Pronunciation: [akɹˈə͡ʊmi͡ən] (IPA) 
The word "acromion" is spelled with six letters, and the IPA phonetic transcription indicates how to pronounce the word: /əˈkroʊmiən/. The first three letters are pronounced as a schwa sound followed by "k" and "r" sounds. Then "o" and "m" sounds are used to form the middle of the word, and it ends with "i", "o", and "n" sounds. The word is used to describe the bony process on the scapula that articulates with the clavicle.
The acromion is a term primarily used in anatomy and physiology to describe a specific part of the human shoulder. It refers to a bony prominence located near the top of the scapula (shoulder blade), specifically on its lateral aspect. The acromion can be easily identified as the highest point of the shoulder when it is palpated laterally or by touching the top of the shoulder.
Anatomically, the acromion is an extension of the scapular spine, which projects laterally and superiorly. It forms an important connection between the scapula and the clavicle, thereby completing the bony framework of the shoulder joint. The acromion plays a crucial role in the overall stability and function of the shoulder. It serves as an attachment site for various ligaments and muscles, such as the deltoid muscle, which covers the shoulder joint and aids in its movement.
Additionally, the acromion can be classified into different types based on its shape, including type I (flat), type II (curved), and type III (hooked). These classifications help determine the susceptibility of an individual to shoulder conditions such as impingement syndrome or rotator cuff tears.
In summary, the acromion is the bony prominence located on the outer aspect of the shoulder blade. It is instrumental in connecting the scapula with the clavicle and serves as an attachment site for key ligaments and muscles involved in shoulder movement and stability.
Acromial process, the outer end of the spine of the scapula which projects as a broad flattened process overhanging the glenoid fossa; it articulates with the clavicle and gives attachment to the deltoid and some fibers of the trapezius.

The word "acromion" has its origins in Greek. It comes from the Greek word "akros", meaning "highest" or "topmost", combined with the word "ōmos", meaning "shoulder". Therefore, "acromion" refers to the highest point of the shoulder, specifically referring to the projection of the scapula (shoulder blade) that forms the acromioclavicular joint.
