Increase angle of joint
WebTo achieve movement, the joint may: Slide one broad and flat surface across another – examples include the bones in the wrist or ankle. Increase or decrease the angle between the two bones – this only occurs in the long bones of the body (arms and legs): for example, when the arm is bent or extended. WebAngular movements are produced when the angle between the bones of a joint changes. There are several different types of angular movements, including flexion, extension, hyperextension, abduction, adduction, and circumduction. Flexion, or bending, occurs when the angle between the bones decreases.
