Chap. 3 Muscle Parts; Directional Mvmts; D & C; Tests, Procedures, Procedures & Therapeutics; TX Flashcards
origin
the attachment site that does not move when the muscle contracts; the end of the muscle that is anchored or where no motion takes place
insertion
the attachment site that moves during muscular contraction; the opposite end of the origin where motion takes place at a joint
tendon
a band of fibrous tissue that connects muscle to bone; ex: the achilles _______ attaches to the gastrocnemius muscle on the calf of the leg to the calcaneus or heel bone
ligaments
a fibrous cord of tissue that attaches bone to bone; usually impacts stability by holding structures together; contributes greatly to joint stability
agonist
the muscle that produce the primary movement
antagonist
the muscle that works against the movement; opposite movement
abduction
movement of a body part away from the midline
adduction
movement of a body part toward the midline
inversion
turning the sole of the foot inward
eversion
turning the sole of the foot outward
elevation
raising a body part (shoulders)
depression
lowering a body part
flexion
bending a joint or decreasing the angle
extension
straightening a joint; increasing the angle
hyperextension
straightening a joint beyond it’s normal range of motion
dorsiflexion
bending your ankle so your toes are up
plantar flexion
bending your ankle so your toes are towards the plants
rotation
movement of a body part around its longitudinal axis
pronation
turning the palm of your hand dorsally
supination
turning the palm of the hand ventrally
circumduction
rotation of the limb in a circle
opposition
approximating of the thumb to each finger
