Acromial region
Regio acromialis
- Related terms: Acromial region (Scapular region)
Definition
The acromial region corresponds to the lateral area of the shoulder centered on the acromion, a bony process located at the distal end of the scapular spine. It is an important anatomical landmark situated at the junction between the scapula and the proximal part of the arm.
Anatomically, this region includes the distal scapular spine and the acromion, as well as the insertion or attachment of several muscles (deltoide, omotransverse, trapezius).
The acromion is well developed in the dog, cat, ruminants, and humans, but it is absent in the horse, which alters the lateral contour of the shoulder and the configuration of the deltoid muscle in this species.
