The abdominal cavity is the space lined with the intra-abdominal fascia. The abdominal cavity is bounded in front and from the side by the anterolateral abdominal wall, and behind by the posterior abdominal wall. Its upper limit is the diaphragm; its lower border is the end line of the pelvis. The abdominal cavity consists of the abdominal organs and the retroperitoneal space.
7.1. TOPOGRAPHIC ANATOMY OF ANTEROLATERAL ABDOMINAL WALL
Borders. Above it is bordered by the right costal arch, the xiphoid process of the sternum and the left costal arch. The bottom is bordered by the inguinal folds and the upper edge of the symphysis pubis. The lateral borders are represented by a continuation of the mid-axillary line and a vertical line from the lower point of the tenth rib to the iliac crest.
The anterolateral abdominal wall is divided into three parts by two horizontal lines. The upper horizontal line connects the low points of the edge arcs. The lower horizontal line connects the anterior superior iliac spines. The result is the epigastric, gastric, and hypogastric sections of the anterolateral abdominal wall. Two vertical lines drawn on the lateral borders of the rectus abdominis muscles divide each section into three areas. The epigastric region is divided into the right hypochondriac region, the left hypochondriac region, and the epigastric region proper. The stomach compartment is divided into right and left lateral and umbilical regions. The sublingual region is divided into the right groin, the left groin, and the suprapubic region.
