Skeletal System & Terms Reveiw
| Term | Description |
|---|---|
| diaphysis | tubular shaft of long bones |
| epiphysis | end portion of long bones |
| process | any projection or bump (coracoid process) |
| ramus | exension of bone making angle w/structure (vertical portion of mandible deep to masseter) |
| trochanter | large, rough projection - tendon or ligament attach (greater trochanter- gluteus medius, minimus and deep rotator muscles of femer attach) |
| tuberosity | small, rough projection - tendon or ligament attach (ischial tuberosity - sit bone, hamsrings, adductor magnus & sacrotuberous ligament attachment site) |
| tubercle | small round projection - tendon or ligament attach ( Lister's tubercle - dorsal surface of radial styloid process - extensor pollicis longus tendon attach) |
| epicondyle | projection (usually to side) on condyle - tendon or ligament attach -(epicondyles of humerus - medial site tendons of wrist & hand flexors. Lateral site for tendons of wrist & hand extensors. |
| crest | small round projection - tendon or ligament attach (pubic crest - rectus abdominis and abdominal aponeurosis) |
| line | low ridge - tendon or ligament attach (lina aspera on femur - Vastus Lateralis & Medialis attach) |
| spine | ridge - tendon or ligament attach (spine of scapula - posterior deltoid, middle and lower fibers of trapezius attach) |
| head - | articular end of epiphysis - articulation site bone to bone (head of radius - stablized by annular ligament - pivoting point for supination & pronation) |
| neck | between epiphysis and diaphysis |
| condyle | smooth rounded articular process articulation site bone to bone (femur) |
| trochlea | grooved articular process shaped like pulley - distal end of the humerus that articulates with the ulna. |
| facet | small, flat articular surface |
| fossa | shallow depression (infraspinous fossa) |
| sulus | narrow groove (depression) |
| foramen | passageway for vessles and nerves - opening (vertebral foramen) |
| canal | passage way through the substance of a bone - opening (vertebra canal for spinal nerve) |
