skeletal system
Question | Answer |
---|---|
skeletal system composed of: | bones: 206 (most in feet and hands) |
6 functions: | *stability support *protection (brain, heart lungs) *RBC/WBC production in bone marrow *mineral storage: calcium, phosphorus, magnesium, sodium *movement: lever systems *fat storage |
divisions 1 of 2: | axial skeleton:80 bones *skull:29 *vertebrae:26 *sternum:1 *ribs:24 total, 7 true, 3 false, 2 floating |
long: | arms/legs (longer than wide) |
steoblates: | builds bone |
ossification: | process of bone development/building |
epiphysis: | ends of bones |
epiphyseal plate: | growth plate between bones |
periosteum: | connective tissue |
between bones: | tib/fib, radius/ulna |
spine disorders | *kyphosis:humpback *lordosis:swayback *scoliosis:"scure of spine" |
joints: | where bones meet |
cartilage: | between our bones |
connective tissue: | holds joints together |
ligaments: | connects (bone/bone) |
tendons: | connects (muscle/bone) |
short: | cube shaped: carpal/torsels |
flat: | sternum/scapula |
sesmoid: | bone embedded in tendon: patella/skull |
irregular: | everything else (vertebrae,pelvis,ribs) |
divisions 2 of 2: | apendigens/appendicular skeleton:126 bones *shoulder gridle: 4 *upper limb: 60 total/30per side *pelvic gridle: 2lower *limb: 60 |
osteocytes: | matures bone |
osteoclats: | breaks down bone |
