The anterior left first rib refers to the first rib on the left side of the body, which is the uppermost rib in the rib cage. It plays a crucial role in protecting the thoracic cavity and supporting the shoulder girdle. The first rib is shorter and broader than the other ribs and has unique anatomical features, such as grooves for blood vessels and muscles. Its positioning is significant in various medical assessments and procedures, including those involving the brachial plexus and subclavian vessels.

The sternum and rib cage are medial to the breast.
The anterior end of the eighth rib attaches to the costal cartilage, which connects it to the sternum. Specifically, it typically articulates with the costal cartilage of the seventh rib, contributing to the formation of the costal margin. This attachment allows for some flexibility and movement of the ribcage during respiration.
The scalenus anterior and the scalenus medius all insert into the first rib (the scalenus posterior inserts into the second rib). They originate from cervical vertebrae two to cervical vertebrae seven (C2 - C7). Each of the scalene muscles has several points of origin, which look like fingers from your spine.
