What bones meet together at the elbow?

What bones meet together at the elbow?

The elbow is a complex joint formed by the articulation of three bones –the humerus, radius and ulna. The elbow joint helps in bending or straightening of the arm to 180 degrees and assists in lifting or moving objects. The bones of the elbow are supported by: Ligaments and tendons.

What are elbow bones called?

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. The lower end of the humerus flares out into two rounded protrusions called epicondyles, where muscles attach.

How many bones are in the elbow?

The arm in the human body is made up of three bones that join together to form a hinge joint called the elbow.

What is above the elbow called?

The outside, or lateral, bump just above the elbow is called the lateral epicondyle. Most of the muscles that straighten the fingers and wrist all come together in one tendon to attach in this area.

Why does the bone next to my elbow hurt?

The bump on the outer side of the elbow is called the lateral epicondyle. Lateral epicondylitis is a condition that causes pain and tenderness at the prominence on the outer part of the elbow. The condition occurs as a result of overusing the forearm muscles that straighten and raise the hand and wrist.

What is the top of your elbow called?

The prominent part of the ulna, at the tip of the elbow, is called the olecranon. The elbow can bend (flex) and straighten (extend), but the joint between the top of the radius and the ulna called the proximal radioulnar joint is also involved in forearm rotation.

How does the humeroulnar joint move?

The two joints linking these bones—the humeroulnar and humeroradial joints—are hinge joints and are capable of flexion and extension of the elbow. Extension at the humeroulnar joint is the opposite of flexion and is the movement of the hand and forearm away from the shoulder.

Is a humeroulnar joint a synovial joint?

The first 2 are the ones traditionally thought of as constituting the elbow: the humeroulnar articulation (the synovial hinge joint with articulation between the trochlea of the humeral condyle and the trochlear notch of the ulna) and the humeroradial articulation (the articulation between the capitulum of the humeral …

What’s the inside of the elbow called?

Technically, you can refer to the area as the antecubital fossa. Antecubital is an adjective meaning “of or relating to the inner or front surface of the forearm” (in Latin ante means “before” and cubitum means “elbow”). Fossa is a Medieval Latin borrowing that is used for an anatomical pit, groove, or depression.

What muscle is above the elbow?

The triceps tendon is a tough, flexible tissue that attaches the triceps muscle at the back of the upper arm to the elbow bone. It helps triceps muscles to straighten your arm. Repeated strain on a tendon can cause tiny micro-tears in the tissue.

What is the upper part of my arm called?

The arm proper (brachium), sometimes called the upper arm, the region between the shoulder and the elbow, is composed of the humerus with the elbow joint at its distal end.

What bone joins the radius and ulna to the elbow?

Humerus: This long bone extends from the shoulder socket and joins the radius and ulna to form the elbow. Radius: This forearm bone runs from the elbow to the thumb side of the wrist. Ulna: This forearm bone runs from the elbow to the “pinkie” side of the wrist.

Where is the ulna bone located in the body?

Where is the Ulna Bone Located in the Human Body It is the medial bone of the forearm, located on the side opposite to the thumb, that is on the side of the little finger, extending from the region of the wrist to the elbow.

What is the anatomy of the elbow?

The Anatomy of the Elbow. The elbow is a hinged joint made up of three bones, the humerus, ulna, and radius. The ends of the bones are covered with cartilage. Cartilage has a rubbery consistency that allows the joints to slide easily against one another and absorb shock.

What does the head of the ulna articulate with?

The small rounded part on the distal ulnar surface is the head, and it articulates with the cup-shaped ulnar notch of the radius and the triangular fibrocartilage articular disc, a cartilage structure that keeps the ulna from forming any direct articulations with the carpal bones [7, 11].
