In human anatomy, the acromion (from Greek: akros, "highest", ōmos, "shoulder", pl.: acromia) is a bony process on the scapula (shoulder blade). Together with the coracoid process, it extends laterally over the shoulder joint. The acromion is a continuation of the scapular spine, and hooks over anteriorly.
The medial border (also called the vertebral border or medial margin) is the longest of the three borders, and extends from the superior angle to the inferior angle. [8] In animals it is referred to as the dorsal border. Four muscles attach to the medial border. Serratus anterior has a long attachment on the anterior lip.

The root of the spine of the scapula is the most medial part of the scapular spine. It is termed "triangular area of the spine of scapula", based on its triangular shape giving it distinguishable visible shape on x-ray images. [1] The root of the spine is on a level with the tip of the spinous process of the third thoracic vertebra. [2]
They are inserted into the medial margin of the acromion, and into the superior lip of the posterior border of the spine of the scapula. The inferior or lower (or ascending) fibers of the trapezius arise from the spinous processes of the remaining thoracic vertebrae (T4–T12).

A food safety expert weighs in on flour bugs, also known as weevils, that can infest your pantry after one TikToker found her flour infested with the crawlers.
The osseous margins of the coraco-acromial arch and hence the supraspinatus outlet canal; The shape of the acromion; This projection has a low tolerance for errors and, accordingly, needs proper execution. [26] The Y-projection can be traced back to Wijnblath’s 1933 published cavitas-en-face projection. [27]
