Joint Movements Overview

Study Notes

Joint Movements

Flexion: Movement that decreases the angle between body parts, moving anteriorly to the coronal plane.
Extension: Movement that increases the angle between body parts, moving posteriorly to the coronal plane.
Plantar Flexion: Action of standing on the toes, engaging the calf muscles.
Dorsiflexion: Movement where the foot is lifted toward the shin, decreasing the angle at the ankle joint.
Abduction: Movement that occurs away from the median plane, crucial for limb movements.
Adduction: Movement toward the median plane, typically in returning limbs towards the center of the body.
Rotation: Turning of a body part around its long axis, essential for actions at joints like the shoulder and hip.
Pronation: Twisting motion of the hand that turns the palm downward, involves certain forearm muscles.
Supination: Opposite of pronation; twisting the hand so that the palm faces upward.
Circumduction: A circular movement that combines flexion, extension, abduction, and adduction, often seen in shoulder and hip joints.
Elevation: Movement that raises a body part superiorly, such as shrugging shoulders.
Depression: Movement that lowers a body part inferiorly, such as returning shoulders to resting position.
Protraction: Anterior gliding motion of a structure, visible in movements like pushing the jaw forward.
Retraction: Movement that moves a structure back to anatomical position or further posterior; important for movements of the jaw and shoulders.
Lateral Excursion: Side-to-side movement of the mandible, allowing for grinding motion during chewing.
Medial Excursion: Movement that returns the mandible to the midline after lateral excursion.
Inversion: Ankle movement where the sole of the foot turns medially, often stabilizing the ankle.
Eversion: Ankle movement where the sole of the foot turns laterally, helping with balance and posture.
