The spine grows taller and thicker as it moves laterally and superiorly toward the shoulder joint. At the far end of the spine, the acromion forms where the bone widens significantly and extends anteriorly to cover the superior aspect of the shoulder joint.
Where does the acromion attach?
The Acromion and the Coracoid Processes The acromion process is attached to the scapular spine, and it works with the coracoid process of the scapula to form a solid and stable shoulder joint.
Where do the shoulders connect to the spine?
The shoulder blade is divided into a small upper and larger lower surface by a ridge called the scapular spine. This ridge runs straight across the shoulder blade, forming the “roof” of the shoulder (the acromion) at one end. The shoulder socket (glenoid) is located on the side edge of the shoulder blade.
Where is the acromion in the shoulder?
Acromion. The roof (highest point) of the shoulder that is formed by a part of the scapula.
Where is the acromion on the shoulder?
The acromion is the bony tip of the outer edge of your shoulder blade (scapula) that comes off the top of the back side of this bone. It meets with the end of your collar bone (clavicle) at your shoulder. Shoulder impingement occurs when the tendon rubs against the acromion.
What does acromion mean?

What muscle lies under acromion?
supraspinatus muscle
The supraspinatus muscle originates and sits in the supraspinatus fossa of the scapular. The muscle passes as a tendon under the acromion, where its is separated from the bone by a subacromial bursa and then passes over the glenohumeral joint and inserts on the superior facet of the greater tubercle.
Is the acromion part of the scapula?
The shoulder is made up of two joints, the acromioclavicular joint and the glenohumeral joint. The acromioclavicular joint is where the acromion, part of the shoulder blade (scapula) and the collar bone (clavicle) meet.

|---|---|
| Extends off of the spine of the scapula | Lies below the acromion and in front of the spine |
| Forms the top part of the shoulder joint | Forms the front part of the shoulder joint |
