Anatomy Terms Describing Movement Flashcards
flexion
bones come closer together, joint angles become smaller
extension
joint angles become larger, bones move farther away
hyperextension
a joint extending beyond the normal range of motion; most often in knees and elbows
abduction
moving an arm or leg laterally (out to the sides) and away from the midline
adduction
moving an arm or leg away from the sides and in toward the midline
medial (internal) rotation
bone is turning inward at the joint
lateral (external) rotation
bone is turning outward at the joint
rotation
“pure” rotation occurs only in the spine
unilateral movement
occurring on one side of the body
bilateral movement
muscles on both sides of the body work together
lateral flexion
movement only performed by the spine, side bending
circumduction
making big circles at the ball-and-socket joints in pelvis and shoulders, combines movement of flexion, extension, abduction, and adduction
supination
movement that occurs in the forearm and foot; turning the palm to face forward; turning foot inwards
pronation
opposite of supination, movement in forearm and foot; turning the palm toward the back; turning the foot out to the side
plantar flexion
pointing your toes
