Saddle joints are said to be biaxial, [5] allowing movement in the sagittal and frontal planes. [2] Examples of saddle joints in the human body include the carpometacarpal joint of the thumb, [6] [7] the sternoclavicular joint of the thorax, [8] the incudomalleolar joint of the middle ear, [9] and the calcaneocuboid joint of the heel.

Saddle joints, where the two surfaces are reciprocally concave/convex in shape, which resemble a saddle, permit the same movements as the condyloid joints but allows greater movement. Ball and socket joints "universal Joint" shoulder (glenohumeral) and hip joints These allow for all movements except gliding Compound joints [7] [8] / bicondyloid ...
The TMC joint is a synovial joint between the trapezium bone of the wrist and the metacarpal bone at the base of the thumb. This joint is a so-called saddle joint (articulatio sellaris), unlike the CMC joints of the other four fingers which are ellipsoid joints. [17] This means that the surfaces of the TMC joint are both concave and convex.
Heterocoelous vertebrae allow flexibility while preventing rotation. Procoelous and opisthocoelous centra form concavo-convex (ball and socket) joints, where the convex end, the condyle, fits into the concave end, the cotyle (also: cotyla). This configuration allows for greater stability without restricting mobility.
A joint, or articulation is the region where adjacent bones contact each other, for example the elbow, shoulder, or costovertebral joint. Terms that refer to joints include: articular process, referring to a projection that contacts an adjacent bone. suture, referring to an articulation between cranial bones.
In animal anatomy, a pivot joint (trochoid joint, rotary joint or lateral ginglymus) is a type of synovial joint whose movement axis is parallel to the long axis of the proximal bone, which typically has a convex articular surface.
