Anatomical terminology

The superior ulnar collateral artery (inferior profunda 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.

Contents

It pierces the medial intermuscular septum, and descends on the surface of the medial head of the Triceps brachii to the space between the medial epicondyle and olecranon, accompanied by the ulnar nerve, and ends under the Flexor carpi ulnaris by anastomosing with the posterior ulnar recurrent, and inferior ulnar collateral.

It sometimes sends a branch in front of the medial epicondyle, to anastomose with the anterior ulnar recurrent.

Arm Proximal part of the free upper limb between the shoulder and the elbow

In human anatomy, the arm is the part of the upper limb between the glenohumeral joint and the elbow joint. In common usage, the arm extends through the hand. It can be divided into the upper arm, which extends from the shoulder to the elbow, the forearm which extends from the elbow to the hand, and the hand. Anatomically the shoulder girdle with bones and corresponding muscles is by definition a part of the arm. The Latin term brachium may refer to either the arm as a whole or to the upper arm on its own.

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.

Brachial artery Large blood vessel

The brachial artery is the major blood vessel of the (upper) arm. It is the continuation of the axillary artery beyond the lower margin of teres major muscle. It continues down the ventral surface of the arm until it reaches the cubital fossa at the elbow. It then divides into the radial and ulnar arteries which run down the forearm. In some individuals, the bifurcation occurs much earlier and the ulnar and radial arteries extend through the upper arm. The pulse of the brachial artery is palpable on the anterior aspect of the elbow, medial to the tendon of the biceps, and, with the use of a stethoscope and sphygmomanometer, often used to measure the blood pressure.

Median nerve Nerve of the upper limb

The median nerve is a nerve in humans and other animals in the upper limb. It is one of the five main nerves originating from the brachial plexus.

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.

Upper limb

The upper limbs or upper extremities are the forelimbs of an upright-postured tetrapod vertebrate, extending from the scapulae and clavicles down to and including the digits, including all the musculatures and ligaments involved with the shoulder, elbow, wrist and knuckle joints. In humans, each upper limb is divided into the arm, forearm and hand, and is primarily used for climbing, lifting and manipulating objects.

Cubital fossa

The cubital fossa,chelidon, or elbow pit is the triangular area on the anterior view of the elbow of a human or other hominid animal. It lies anteriorly to the elbow when in standard anatomical position.

Ulnar artery Artery of the forearm

The ulnar artery is the main blood vessel, with oxygenated blood, of the medial aspects of the forearm. It arises from the brachial artery and terminates in the superficial palmar arch, which joins with the superficial branch of the radial artery. It is palpable on the anterior and medial aspect of the wrist.

The pronator teres is a muscle that, along with the pronator quadratus, serves to pronate the forearm. It has two attachments, to the medial humeral supracondylar ridge and the ulnar tuberosity, and inserts near the middle of the radius.

Posterior interosseous artery

The posterior interosseous artery is an artery of the forearm. It is a branch of the common interosseous artery, which is a branch of the ulnar artery.

Medial cutaneous nerve of forearm

The medial cutaneous nerve of the forearm branches from the medial cord of the brachial plexus. It contains axons from the ventral rami of the eighth cervical (C8) and first thoracic (T1) nerves.

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.

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.

Posterior ulnar recurrent artery

The posterior ulnar recurrent artery is an artery in the forearm. It is one of two recurrent arteries that arises from the ulnar artery, the other being the anterior ulnar recurrent artery. The posterior ulnar recurrent artery being much larger than the anterior and also arises somewhat lower than it.

Anterior ulnar recurrent artery

The anterior ulnar recurrent artery is an artery in the forearm. It is one of two recurrent arteries that arises from the ulnar artery, the other being the posterior ulnar recurrent artery.

In anatomy, arterial tree is used to refer to all arteries and/or the branching pattern of the arteries. This article regards the human arterial tree. Starting from the aorta:

Radial collateral artery

The radial collateral artery is a branch of the deep brachial artery. It arises in the arm proper and anastomoses with the radial recurrent artery near the elbow.

Medial collateral artery

The medial collateral artery is a branch of profunda brachii artery that descends in the middle head of the triceps brachii and assists in forming the anastomosis with the interosseous recurrent artery above the olecranon of the ulna near the elbow.

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.

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.
