| Question | Answer |
|---|---|
| adult skeleton consist of how many bones? | 206 |
| the five primary functions of the bones | support; protect internal organs; anchor for muscles to enable movement; storage for minerals; site for blood cell formation |
| skeleton has two major divisions | appendicular and axial |
| appendicular skeleton is consisted of | 126 bones: shoulder; arms; wrists; hands; hip; legs; ankles; and feet |
| axial skeleton is consisted of | 80 bones; skull; spine; ribs; sternum; hyoid bones |
| vertebrae is made up of | 5 cerivcal; 12 thoracic; 5 lumbar; sacrum(5 bones fused together); coccyx (4 bones fused together) |
| purpose of muscles | attach to skeleton; enable movement; give body shape; maintain posture |
| types of muscle | skeletal; smooth and caridac |
| supporting structures | tendons; ligaments; joints |
| injury to a muscle or tendon caused by excessive use or overexcertion | strain |
| trauma to ligament, muscle or tendon usually caused by a twisting motion | sprain |
| temporary displacement of a bone from its usual position in a joint | dislocation |
| break in the bone | fracture |
| realign bones to their original position | reduction |
| bone is completely broken into two or more pieces | complete fracture |
| bone is partially broken | incomplete fracture |
| bone is partially bent and partially broken | greenstick |
| fracture that occurs as a result of twisting the bone | spiral fracture |
| fine hairline fracture as a result of repeated trauma | stress fracture |
| bone is broken and goes through the skin | open(compound) fracture |
| fracture due to a disease condition that weakens the bone | pathological fracture |
| disease resulting in weak and brittle bones | osteoporosis |
| inflammatory process that affects the joints | arthritis |
| a severe twist of the knee can result in this injury | ACL injury |
| caused by compression of the median nerve located at the base of the palm | carpal tunnel syndrome |
| inflammation caused by too much tension on the fascia of the foot | plantar fascitis |
| inflammation of the bursa of a joint | bursitis |
| stiff device that is used to support and immobilize an injured body part | splint |
| used for more long term immobilization of a broken bone | cast |
| this device is used when someone needs slight support on one side of the body | cane |
| this is used when weight bearing on a foot or leg is prohibited | crutches |
| when using axillary crutches how much space should there be between the axillary and crutch pads | 3 finger widths |
| most common crutch gait used when one leg is non weight bearing | three point gait |
| provides the most support and stability for pt with balance and coordination issues | walker |
| xrays that produce cross sectional views of a body part | CT scan |
| uses magnetic waves to produce images of the body part | MRI |
| permanent film record of a body part | xray |
| four most common orthopedic surgeries | total joint replacement; total shoulder replacement; spine surgery; ACL repair |
| therapy to develop maintain and restore movement to the musculoskeletal tissues | PT (physical therapy) |
| therapy that may be used during PT | ultrasound; electrical stimulation; hydrotherapy; thermotherapy; cryotherapy |
| gentle movement of a joint through its normal range of motion | ROM |
| movement away from the midline of the body | abduction |
| movement toward the midline of the body | adduction |
| move body part in a circular motion | circumduction |
| turning outward | eversion |
| to turn inward | inversion |
| turning the palm downward | pronation |
| turning the palm upward | supanation |
| to straighten | extension |
| to ben | flexion |
| drugs used to decrease inflammation | steroids and NSAIDS |
| drugs that prevent loss of bone mass | bisphosphates |
| drugs that decrease or relax smooth muscle | muscle relaxors |
| examples of NSAIDS | ibuprofen; naprosyn |
| examples of bisphosphonates | boniva; fosamax |
| examples of muscle relaxors | flexaril; robaxin; valium |
