In anatomy, the abdominal wall represents the boundaries of the abdominal cavity.The abdominal wall is split into the anterolateral and posterior walls. [1]There is a common set of layers covering and forming all the walls: the deepest being the visceral peritoneum, which covers many of the abdominal organs (most of the large and small intestines, for example), and the parietal peritoneum ...
A colostomy is an opening in the large intestine (colon), or the surgical procedure that creates one. The opening is formed by drawing the healthy end of the colon through an incision in the anterior abdominal wall and suturing it into place.
The linea alba is formed by the union of aponeuroses (of the muscles of the anterior abdominal wall [2]) that collectively make up the rectus sheath. The linea alba attaches to the xiphoid process superiorly, and to the pubic symphysis inferiorly. It is narrow inferiorly where the two recti abdominis muscles are in contact with each other ...
If a mass is present, the incision is made over the mass. Otherwise, the incision is made over McBurney's point (one-third of the way from the anterior superior iliac spine to the umbilicus), which represents the most common position of the base of the appendix. [9] The various layers of the abdominal wall are opened.
When the diaphragm contracts, it pulls the lower wall of the chest cavity down, increasing the volume of the lungs which then fill with air. Conversely, when the internal obliques contract they compress the organs of the abdomen, pushing them up into the diaphragm which intrudes back into the chest cavity reducing the volume of the air-filled ...
It is the incision of choice for Cesarean section and for abdominal hysterectomy for benign disease. A variation of this incision is the Maylard incision in which the rectus abdominis muscles are sectioned transversally to permit wider access to the pelvis. [7] This was pioneered by the Scottish surgeon Alfred Ernest Maylard (1855–1947) in ...
The arcuate line of rectus sheath (the arcuate line or the semicircular line of Douglas) is a line of demarcation [1] corresponding to the free inferior margin of the posterior layer of the rectus sheath [2] inferior to which only the anterior layer of the rectus sheath is present [3] and the rectus abdominis muscle is therefore in direct contact with the transversalis fascia.

A Pfannenstiel incision / ˈ f ɑː n ɪ n ʃ t iː l /, Kerr incision, Pfannenstiel-Kerr incision [1] or pubic incision is a type of abdominal surgical incision that allows access to the abdomen.
