z Names Associated with Muscle Movements § Adduction/Abduction § Flexion/Extension § Rotation § Pronation/Supination § Plantar Flexion/ Dorsiflexion

z Adduction § Adduction is the movement of a body part toward the body's midline. § If a person has their arms straight out at the shoulders and brings them down to their sides, it is adduction. § If it is a person’s fingers, movement towards the middle of the center of the hands. § Example: Lat Adduction Exercises.

z Flexion § Flexion is a joint movement that DECREASES the angle between the bones that converge at the joint.

z Extension § Extension is the opposite of flexion, describing a straightening movement that INCREASES the angle between the bones that converge at the joint.

z Rotation § Rotation is movement in which something, e. g. a bone or a whole limb, pivots or revolves around a single long axis.

z Pronation/Supination § Pronation and supination are a pair of unique movements possible only in the forearms and hands, allowing the human body to flip the palm either face up or face down. § Easy way to remember…SOUPination = holding a bowl of soup in your hand.
