Final answer:
Angular movements at joints include flexion, extension, hyperextension, abduction, adduction, and circumduction. Flexion is the bending movement that decreases the angle between bones, while extension is the opposite. Abduction moves the limb away from the midline, while adduction brings the limb toward the midline.
Step-by-step explanation:
Angular movements at joints include flexion, extension, hyperextension, abduction, adduction, and circumduction. Flexion is the bending movement that decreases the angle between bones, such as moving the forearm upward at the elbow. Extension is the opposite of flexion, increasing the angle between bones, like straightening a limb after flexion. Abduction moves the limb away from the midline of the body, while adduction brings the limb toward the midline. Circumduction is the circular movement of a body region where one end stays relatively stationary while the other end describes a circle.
