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 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 ...
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 ...
The 90-90 rotates your hips—a ball-and-socket joint—side to side and stretches muscles like your adductors and glutes. If your hips feel stiff or, worse yet, hurt, you will be limited in what ...
In an automobile, ball joints are spherical bearings that connect the control arms to the steering knuckles, and are used on virtually every automobile made. [1] They bionically resemble the ball-and-socket joints found in most tetrapod animals. [2] A ball joint consists of a bearing stud and socket enclosed in a casing; all these parts are ...
The shoulder joint is a ball-and-socket joint between the scapula and the humerus. The socket of the glenoid fossa of the scapula is itself quite shallow, but it is made deeper by the addition of the glenoid labrum. The glenoid labrum is a ring of cartilaginous fibre attached to the circumference of the cavity.
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 and functions as a diarthrosis and multiaxial joint.
The incudostapedial joint is a small, synovial ball-and-socket joint between the incus (anvil) and the stapes (stirrup). The joint's function is to transfer vibrations between the two ossicles. The incudostapedial joint lies between the long leg of the incus (long crus, or crus longum incudis) and the head of the stapes (caput stapedis). [1]
