Triangular space

Triangular Space

The Triangular Space (pronunciation: /traɪˈæŋɡjʊlər speɪs/) is a specific anatomical term used in the field of medicine to describe a particular region in the human body.

Etymology

The term "Triangular Space" is derived from the Latin words "triangulum" meaning "triangle" and "spatium" meaning "space". It is so named due to its triangular shape.

Definition

The Triangular Space is a small anatomical space located in the axilla, or armpit. It is bordered by the teres major muscle inferiorly, the teres minor muscle superiorly, and the long head of the triceps brachii muscle medially.

Clinical Significance

The Triangular Space is clinically significant as it allows for the passage of the circumflex scapular artery, a branch of the subscapular artery. This artery supplies blood to the muscles and bones in the shoulder region. Any injury or disease affecting this space can potentially disrupt the blood supply and cause serious health issues.
