Artery of the Superior Segment

The artery of the upper segment (lat. a. segmenti superioris) is a large artery that passes through the upper part of the human body and provides blood supply to the upper limb and head. It is a branch of the common carotid artery and is located in the neck, above the level of the collarbone.

The superior segment artery begins from the common carotid artery at the level of the neck and passes through the neck, shoulder and arm to the hand. Along its path, it is divided into several branches that provide blood supply to the head, neck, shoulder girdle and upper limb.

One of the main branches of the artery of the upper segment is the brachial artery (a. brachialis), which passes through the shoulder and provides blood supply to the muscles, bones and skin of the upper limb. In addition, the superior segment artery also supplies blood to the muscles, nerves, and blood vessels of the head and neck.

An important aspect of the functioning of the upper segment artery is its regulation. It is regulated by various mechanisms such as blood pressure, oxygen and nutrient levels in the blood, and other factors. Dysregulation of the upper segment artery can lead to various diseases such as stroke, myocardial infarction and other cardiovascular diseases.

Thus, the superior segment artery plays an important role in providing blood supply to the upper part of the human body. Its regulation and functioning are of great importance for human health and the prevention of various diseases.
