Anatomy Of Elbow Joint

The orientation of the bones forming the elbow joint produces a hinge type synovial joint which allows for extension and flexion of the forearm. The anatomy of the elbow.

Elbow Joint

The elbow is where the two bones of the forearm the radius on the thumb side of the arm and the ulna on the pinky finger side meet the bone of the upper arm the humerus.

Anatomy of elbow joint. The ends of the bones are covered with cartilage. The muscles comprising the contour of the medial anterior forearm include the pronator teres flexor carpi radialis palmaris longus and flexor carpi ulnaris. Cartilage has a rubbery consistency that allows the joints to slide easily against one another and absorb shock.

Brachialis acts exclusively as an elbow flexor and is one of the few muscles in. Anatomy of the elbow the elbow is a hinge joint made up of the humerus ulna and radius. The elbow is a hinged joint made up of three bones the humerus ulna and radius.

Movements at a hinge joint biceps brachii originates as two heads. The elbow joint is a complex hinge joint formed between the distal end of the humerus in the upper arm and the proximal ends of the ulna and radius in the forearm. Anatomy of the elbow joint.

Brachioradialis acts essentially as an elbow flexor but also supinates during extreme pronation. The elbow joint has a synovial membranelined joint capsule that is contiguous between the hinge and radioulnar aspects of the joint. The elbow allows for the flexion and extension of the forearm relative to the upper arm as well as rotation of the forearm and wrist.

There are two muscles in this compartment that produce flexion at the elbow joint. The unique positioning and interaction of the bones in the joint allows for a small amount of rotation as well as hinge action. There are three main flexor muscles at the elbow.

Brachialis originates from the distal half of the anterior surface of the humerus. Henry has demonstrated that their relationship and location can be approximated by placing the opposing thumb and the index long. Biceps brachii is the main elbow flexor but as a biarticular.

The synovial lining covers the internal surface of the fibrous joint capsule and the nonarticular surfaces of the joint that are located intracapsularly. An inside look at the structure of the elbow. Flexion brachialis biceps brachii brachioradialis.

The elbow is one of the largest joints in the body. In conjunction with the shoulder joint and wrist the elbow gives the arm much of its versatility as well as structure and durability. The bones are held together with ligaments that form the joint capsule.

Extension triceps brachii and anconeus.
