What is a pivot joint?
Pivot joint, also called rotary joint, or trochoid joint, in vertebrate anatomy, a freely moveable joint (diarthrosis) that allows only rotary movement around a single axis. The moving bone rotates within a ring that is formed from a second bone and adjoining ligament.
Can you get bone cancer in your elbow?

What is the medical name for the elbow?
The outer bony prominence of the elbow is the lateral epicondyle, a part of the humerus bone. Tendons attached to this area can be injured, causing inflammation or tendonitis (lateral epicondylitis, or tennis elbow). The inner portion of the elbow is a bony prominence called the medial epicondyle of the humerus.
What is the function of the elbow?
The radius and ulna also meet one another in the elbow to permit a small amount of rotation of the forearm. The elbow therefore functions to move the arm like a hinge (forward and backward) and in rotation (outward and inward).
How does the human elbow work?
The elbow swings 180 degrees in one direction to extend the forearm, and it also helps turn the forearm at the point where the parallel bones in the forearm—the radius and ulna—meet. Joints are held together by a network of ligaments. Ligaments are made of tough, flexible connective tissue.
What is a synovial joint?
A synovial joint is the type of joint found between bones that move against each other, such as the joints of the limbs (e.g. shoulder, hip, elbow and knee). … synovial membrane (or synovium) – a special layer of cells that lines the joint capsule and produces the synovial fluid.
Is the elbow a ball and socket joint?
Hinge joints, such as the elbow and knee, limit movement in only one direction so that the angle between bones can increase or decrease at the joint. … The shoulder and hip joints form the only ball and socket joints in the body.
What bone is your elbow?
Your elbow is a joint made up of three bones: The humerus (upper arm bone) The radius (forearm bone on the thumb side) The ulna (forearm bone on the pinky side)
Is the elbow a synovial joint?
The Elbow Joint. The elbow is the joint connecting the upper arm to the forearm. It is classed as a hinge-type synovial joint.
What is the Humeroradial joint?
The humeroradial joint is the joint between the head of the radius and the capitulum of the humerus, is a limited ball-and-socket joint, hinge type of synovial joint.
