ACROMIAL ARTERY Meaning and
Definition
-
The acromial artery is a small blood vessel that arises from the subclavian artery, which is a major artery originating from the aorta. The acromial artery is responsible for the blood supply to the acromion process, a prominent bony structure located on the superior aspect of the scapula (shoulder blade).
The acromial artery branches off the subclavian artery in the neck region, specifically near the clavicle. From there, it passes through the deltoid muscle of the shoulder and ascends towards the acromion process. Along its course, it gives off smaller branches that penetrate the muscles and tissues in the region, supplying them with oxygenated blood.
The acromial artery plays a crucial role in maintaining adequate blood supply to the acromion process and surrounding structures. This blood supply ensures the oxygen and nutrients required for cellular metabolism and tissue health, helping to support optimal function and wellbeing of the shoulder region. The acromial artery is an essential component of the overall circulatory system and is part of the network of vessels responsible for delivering blood to various parts of the body.
In case of injury or occlusion of the acromial artery, blood flow to the acromion process and surrounding tissues may be compromised, leading to reduced oxygenation and nutrition. This can potentially result in tissue damage or even necrosis if left untreated. Surgical or interventional procedures may be necessary to repair or bypass the acromial artery in such cases.
Etymology of ACROMIAL ARTERY
The word "acromial" is derived from the Latin word "acromion", which refers to the highest point of the shoulder. It is an anatomical term that is used to describe structures near or related to the acromion process of the scapula (shoulder blade).
The term "artery" also has Latin roots, derived from the Latin word "arteria", and ultimately from the Greek word "arteria", which means "windpipe" or "artery". In ancient times, arteries were believed to carry air or vital spirits, hence the connection to the term windpipe. Over time, the meaning shifted to refer to the vessels that carry blood, and "artery" came to be associated specifically with blood vessels. Therefore, when combined, "acromial artery" refers to an artery that is located near or associated with the acromion process of the scapula.
