Examples: Radiocarpal and Metacarpophalangeal joints. Joints that do not move are called "fixed." Other joints may move a little, such as the vertebrae. It allows flexion, extension, rotation, abduction, adduction and circumduction. Examples include: the wrist-joint; metacarpophalangeal joints; metatarsophalangeal joints . The condyloid joint occurs where an egg-shaped surface of a bone fits into a concavity in another bone. An example is the elbow joint.

The joint of the wrist that allows the palm of the hand to be turned up and down is also a pivot joint. 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 hinge joint permits flexion and extension with a limited degree of rotation. saddle: The shoulder and hip joints are examples of _____ joints. They are slightly movable (amphiarthrosis). This allows for a greater range of motion than hinge joints but does not allow complete rotation like ball and socket joints provide. Hinge. An example of when the ball and socket joint is used in sport is cricket. the shoulder and hip joints. (5) A saddle joint allows for flexion, extension, and other movements, but no rotation.

Ellipsoidal joints - Ellipsoidal joints, such as the wrist joint, allow all types of movement except pivotal movements. Some classifications make a distinction . This permits movement in two planes, allowing flexion, extension, adduction, abduction, and circumduction. Where the metacarpal meets the phalange is an example of a condyloid joint. Wrist, elbow, shoulder, ankle, knee, and hip . of ellipsoidal and saddle-shaped joints, and polyaxial movement, of spherical joints. ball-and-socket Two examples of pivot joints in your body are the pivot joint in your neck that .

An example of a pivot joint is the joint of the first and second vertebrae of the neck that allows the head to move back and forth. A condyloid joint (also called condylar, bicondylar, ellipsoid, or ellipsoidal) is an ovoid articular surface, or condyle, that is received into an elliptical cavity.
