Skeletal Anatomy Flashcards
Axial Skeleton
The portion of the skeleton consisting of the skull, spine, ribs, and sternum.
Anatomical position
Person stands with arms at the sides and palms facing forward.
appendicular skeleton
The portion of the skeleton consisting of the upper and lower limbs, the pelvic girdle, and the shoulder girdles.
synovial joints
A common joint in the human body that connects two bones and allows the movement of the bones associated with it.
flexibility
absolute range of motion, or relative range of motion, of a joint as a result of muscles that cross the joint.
medial
closer to midline
lateral
further from midline
inferior
below
superior
above
dorsal
top
plantar
bottom
distal
farther end
proximal
closer end
supine
lies up
prone
face down
supination
external movement from midline
pronation
movement toward the midline
flexion
bending a joint
extension
straightening
hyperextension
beyond range of motion
abduction
moves away
adduction
bones move toward midline
circumduction
circular movement that combines flexion, abduction, extension, adduction. (ball & socket)
elevation
upward shoulder shrugging
protraction
(abduction)
retraction
(adduction)
lateral rotation
rotation away from midline
inversion
turning the medial, inner side of the foot off the ground toward midline.
eversion
The outer side off the ground away from midline.
dorsiflexion
flexing foot upwards
plantar flexion
flexing foot downwards
spinal stabilization system
A system containing the nerves, joints, and muscles of the spine, which allows proper spinal function and lower back health.
