30 Οκτ 2023 · The humerus is the longest and largest bone of the upper limb. It consists of a proximal end, a shaft and a distal end, all which contain important anatomical landmarks. The humerus articulates with the scapula proximally at the glenohumeral joint so it participates in the movements of the shoulder.
Humerus. The articular surface of the humeral head points in a medial, posterior and slightly caudal direction and is separated from the major and minor tuberosities by its anatomical neck. When the arm is hanging down the side with its anterior aspect facing the body, the greater tuberosity lies laterally and . the lesser tuberosity anteriorly.
17 Δεκ 2018 · The humerus is the largest bone of the upper extremity and defines the human brachium (arm). It articulates proximally with the glenoid via the glenohumeral (GH) joint, and distally with the...
We’re going to be looking at a humerus from the right arm (pictured above), with the anterior (or front) view on the left, and the posterior (or back) view on the right. Head – Let’s start with the ball-shaped section at the proximal end (or top) of the humerus, which is called the head.
Humerus: The olecranon fossa should be on the posterior side and distal (farther away from the shoulder joint. This is where the olecranon process of the ulna fits in when the elbow is straightened. Make sure the head of the humerus is placed medially. Below is the posterior view of a right humerus. Figure \(\PageIndex{3}\)
The AP view of the humerus is part of the humerus series and is usually taken in a standing position. However, it can also be obtained in a supine position. The projection demonstrates the humerus in its natural anatomical position allowing for adequate radiographic examination of the entire humerus and its respective articulations. Indications.
7 Αυγ 2023 · Posterior compartment muscles: The triceps brachii muscle contains three heads, with the medial head originating on the posterior aspect of the humerus, inferior to the spiral groove, and the lateral head originating on the posterior surface, both insert into the olecranon process of the ulna and allow extension of the forearm at the elbow ...
