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.
Runs laterally over the coracoid process and under the deltoideus, to which it gives branches; it then pierces that muscle and ends on the acromion in an arterial network formed by branches from the transverse scapular (a.k.a. suprascapular), thoracoacromial, and posterior humeral circumflex arteries. Clavicular branch
[1] [2] These supporting structures attach to the clavicle, humerus, and scapula, the latter providing the glenoid cavity, acromion and coracoid processes. The main joint of the shoulder is the shoulder joint (or glenohumeral joint), between the humerus and the glenoid process of the scapular. [1]
One action the scapula performs during a throwing or serving motion is elevation of the acromion process in order to avoid impingement of the rotator cuff tendons. [8] If the scapula fails to properly elevate the acromion, impingement may occur during the cocking and acceleration phase of an overhead activity.
One definition of a controlled process is an intentionally-initiated sequence of cognitive activities. [6] In other words, when attention is required for a task, we are consciously aware and in control. Controlled processes require us to think about situations, evaluate and make decisions. An example would be reading this article.
In anatomy, a process (Latin: processus) is a projection or outgrowth of tissue from a larger body. [1] For instance, in a vertebra, a process may serve for muscle attachment and leverage (as in the case of the transverse and spinous processes), or to fit (forming a synovial joint), with another vertebra (as in the case of the articular processes). [2]
Clavicular facet of scapula is small oval facet on the medial border of the acromion for articulation with the acromial facet on the lateral end of the clavicle. [1] Also called Clavicular articular facet of acromion. The coracoacromial ligament is attached near the clavicular facet. [2]
