It helps to remember that supination is the motion you use when scooping up soup with a spoon (see Figure 4). These are the only movements available at the ankle joint (see Figure 4). These movements of the vertebral column involve both the symphysis joint formed by each intervertebral disc, as well as the plane type of synovial joint formed between the inferior articular processes of one vertebra and the superior articular processes of the next lower vertebra.

This allows the head to rotate from side to side as when shaking the head “no.” The proximal radioulnar joint is a pivot joint formed by the head of the radius and its articulation with the ulna. For the vertebral column, flexion (anterior flexion) is an anterior (forward) bending of the neck or body, while extension involves a posterior-directed motion, such as straightening from a flexed position or bending backward. This motion is produced by rotation of the radius at the proximal radioulnar joint, accompanied by movement of the radius at the distal radioulnar joint. Circumduction is the movement of a body region in a circular manner, in which one end of the body region being moved stays relatively stationary while the other end describes a circle. (a)–(b) Flexion and extension motions are in the sagittal (anterior–posterior) plane of motion. Abduction and adduction motions occur within the coronal plane and involve medial-lateral motions of the limbs, fingers, toes, or thumb. Lateral flexion is the bending of the neck or body toward the right or left side. Flexion and extension.
At a pivot joint, one bone rotates in relation to another bone. Superior rotation is also used without arm abduction when carrying a heavy load with your hand or on your shoulder. This crossing over brings the radius and ulna into an X-shape position. Plant & Animal Cells Staining Lab Answers, Effects of Information Technology on Society. Hinge joints allow flexion and extension only. Inversion, eversion, protraction, and retraction. Abduction and adduction movements are seen at condyloid, saddle, and ball-and-socket joints (see Figure 2). Superior and inferior rotation are movements of the scapula and are defined by the direction of movement of the glenoid cavity. Medial and lateral rotation of the upper limb at the shoulder or lower limb at the hip involves turning the anterior surface of the limb toward the midline of the body (medial or internal rotation) or away from the midline (lateral or external rotation). Inversion is the turning of the foot to angle the bottom of the foot toward the midline, while eversion turns the bottom of the foot away from the midline. Hyperextension is the abnormal or excessive extension of a joint beyond its normal range of motion, thus resulting in injury. In the limbs, flexion decreases the angle between the bones (bending of the joint), while extension increases the angle and straightens the joint. Abduction and adduction are motions of the limbs, hand, fingers, or toes in the coronal (medial–lateral) plane of movement.

(a) Depression of the mandible opens the mouth, while elevation closes it. Turning of the head side to side or twisting of the body is rotation. Figure 4. The wheel rotates around a centre point.
