DELTOID EMINENCE Meaning and
Definition
-
The deltoid eminence refers to a prominent and well-defined ridge on the lateral aspect (outer side) of the upper arm, just below the shoulder joint. Anatomically, it is a landmark that mainly represents the deltoid muscle, the largest muscle of the shoulder. The deltoid eminence is formed by the thick, fleshy belly of the deltoid muscle, which gives the upper arm a rounded appearance.
The deltoid muscle originates from the clavicle (collarbone), scapula (shoulder blade), and acromion process (a bony projection on the scapula). It inserts into the deltoid tuberosity of the humerus (upper arm bone). The deltoid eminence becomes more prominent when the muscle contracts, giving the upper arm a well-rounded appearance.
The deltoid muscle acts to abduct (move away from the body) the arm, allowing for lifting the arm sideways. It is involved in several movements of the shoulder joint, including flexion, extension, and rotation. The deltoid eminence is a vital anatomical landmark for health professionals, especially during physical examinations, as it can provide valuable information about muscle development, strength, and any potential injuries or abnormalities affecting the deltoid muscle. It is also relevant in aesthetic medicine, as individuals often strive for a well-developed and symmetrical deltoid eminence to enhance the visual appearance of their upper arm.

Etymology of DELTOID EMINENCE
