The ellipsoid joint also has two types of movement but allows opposition movement only to a small degree. Its surfaces are ovoid and vary in both length and curvature as they are traced from front to back or from side to side, just ...
ellipsoid joint: a synovial joint in which a condyle is received into an elliptic cavity, as the wrist joint. A condyloid joint permits no axial rotation but allows flexion, extension, adduction, abduction, and circumduction. Also called condyloid joint. Compare ball-and-socket joint, pivot joint, saddle joint . See also joint .
joint [joint] the site of the junction or union of two or more bones of the body; its primary function is to provide motion and flexibility to the frame of the body. Some are immovable, such as the sutures where segments of bone are fused together in the skull. Others, such as those between the vertebrae, are gliding joints and have limited motion ...
A condyloid joint (also called condylar, ellipsoidal, or bicondylar) is an ovoid articular surface, or condyle that is received into an elliptical cavity. This permits movement in two planes, allowing flexion, extension, adduction, abduction, and circumduction. Examples. Examples include: the wrist-joint; metacarpophalangeal joints
Ellipsoidal joints, such as the joint at the base of your index finger, allow bending and extending, rocking from side to side, but rotation is limited.
Joint - Joint - The synovial fluid: The main features of synovial fluid are: (1) Chemically, it is a dialyzate (a material subjected to dialysis) of blood plasma—that is, the portion of the plasma that has filtered through a membrane—but it contains a larger amount of hyaluronic acid than other plasma dialyzates.
Condyloid joints consist of an oval-shaped end of one bone fitting into a similarly oval-shaped hollow of another bone (Figure 5). This is also sometimes called an ellipsoidal joint. This type of joint allows angular movement along two axes, as seen in the joints of the wrist and fingers, which can move both side to side and up and down.
gliding joints (plane joints) hinge joint. Joint between bones (as at the elbow or knee) that permits motion in only one plane. pivot joint. rotating bone turns around an axis; i.e. connection between radius/ulna and humerus. saddle joint. type of joint found at the base of each thumb; allows grasping and rotation.
