For the thumb, extension moves the thumb away from the palm of the hand, within the same plane as the palm, while flexion brings the thumb back against the index finger or into the palm. Abduction and adduction movements are seen at condyloid, saddle, and ball-and-socket joints (see Figure9.5.1.e). Uniaxial joint; allows rotational movement, Atlantoaxial joint (C1C2 vertebrae articulation); proximal radioulnar joint, Uniaxial joint; allows flexion/extension movements, Knee; elbow; ankle; interphalangeal joints of fingers and toes, Biaxial joint; allows flexion/extension, abduction/adduction, and circumduction movements, Metacarpophalangeal (knuckle) joints of fingers; radiocarpal joint of wrist; metatarsophalangeal joints for toes, First carpometacarpal joint of the thumb; sternoclavicular joint, Multiaxial joint; allows inversion and eversion of foot, or flexion, extension, and lateral flexion of the vertebral column, Intertarsal joints of foot; superior-inferior articular process articulations between vertebrae, Multiaxial joint; allows flexion/extension, abduction/adduction, circumduction, and medial/lateral rotation movements, Define the different types of body movements, Identify the joints that allow for these motions. a fishing excursion. Angles are used to define the orientation of these lines or planes relative to each other. This crossing over brings the radius and ulna into an X-shape position. These movements are used to shrug your shoulders. You can feel this rotation when you pick up a load, such as a heavy book bag and carry it on only one shoulder. Extension is otherwise known as straightening. (h) Dorsiflexion of the foot at the ankle joint moves the top of the foot toward the leg, while plantar flexion lifts the heel and points the toes. Lateral excursion moves the mandible away from the midline, toward either the right or left side. Because of the slight curvature of the shaft of the radius, this rotation causes the distal end of the radius to cross over the distal ulna at the distal radioulnar joint. In the anatomical position, the upper limb is held next to the body with the palm facing forward. Similarly,hyperflexionis excessive flexion at a joint. When the palm of the hand faces backward, the forearm is in the pronated position, and the radius and ulna form an X-shape. Discount fares are typically offered for a limited time. When the mandible moves to either the left or right, it's moving away from the body's midline, so it's called lateral excursion. - bone turns about its longitudinal axis. Pronation is the motion that moves the forearm from the supinated (anatomical) position to the pronated (palm backward) position. Mean joint excursion and the variance in joint excursion are lower for the jaw compared with all limb joints. These motions take place at the first carpometacarpal joint. I did not find a clear-cut definition either, but after reviewing several sites I will describe the term as: a deviation from parameters. Excursion is the side to side movement of the mandible. Normal end feel is when the joint has full ROM and the range is stopped by the anatomy of the joint. Watch this video to learn about anatomical motions.

These movements take place at the shoulder, hip, elbow, knee, wrist, metacarpophalangeal, metatarsophalangeal, and interphalangeal joints. Protraction and retraction are anterior-posterior movements of the scapula or mandible. Movement that brings the anterior surface of the limb toward the midline of the body is called medial (internal) rotation. Rotation can also occur at the ball-and-socket joints of the shoulder and hip. Supination and pronation are movements of the forearm. During superior rotation, the glenoid cavity moves upward as the medial end of the scapular spine moves downward.
