Tuberosity Of The Ulna

	Tuberosity Of The Ulna The tuberosity of the ulna is a rough eminence on the proximal end of the ulna. It occurs at the junction of the antero-inferior surface of the coronoid process with the front of the body. It provides an insertion point to a tendon of the brachialis (the oblique cord The oblique cord is a ligament between the ulnar and radius bones in the forearm near the elbow. It takes the form of a small, flattened band, extending downward and lateralward, from the lateral side of the Tuberosity of the ulna, ulnar tuberosity ... of the brachialis is attached to the lateral border).

	Coronoid Process Of The Ulna The coronoid process of the ulna is a triangular process projecting forward from the anterior proximal portion of the ulna. Structure Its ''base'' is continuous with the body of the bone, and of considerable strength. Anatomy Its ''apex'' is pointed, slightly curved upward, and in flexion of the forearm is received into the coronoid fossa of the humerus. Its ''upper surface'' is smooth, convex, and forms the lower part of the semilunar notch. Its ''antero-inferior'' surface is concave, and marked by a rough impression for the insertion of the brachialis muscle. At the junction of this surface with the front of the body is a rough eminence, the tuberosity of the ulna, which gives insertion to a part of the brachialis; to the lateral border of this tuberosity the oblique cord is attached. Its ''lateral surface'' presents a narrow, oblong, articular depression, the radial notch. Its ''medial surface'', by its prominent, free margin, serves for the attachment of part of the uln ...

	Brachialis The brachialis (brachialis anticus), also known as the Teichmann muscle, is a muscle in the upper arm that flexes the elbow. It lies deeper than the biceps brachii, and makes up part of the floor of the region known as the cubital fossa (elbow pit). The brachialis is the prime mover of elbow flexion generating about 50% more power than the biceps.Saladin, Kenneth S, Stephen J. Sullivan, and Christina A. Gan. Anatomy & Physiology: The Unity of Form and Function. 2015. Print. Structure The brachialis originates from the anterior surface of the distal half of the humerus, near the insertion of the deltoid muscle, which it embraces by two angular processes. Its origin extends below to within 2.5 cm of the margin of the articular surface of the humerus at the elbow joint. Its fibers converge to a thick tendon, which is inserted into the tuberosity of the ulna and the rough depression on the anterior surface of the coronoid process of the ulna.

	Oblique Cord The oblique cord is a ligament between the ulnar and radius bones in the forearm near the elbow. It takes the form of a small, flattened band, extending downward and lateralward, from the lateral side of the Tuberosity of the ulna, ulnar tuberosity at the base of the coronoid process of the ulna, coronoid process to the radius a little below the radial tuberosity. Its fibers run in the opposite direction to those of the Interosseous membrane of the forearm. It is called by other names including oblique ligament, chorda obliqua, radio-ulnar ligament, chorda oblique antebrachii anterior, proximal interosseous band, dorsal oblique accessory cord, proximal band of the interosseous membrane, superior oblique ligament, oblique ligament proper, round ligament, and ligament of Josias Weitbrecht, Weitbrecht. It has no known function and can be cut without apparent consequence. Structure A study upon the arms of 38 people found that its mean length is 3.4 cm (range 2.4 to 4.2 cm) ...
