Skeletal System Flashcards
(50 cards)
sutures
immovable joints in bones
fontanels
soft spots that allow compression of the skull during birth
epiphyseal fracture
the epiphyseal plate separates from the diaphysis or epiphysis due to stress
avulsion fracture
muscle contraction pulls away a piece of the underlying bone
lordosis
when your lumbar spine curves in towards yours your body (
kyphosis
outward curve of the thoracic spine (hunch back) )
scoliosis
spine makes an s curve- abnormal side to side spine curve
sinuses
spaces or cavities inside some cranial bones
mastoiditis
inflammation of the air spaces within the mastoid portion of the temporal bone
ligament
connects bone to bone
ball and socket joint
bone with a ball shaped head fits into a concave socket of a 2nd bone.
- most movement of any of any joint.
- hips and shoulder
hinge joint
moves in one direction
- knees, elbow, joints of phalanges
pivot joint
one bone rotates another
- radius and ulna
saddle joint
allows movement in two or more directions
- sternoclavicular joint, thumb
gliding joint
flat surfaces glide against each other back and forth and turning
- wrist and vertebrae
compound (open)
fracture where bone comes through skin. increased possibility of infection.
subluxation
dislocation occurs but goes back in on its own
sprain
ligament injury
strain
tendon injury
dislocation
joint becomes “out of place’. forced out of correct location
osteoarthritis
degenerative joint disease
-most common non-inflammatory disease of moveable joints
- localized tenderness, morning stiffness, pain from movement
synarthroses joint
Does not allow movement between bones
- sutures of the skill
amphiarthroses joint
allows slight movement between bones
-pubic bones, vertebrae
diarthroses joint
allows lots of movement between bones
-hip, knees, fingers
