Tuberositas costae secundae is a Latin term used in anatomy to describe a specific anatomical feature. It refers to the secondary tuberosity of the rib, which is a prominent bony prominence located on the posterior aspect of the rib. This tuberosity is situated towards the anterior end of the rib, near the angle or the junction between the body and the costal cartilage.
The tuberositas costae secundae serves as a site for the attachment of various muscles, ligaments, and tendons. It provides stability and support to the rib by allowing these structures to anchor to it. Attachment of these structures to the tuberosity helps to protect and enclose vital organs, such as the heart and lungs, while still allowing for mobility and breathing.
The tuberosity may vary in size and prominence among individuals, and it can be palpated or felt by applying pressure along the back or side of the ribcage. Understanding the location and significance of the tuberositas costae secundae is important in clinical settings, such as in surgical procedures or when assessing and diagnosing rib-related injuries or conditions.
In summary, the tuberositas costae secundae refers to a bony prominence on the posterior aspect of a rib, providing attachment sites for muscles and ligaments and contributing to the stability and protection of the ribcage.
Tuberosity of the second rib a rough oval area, about the middle of the outer surface and lower border of the rib, for the attachment of the serratus magnus muscle.
