Anatomy Area on medial side of ulna. Attachments: part of brachoradialis, oblique cord (ligament, other end attaches just below radial tuberosity). Interested in taking our award-winning Pocket Anatomy app for a test drive?

Anatomy Course A branch of the brachial artery. It travels along the medial side of the arm. It runs deep in the arm, running along the flexor digitorum profundus muscle for the most of its course. It becomes most medial about halfway down the ulna. It enters the hand just lateral to the pisiform bone,

Anatomy Origin: The trigeminal motor nucleus is located in the mid pons tegmentum and the trigeminal sensory nucleus extends the length of the brain stem and upper cervical cord. Its subnuclei include the principal sensory nucleus located in the pontine tegmentum, the mesencephalic nucleus extending into the midbrain and the spinal nucleus extending through the

Anatomy Small finger side of nearer row of carpal bones, pyramidal shape. Articulates out with lunate, down with hamate, in front (palmar) with pisiform. On ulnar side but does not articulate with it. Clinical The palmar (anterior) aspect of the carpus is concave and, covered with the flexor retinaculum (ligament), forms the carpal tunnel. Interested

Anatomy Separated from olecranon by trochlear notch, sits in coronoid fossa of humerus, just above trochlea, when elbow bent (elbow flexed). The radial notch is at its lateral edge. Attachments; brachialis, parts of flexor digitorum superficialis and profundus, pronator teres, sometimes flexor pollicis longus. Interested in taking our award-winning Pocket Anatomy app for a test

Anatomy Articulates down with articular disc between it and wrist joint, and laterally with the ulnar notch of the radius (pivot joint). Interested in taking our award-winning Pocket Anatomy app for a test drive?

Anatomy Curved bulge upper end ulna, sits, when elbow extended, in olecranon fossa at back of bottom of humerus, lending significant bony strength, stability and movement limitation (stopping hyperextension). Attachments; triceps brachii, posterior and ulnar collateral ligaments. Clinical Back of olecranon process covered by bursa, just subcutaneous; bursitis in trauma, infection, pressure, rheumatoid arthritis, gout.

Anatomy The radial head articulates with (rolls over) the radial notch of ulna, manifest as pronation and supination. At the lower end of the forearm, the ulnar head articulates with the ulnar notch of the radial head. Clinical Radial head is proximal and articulates with a notch on the ulna; ulnar head is distal and

Anatomy Thumb side, further row of carpal bones, between scaphoid and 1st metacarpal, has deep palmar groove for flexor carpi radialis. Attachments; origin opponens pollicis, and abductor, flexor pollicis brevis, transverse carpal ligament. The saddle-shaped surface articulating with 1st meta-carpal allows large range of thumb movement including opposition. Clinical Often removed in treatment of basal

Anatomy Above 2nd metacarpal in further row of carpal bones, wedge-shaped, narrow end palmar. Articulates up with scaphoid, down with 2nd metacarpal, in with capitate, out with trapezium. Least injured carpal bone. Clinical “Sam Likes To Play; Try To Catch Him”. S, L, T, P, proximal row; T, T, C, H; distal row, lateral (thumb)
