If you ever break your humerus — a humeral fracture — your provider might use some of these terms to describe where your bone was damaged. How big is the humerus? Other than the bones in your legs, your humerus is the largest bone in your body.

The humeral upper extremity consists of a rounded head, a narrow neck, and two short processes (tubercles, sometimes called tuberosities). The body is cylindrical in its upper portion, and more prismatic below.

Oct 30, 2023 · The long tendon of the biceps brachii and an ascending branch of the anterior circumflex humeral artery are located within the sulcus. The sulcus consists of a lateral lip and a medial lip . The tendon of the pectoralis major muscle attaches on to the lateral lip (a.k.a. crest of greater tubercle), while the teres major tendon attaches on to ...

Aug 7, 2023 · The humeral head articulates with the glenoid fossa of the scapula and forms the glenohumeral joint, a synovial ball and socket joint.

Jan 28, 2025 · At the shoulder, the humeral head forms a ball-and-socket joint with the scapula (glenohumeral joint), enabling multi-directional movement of the arm. At the elbow, the humerus articulates with the radius and ulna, allowing flexion, extension, and rotation of the forearm.

Sep 26, 2024 · The humeral head makes up a portion of the ball-and-socket shoulder joint. This type of joint is the most versatile in the body, allowing for all degrees of motion. This area also serves as the insertion point for muscles that make up the shoulder girdle.

Aug 11, 2021 · The humeral head makes up a portion of the ball-and-socket shoulder joint, which is the insertion point for muscles making up the shoulder girdle. Several ligaments present in this area assist with securing the musculature. They also provide motion to the shoulder joint.

Jan 6, 2025 · These muscles originate on the scapula and insert on the humeral head, allowing for a large range of motion in the shoulder. The proximal humerus is the part of the bone closest to the shoulder joint and is most prone to fracture.

Oct 29, 2024 · On the lateral side of the humeral shaft is a roughened surface where the deltoid muscle attaches. This is known is as the deltoid tuberosity . The radial (or spiral) groove is a shallow depression that runs diagonally down the posterior surface of the humerus, parallel to the deltoid tuberosity.

Feb 28, 2022 · The humerus bone is located in the upper arm between the elbow and shoulder. It’s the longest bone in the arm, and supports movement in the arm and shoulder.
