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 ...
The lateral umbilical fold is an elevation (on either side of the body) of the peritoneum lining the inner/posterior surface of the lower anterior abdominal wall formed by the underlying inferior epigastric artery and inferior epigastric vein which the peritoneum covers.
Abdominal muscles cover the anterior and lateral abdominal region and meet at the anterior midline. These muscles of the anterolateral abdominal wall can be divided into four groups: the external obliques , the internal obliques , the transversus abdominis , and the rectus abdominis .
The lateral border of the rectus sheath is part of the recently described EIT ambivium to more precisely describe this important part of the anterior abdominal wall. [1] The EIT ambivium is formed by the Musculus Obliquus Externus (MO E ), the Musculus Obliquus Internus (MO I ) and the Musculus Transversus Abdominis ( T A).
The transverse abdominal muscle (TVA), also known as the transverse abdominis, transversalis muscle and transversus abdominis muscle, is a muscle layer of the anterior and lateral (front and side) abdominal wall, deep to (layered below) the internal oblique muscle. It is thought by most fitness instructors to be a significant component of the core.
In human anatomy, the inguinal triangle is a region of the abdominal wall. ... Medial border: Lateral margin of the rectus sheath. [1] [2]
In vertebrates, the abdomen is a large body cavity enclosed by the abdominal muscles, at the front and to the sides, and by part of the vertebral column at the back. Lower ribs can also enclose ventral and lateral walls. The abdominal cavity is continuous with, and above, the pelvic cavity. It is attached to the thoracic cavity by the diaphragm.
The lateral inguinal fossa is a structure described in human anatomy. It is a shallow concave stretch of peritoneum on the deep surface of the anterior abdominal wall and is best seen from the greater peritoneal cavity, looking anteriorly (as, for example, during laparoscopy).
