The pecten pubis, also known as the pectineal line, is the sharp ridge located on the superior ramus of the pubic bone.
Detailed Explanation
The pecten pubis serves as an important anatomical landmark in the pelvis. Here's a breakdown of its key features:
- Location: It forms the upper border of the superior pubic ramus.
- Origin: It starts behind the pubic tubercle.
- Course: It extends laterally and posteriorly behind the iliopubic eminence.
- Continuation: It merges with the arcuate line of the ilium, which is located on the inner surface of the ilium.
Significance
The pecten pubis is significant for several reasons:
- Muscle Attachment: It provides an attachment point for the pectineus muscle.
- Inguinal Ligament: It contributes to the formation of the inguinal ligament.
- Pelvic Brim: It forms part of the pelvic brim (also known as the linea terminalis), an important boundary separating the true pelvis from the false pelvis.
- Surgical Landmark: It is a crucial landmark during certain surgical procedures in the pelvic region.
In summary, the pecten pubis is a key anatomical feature of the pubic bone, serving as a point of muscle attachment, a component of important ligaments, and a vital landmark for both anatomical orientation and surgical planning.
