cervical vertebrae
thoracic vertebrae
the sternum
fontanels
lumbar vertebrae
sacrum & coccyx
Fractures
Greenstick : incomplete and a break occurs on convex surface
fissured : incomplete long break
communited - copleted and fragments on the bone
transverse - complete and breaks occuree at a right angle
oblique - occurs at an angle than other than a right angle
spiral - aused by exercise twisting of bone
differences between male and female skelton
Female skeleton is smoother nd less knooby than a males skeleton
males skeletons are thicker and rougher and appear more bumby since males have stronger and larger muscles
movements allowed by synovial joints
flexion - bending parts angle decreases
extension - starightening - parts angle increases
lateral flexsion - bending neck , or trunk to side
hyperextension - staright
abduction - moving a baody part away from midline
dorsiflexion - ankle movement moes foot closer to shin
plantar flexsion - ankle moves farther from shin
rotaion - movemnt of part circular path
pronation - palm facing down
supination - palm facing down
inersion - turning sole
protraction - moving body part foward
retraction - moving body part backwards
elevation - raising body part
types of bones
long - long with expanded ends
short - alomost equal in length
flat - plate like shaped with board surface
irregular - varied shapes
anatomy of long bones
epiphyses - explanded ends of bones that fom joints with adjacent bones
artucular cartilage - covers epiphyses
diaphysis - shaft of the bone
periosteum - tough layer of dense connective tissue that covers bone and ligament and tendons
medullary - hallw chmaber within diaphysis
endosteum - medullary caviy lined with a thi layer of cells
bone marrow - medullar cavity filled with special type of connective tissue
bony processes - provides attachment sites for tendons and ligamnets
comapct bone s- a very tightly packed tissue . makes up wall of diahysis
spongy bones - consists of many braches bony plate
bone remodling
activition
resorption
reversal
formation
quiescence
bone fracture
fracture - break in bone s
compound (open ) fracture - whe broken bone is exposed to the outusde by and opening of the skin
when bone breaks blood vessels in the rupture , peritoneum is likely to tear
blood through broken vessles sreads through the damaged and forms blood clot
osteoblast divide , regions close to te new blood build spongy nearby
granulation tissue developed
fibrocartialge fill the gap between the ends of a broken bone
joints
fibrous joints
most moveable ( ex - sutures of skull )
cartilaginous
connected by hyaline or fibrocartilage - slightly moveable not as much
synovial
menisci - synovial joints contain shock absorbing pads of fibrocartilage
bursae - fluid scacs that have movement of tendons as they slide over
