Musculoskeletal System :) Flashcards
articulating bones
bones that meet and move at the joint
joint actions in sagittal plane + transverse axis
flexion extension hyper-extension plantarflexion dorsiflexion
joint action in frontal plane + sagittal axis
adduction
abduction
joint actions in transverse plane and longitudinal axis
horizontal adduction
horizontal abduction
agonist
muscle responsible for the movement that is occuring
antagonist
muscle that works in opposition to the agonist - produce coordinated movement

isotonic contraction
muscle contracts to create movemtn
concentric contraction
when muscle shortens under tension
eccentric contraction
when the muscle lengthens under tension (downward phase of movements)
isometric contraction
when the muscle contracts without lengthening or shortening
-no movement occurs-
