ball-and-sock·et joint

(bôl′ən-sŏk′ĭt)
n.
1. A synovial joint, such as the shoulder or hip joint, in which a spherical knob or knoblike part of one bone fits into a cavity or socket of another, so that some degree of rotary motion is possible in every direction. Also called enarthrosis.
2. A joint, as in a mechanical device, that permits rotary movement in all directions through the movement of a ball in a socket. Also called ball joint.

ball joint

n
1. (Mechanical Engineering) a coupling between two rods, tubes, etc, that consists of a spherical part fitting into a spherical socket, allowing free movement within a specific conical volume
2. (Anatomy) anatomy Also called: multiaxial joint a bony joint, such as the hip joint, in which a rounded head fits into a rounded cavity, allowing a wide range of movement

Because the cricoarytenoid joint is a multiaxial joint and cannot be completely visualized in a single slice, the presence of any variable needed to be identified on two or more planes.
The shoulder joint is less constrained joint due to large spherical head and small glenoid, the stability of the joint depends mostly on the capsule and the glenohumeral ligaments and the rotator cuff, biceps tendon and the force couple caused by the deltoid and the rotator cuff, unlike hip joint which is also multiaxial joint and very stable inherently; the shoulder is prone for dislocation and is at high risk of recurrent anterior dislocation, more so in athletes with overhead activity and anybody uses the shoulder for over the head activities.
