Fascia Umbilical

The umbilical fascia is a connective tissue membrane located on the anterior abdominal wall. This zone is a direct continuation of the external oblique abdominal muscle. This fascia is found in all living organisms. But only in mammals does it perform a connecting function in the navel projection area. This type of fascia is also called hernial. It is a hollow round shell filled with fibrous tissue, formed as a result of fixation of the walls of the oblique muscle sheaths with the help of connective tissue. Depending on the direction of the fibers of the fascia, several varieties are distinguished. The simplest of them is transverse. Its fibers are located across the muscle fibers. The muscular-fascial zone, which is more complex in shape, consists of two layers. The outer layer is represented by fibers of the long oblique muscle. The inner layer is filled with fibers of the flat braid tuft and transverse abdominal muscle.

The fascia is limited anteriorly by the anterior edge of the rectus muscle and is intersected anteriorly by the diaphyseal fibers, which form the white sheet. Permeated with venous and lymphatic vessels, as well as a layer of fiber underneath, including the aponeurosis of the longitudinal muscle. This layer, tightly adjacent to the body, consists of connective, nervous and adipose tissue. Posteriorly it is attached to the posterior border of the rectus muscle
