Anatomy Almost cylindrical head of ulna articulates with ulnar notch of radius, distal radioulnar joint. A pivot joint; movement is rotation of radius (and hand; ulna main contributor to elbow joint, radius to wrist joint) around the ulnar head. Clinical Radial head is proximal and articulates with a notch on the ulna (proximal radioulnar joint

Anatomy Course A terminal branch of the profunda brachii artery, that originates whilst the profunda brachii is travelling in the radial groove of the humerus. It descends close to the bone on the lateral aspect of the arm, and joins with the radial recurrent artery at the elbow joint. Supply Contributes to the blood supply

Anatomy Attaches from the radial styloid process, passing to the waist and distal pole of the scaphoid bone. Functions Provides static stability to the wrist and carpal joints. Interested in taking our award-winning Pocket Anatomy app for a test drive?

Anatomy Attaches from the lateral epicondyle of the humerus, annular ligament and the supinator crest of the ulna. Functions Provides lateral static stability to the elbow joint. Interested in taking our award-winning Pocket Anatomy app for a test drive?

Anatomy Course The radial nerve arises from the posterior cord of the brachial plexus, and is the largest terminal branch of the posterior cord. It exits the axilla by passing through the triangle made by the border of the long head of the triceps, the humerus and the inferior margin of the teres major. It

Anatomy Course A branch of the radial artery, originating in the forearm, near the radial tuberosity. It ascends between the brachioradialis and supinator muscles over the lateral epicondyle to join with the radial collateral artery. Supply The radial recurrent artery contributes to the blood supply of the elbow joint, and the muscles on the lateral

Anatomy Course Originates from the superficial palmar arch and winds up around the wrist, passing lateral to the flexor carpi radialis tendon. It runs along the lateral aspect of the forearm, passing deep to the brachioradialis. It joins with the ulnar vein to become the brachial vein. Drain Drains the lateral hand and forearm. Interested

Anatomy Attaches to the palmar surface of the radial styloid process. Runs across the scaphoid and attaches to the medial palmar surface of the capitate. Functions Provides static stability to the wrist and carpal joints. Interested in taking our award-winning Pocket Anatomy app for a test drive?

Anatomy Origin: Transverse processes of L3 to L5, iliolumbar ligament and iliac crest. Insertion: Inferior border of 12th rib and transverse processes of L1 to L3. Key relations: -Quadratus lumborum lies deep to the colon, kidney, psoas major, psoas minor and the diaphragm. -The subcostal, iliohypogastric and ilioinguinal nerveslie anterior to the fascia that overlies

Anatomy Course Originates from the brachial artery at the head of the radius, in the cubital fossa at the elbow. It runs along the lateral aspect of the forearm, passing deep to the brachioradialis muscle, running with a superficial branch of the radial nerve. It passes lateral to the flexor carpi radialis tendon and winds
