APPLIED RADIOLOGICAL ANATOMY

Detailed explanation-1: -Ball and socket joint – the rounded head of one bone sits within the cup of another, such as the hip joint or shoulder joint. Movement in all directions is allowed.

Detailed explanation-2: -Ball and socket joint: It is a joint in which the rounded end of one bone fits into the cavity (hollow space) of the other bone. Such a joint allows movements in all directions.

Detailed explanation-3: -A ball and socket joint allows greater movement as compared to a hinge joint. A typical hinge joint allows movement in a single plane such as backward, forward, down and up movements. A ball and socket joint, on the other hand, allows movement in all directions such as rotational movements.

Detailed explanation-4: -Movements. The ball and socket configuration allows for movement with 3 degrees of freedom, which is more than any other type of synovial joint. The depth of the cup and any additional fibrocartilaginous labrum is the major limitation to the extent of motion allowed in any direction.

Detailed explanation-5: -Hinge joints are a type of joint that functions much like the hinge on a door, allowing bones to move in one direction back and forth with limited motion along other planes.
