The humerus is a long, slender bone that extends from the forearm to the elbow. The ulna is the medial bone of the forearm, running parallel to the radius. The proximal end of the ulna is the coronoid process, which is formed by a small rounded bump at the end. The trochlear notch articulates with the trochlea of the hilar head at the proximal end of the femur. The distal end of the olecranon is the radial notch of the ulna.
The humerus is composed of four bones: the scaphoid, triquetrum, lunate, and scapular. Each of these bones is attached to the articular capsule at its distal part. The anatomical neck extends from the triquetrum to the shaft of the humerus. The clavicular, glenoid, and scapular nerves are all situated in the lateral area of the humerus.
The humerus has three distinct anatomical regions. The humerus’s articular portion is modified and wider transversely. It articulates with the ulna and radius at the elbow joint. The capitulum and trochlea, located at the distal end of the trochlea, attach to the head of the ulna and the radius.
The humerus has three distinct parts, including the articular portion and the non-articular portion. The humerus’s articular portion is an extension of a condyle and extends transversely to the scapula. Its trochlea, or pulley-shaped surface, is found at the distal end.
The articular part of the humerus has two parts. The articular part is modified by a thin, transversely extending condyle. The trochlea is a pulley-shaped structure that articulates with the ulna and radius. Its lateral end is connected to the trochlea. Its trochlea forms the elbow joint.
The humerus is the only bone in the arm. It articulates with the radius and ulna bones of the forearm to form the elbow joint. In addition, the humerus is the most commonly fractured part of the humerus. The eminences are at the elbow’s head, and it has an asymmetrical neck and posterior circumflex artery.
The humerus has a true anatomical neck, and a surgical neck is the constriction below the greater and lesser tubercles. The neck of the humerus is the main focus of surgical operations. Anatomical features of the hammer are described in a section of the humerus and the surrounding structures. The radia and ulna are separated by the glenoid fossa.
The humerus is a single bone that forms the elbow joint. The humerus articulates with the ulna and radius bones of the forearm, which form the elbow joint. The humerus is the main bone of the arm. Its structure allows the arm to move. The humerus is divided into three parts: the anatomical neck of the humerus.
The humerus has a true anatomical neck, which is located between the humerus head and the greater and lesser tubercles of the forearm. The neck is a common fracture site. The axillary nerve and the posterior circumflex artery are protected by the neck. The radial sulcus is the main ligament that connects the humerus to the scapular bones.
The anteromedial surface of the humerus is a region between the medial border of the humerus and the crest of the greater tubercle. It is a little less extensive than the anterolateral surface. The anteromedial surface is narrow and concave from above to below. It gives the origin of the brachialis muscle.
The medial epicondyle is the prominent bony projection on the medial side of the humerus. The lateral epicondyle is on the lateral side of the humerus. Both have spiral grooves, and they give the humerus a distinct shape. The axillary nerve and radial artery are the major structures of the arm.
