acromion

 [ah-kro´me-on]
the lateral extension of the spine of the scapula, forming the highest point of the shoulder. adj., adj acro´mial.
 Posterior (dorsal) surface of the scapula, showing the acromion. From Dorland's, 2000.

a·cro·mi·on

(ă-krō'mē-on), [TA] Avoid the misspelling achromion.
The lateral extension of the spine of the scapula that projects as a broad flattened process overhanging the glenoid fossa; it articulates with the clavicle and gives attachment to part of the deltoid muscles. Its lateral border is a palpable landmark ("the point of the shoulder").
Synonym(s): acromial process

acromion

[əkrō′mē·ən]
Etymology: Gk, akron + omos, shoulder
the lateral extension of the spine of the scapula, forming the highest point of the shoulder and connecting with the clavicle at a small oval surface in the middle of the spine. It gives attachment to the deltoid and trapezius muscles. Also called acromion process. Compare coracoid process. acromial, adj.

Acromion

The flattened lateral, vaguely triangular projection of the spine of the scapula that forms the highest point of the shoulder and articulates with the clavicle. The acromion forms the point of attachment for the trapezius and deltoid muscles; medially, the acromion articulates with the lateral end of the clavicle, immediately behind the attachment of the coracoacromial ligament, the latter of which, in conjunction with the acromion and the coracoid process, forms an arch over the glenohumeral joint, preventing its upward dislocation and limiting the upward rotation of the humerus. The acromion is recognised by its thickened lateral border, which is a palpable subcutaneous mass.

ac·ro·mi·on

(ă-krō'mē-on) [TA]
The lateral 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 parts of the deltoid and trapezius muscles.
Synonym(s): acromial process.
[G. akrōmion, fr. akron, tip, + ōmos, shoulder]

acromion

the ventral prolongation of the spine of the shoulder blade or SCAPULA.

acromion
