Medical Definition of Elbow The elbow is the joint where three long bones meet in the middle portion of the arm. The bone of the upper arm (humerus) meets the inner bone of the forearm (ulna) and the outer bone of the forearm (radius) to form a hinge joint.The radius and ulna also meet in the elbow to allow for rotation of the forearm.The elbow functions to move the arm like a hinge (forward and backward) and in rotation (twisting outward and inward). The biceps muscle is the major muscle that flexes the elbow hinge.he radius and ulna also meet in the elbow to allow for rotation of the forearm. The elbow functions to move the arm like a hinge (forward and backward) and in rotation (twisting outward and inward). The biceps muscle is the major muscle that flexes the elbow hinge.

- The elbow is a synovial hinge joint located between the upper arm and forearm. It is formed by the meeting of three bones: the humerus in the upper arm and the ulna and radius in the lower arm.Like all other hinge joints, the elbow permits movement in one plane, namely the flexion and extension of the forearm relative to the upper arm.he elbow is a synovial hinge joint located between the upper arm and forearm.

Medical Definition of Elbow, tip of the Elbow, tip of the: The bony tip of the elbow is called the olecranon. It is formed by the near end of the ulna, one of the two long bones in the forearm (the other is the radius).The triceps muscle tendon of the back of the arm attaches to the tip of the elbow (the olecranon). Diseases can affect the olecranon.For example, inflammation of the tiny fluid-filled sac (bursa) at the tip of the elbow van occur; it is referred to as olecranon bursitis.And also, for example, a firm nodule can form at the tip of the elbow; it is referred to as an olecranon nodule (and can be found in gout or rheumatoid arthritis).he triceps muscle tendon of the back of the arm attaches to the tip of the elbow (the olecranon).

Medical Definition of 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.

Is the elbow distal or proximal to the wrist? The elbow is proximal to the wrist but anatomy experts likely would not use the term that way. When talking about muscle attachments you might talk about the distal attachment of the brachioradialis muscle because there are two ends of the muscle and it is important to distinguish the muscle attachment points. dis·talˈdistl/ adjective ANATOMY.
