
| RA | autoimmune disorder chronic with flairs |
| OA | most common type of arthritis the articular cartilage softens and distingerates as age |
| Lyme | infection by a tick carried germs leads to inflammation of the synovial membrane |
| gout | acute inflammation of a joint |
