Anatomical terms of bone

The lateral epicondyle of the femur , smaller and less prominent than the medial epicondyle, gives attachment to the fibular collateral ligament of the knee-joint. Directly below it is a small depression from which a smooth well-marked groove curves obliquely upward and backward to the posterior extremity of the condyle.

Humerus Long bone of the upper arm

The humerus is a long bone in the arm that runs from the shoulder to the elbow. It connects the scapula and the two bones of the lower arm, the radius and ulna, and consists of three sections. The humeral upper extremity consists of a rounded head, a narrow neck, and two short processes. The body is cylindrical in its upper portion, and more prismatic below. The lower extremity consists of 2 epicondyles, 2 processes, and 3 fossae. As well as its true anatomical neck, the constriction below the greater and lesser tubercles of the humerus is referred to as its surgical neck due to its tendency to fracture, thus often becoming the focus of surgeons.

Ulnar nerve Nerve which runs near the ulna bone

In human anatomy, the ulnar nerve is a nerve that runs near the ulna bone. The ulnar collateral ligament of elbow joint is in relation with the ulnar nerve. The nerve is the largest in the human body unprotected by muscle or bone, so injury is common. This nerve is directly connected to the little finger, and the adjacent half of the ring finger, innervating the palmar aspect of these fingers, including both front and back of the tips, perhaps as far back as the fingernail beds.

Ulnar collateral ligament of elbow joint Ligament on the elbow

The ulnar collateral ligament (UCL) or internal lateral ligament is a thick triangular ligament at the medial aspect of the elbow uniting the distal aspect of the humerus to the proximal aspect of the ulna.

Cubital tunnel

The cubital tunnel is a space of the dorsal medial elbow which allows passage of the ulnar nerve around the elbow. It is bordered medially by the medial epicondyle of the humerus, laterally by the olecranon process of the ulna and the tendinous arch joining the humeral and ulnar heads of the flexor carpi ulnaris. The roof of the cubital tunnel is elastic and formed by a myofascial trilaminar retinaculum.

Cubital fossa

The cubital fossa,chelidon, or elbow pit is the triangular area on the anterior side of the upper limb between the arm and forearm of a human or other hominid animals. It lies anteriorly to the elbow when in standard anatomical position.

Lateral epicondyle of the humerus Structure of humerus

The lateral epicondyle of the humerus is a large, tuberculated eminence, curved a little forward, and giving attachment to the radial collateral ligament of the elbow joint, and to a tendon common to the origin of the supinator and some of the extensor muscles. Specifically, these extensor muscles include the anconeus muscle, the supinator, extensor carpi radialis brevis, extensor digitorum, extensor digiti minimi, and extensor carpi ulnaris. In birds, where the arm is somewhat rotated compared to other tetrapods, it is termed dorsal epicondyle of the humerus. In comparative anatomy, the term ectepicondyle is sometimes used.

Trochlea of humerus Articular surface of the elbow joint which articulates with the trochlear notch of the ulna

In the human arm, the humeral trochlea is the medial portion of the articular surface of the elbow joint which articulates with the trochlear notch on the ulna in the forearm.

Inferior ulnar collateral artery

The inferior ulnar collateral artery is an artery in the arm. It arises about 5 cm. above the elbow from the brachial artery.

Superior ulnar collateral artery Artery

The superior ulnar collateral artery, of small size, arises from the brachial artery a little below the middle of the arm; it frequently springs from the upper part of the a. profunda brachii.

Deep artery of arm

The deep artery of arm is a large vessel which arises from the lateral and posterior part of the brachial artery, just below the lower border of the teres major.

Lower extremity of femur

The lower extremity of femur is the lower end of the femur in human and other animals, closer to the knee. It is larger than the upper extremity of femur, is somewhat cuboid in form, but its transverse diameter is greater than its antero-posterior; it consists of two oblong eminences known as the lateral condyle and medial condyle.

Medial epicondyle of the humerus Rounded eminence on the medial side of the humerus

The medial epicondyle of the humerus is an epicondyle of the humerus bone of the upper arm in humans. It is larger and more prominent than the lateral epicondyle and is directed slightly more posteriorly in the anatomical position. In birds, where the arm is somewhat rotated compared to other tetrapods, it is called the ventral epicondyle of the humerus. In comparative anatomy, the more neutral term entepicondyle is used.

Medial epicondyle of the femur

The medial epicondyle of the femur is an epicondyle, a bony protrusion, located on the medial side of the femur at its distal end.

Interosseous recurrent artery

The interosseous recurrent artery is an artery of the forearm which arises from the posterior interosseous artery near its origin. It ascends to the interval between the lateral epicondyle and olecranon, on or through the fibers of the supinator but beneath the anconeus. It anastomoses with the middle collateral artery.

The brachial fascia is continuous with that covering the deltoideus and the pectoralis major muscle, by means of which it is attached, above, to the clavicle, acromion, and spine of the scapula; it forms a thin, loose, membranous sheath for the muscles of the arm, and sends septa between them; it is composed of fibers disposed in a circular or spiral direction, and connected together by vertical and oblique fibers.

Fascial compartments of arm Anatomical compartments

The fascial compartments of arm refers to the specific anatomical term of the compartments within the upper segment of the upper limb of the body. The upper limb is divided into two segments, the arm and the forearm. Each of these segments is further divided into two compartments which are formed by deep fascia – tough connective tissue septa (walls). Each compartment encloses specific muscles and nerves.

Humeroulnar joint

The humeroulnar joint, is part of the elbow-joint. It is composed of two bones, the humerus and ulna, and is the junction between the trochlear notch of ulna and the trochlea of humerus. It is classified as a simple hinge-joint, which allows for movements of flexion, extension and circumduction. Owing to the obliquity of the trochlea of the humerus, this movement does not take place in the antero-posterior plane of the body of the humerus.

The arcuate popliteal ligament is an extracapsular ligament of the knee. It is Y-shaped and is attached to the posterior portion of the head of the fibula. From there it goes to its two insertions; the medial one goes over popliteus muscle and blends with the oblique popliteal ligament, the lateral one to the Lateral epicondyle of the femur and blends there with the lateral head of gastrocnemius muscle.

Elbow Joint between the upper and lower parts of the arm

The elbow is the visible joint between the upper and lower parts of the arm. It includes prominent landmarks such as the olecranon, the elbow pit, the lateral and medial epicondyles, and the elbow joint. The elbow joint is the synovial hinge joint between the humerus in the upper arm and the radius and ulna in the forearm which allows the forearm and hand to be moved towards and away from the body.

Anatomical terms of bone

Many anatomical terms descriptive of bone are defined in anatomical terminology, and are often derived from Greek and Latin.
