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.
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 (circumduction).
Examples of a pivot joint include: Proximal radioulnar joint; Distal radioulnar joint; Median atlanto-axial joint; In contrast, spherical joints (or ball and socket joints) such as the hip joint permit rotation and all other directional movement, while pivot joints only permit rotation.
A saddle joint (sellar joint, [1] [2] articulation by reciprocal reception [citation needed]) is a type of synovial joint in which the opposing surfaces are reciprocally concave and convex. It is found in the thumb , the thorax , the middle ear , and the heel .
These joints are of the condyloid kind, formed by the reception of the rounded heads of the metacarpal bones into shallow cavities on the proximal ends of the proximal phalanges. [1] Being condyloid, they allow the movements of flexion, extension, abduction, adduction and circumduction (see anatomical terms of motion) at the joint. [1]
The atlanto-occipital joint (Articulatio atlantooccipitalis) is an articulation between the atlas bone and the occipital bone. It consists of a pair of condyloid joints. It is a synovial joint .
A condyle (/ ˈ k ɒ n d ɪ l,-d aɪ l /; [1] [2] Latin: condylus, from Greek: kondylos; κόνδυλος knuckle) is the round prominence at the end of a bone, most often part of a joint – an articulation with another bone. It is one of the markings or features of bones, and can refer to: On the femur, in the knee joint: Medial condyle ...
The condyloid process or condylar process is the process on the human and other mammalian species' mandibles that ends in a condyle, the mandibular condyle.It is thicker than the coronoid process of the mandible and consists of two portions: the condyle and the constricted portion which supports it, the neck.
