The ball-and-socket joint (or spheroid joint) is a type of synovial joint in which the ball-shaped surface of one rounded bone fits into the cup-like depression of another bone. The distal bone is capable of motion around an indefinite number of axes, which have one common center. This enables the joint to move in many directions.
A spherical S joint or ball and socket joint requires that a point in the moving body remain stationary in the fixed body. This joint has three degrees of freedom, corresponding to rotations around orthogonal axes. A planar joint requires that a plane in the moving body maintain contact with a plane in fixed body. This joint has three degrees ...
A condyloid joint is a modified ball and socket joint that allows primary movement within two perpendicular axes, passive or secondary movement may occur on a third axes. Some classifications make a distinction between condyloid and ellipsoid joints; [ 5 ] [ 6 ] these joints allow flexion, extension, abduction, and adduction movements ...
The shoulder joint also known as the glenohumeral joint is a synovial ball and socket joint. The shoulder joint involves articulation between the glenoid cavity of the scapula (shoulder blade) and the head of the upper arm bone ( humerus ) and functions as a diarthrosis and multiaxial joint.
In an automobile, ball joints are spherical bearings that connect the control arms to the steering knuckles. They are used on virtually every automobile made [4] and work similarly to the ball-and-socket design of the human hip joint. [5] A ball joint consists of a bearing stud and socket enclosed in a casing; all these parts are made of steel ...
Is a ball-and-socket joint. Proximal radioulnar joint: head of the radius: radial notch of the ulna: In any position of flexion or extension, the radius, carrying the hand with it, can be rotated in it. This movement includes pronation and supination.
Radiocarpal joint and metacarpophalangeal joint are examples of condyloid joints. An example of an Ellipsoid joint is the wrist; it functions similarly to the ball and socket joint except is unable to rotate 360 degrees; it prohibits axial rotation.
