Inguinal Ring Preperitoneal

Preperitoneal inguinal ring: anatomy and functions

The preperitoneal inguinal ring, also known as the anulus inguinalis praeperitonealis or JNA, is one of the most important anatomical structures in the groin area. This ring is located in the anterior abdominal wall and plays a key role in maintaining normal anatomy and function of the genitourinary system.

Anatomy of the preperitoneal inguinal ring

The preperitoneal inguinal ring is located in the groin area, under the upper part of the rectus abdominis muscle. The ring is an opening in the anterior abdominal wall through which the spermatic cord and the round connected ligament of the uterus pass.

The ring has the shape of an oval ring, the size of which may vary depending on gender and age. In women, the preperitoneal inguinal ring is usually smaller than in men, but its anatomical features and functions remain approximately the same.

Functions of the preperitoneal inguinal ring

The preperitoneal inguinal ring plays an important role in maintaining the normal anatomy and function of the genitourinary system. It represents the boundary between the internal and external inguinal rings, which are formed by the muscles and ligaments of the abdominal wall.

The ring also serves as an important support point for the spermatic cord and the round connective ligament of the uterus. These structures pass through the preperitoneal inguinal ring and connect the genitourinary system with the abdominal cavity.

In addition, the preperitoneal inguinal ring is important for the diagnosis and treatment of inguinal hernia. A hernia occurs when internal organs extend beyond the abdominal cavity and pass through the inguinal ring. In this case, the hernia can only be treated through surgery.

Conclusion

The preperitoneal inguinal ring is an important anatomical formation in the groin area. It plays a key role in maintaining normal anatomy and function of the genitourinary system, and is also an important fulcrum for the spermatic cord and round ligament of the uterus. Understanding the anatomy and function of the preperitoneal inguinal ring is important for the diagnosis and treatment of inguinal hernia.
