The arcuate line is concave inferior-wards. [2] The arcuate line is visible upon the inner surface of the abdominal wall. [1] The arcuate line may be a well-defined, [1] [2] or may be represented by a gradual waning of the aponeurotic fibres with concomitant increasing prominence of the transversalis fascia. [2]
Below the arcuate line: Below this level, the aponeuroses of all three muscles (including the transversus) pass in front of the rectus. [2] [3] The posterior layer of the rectus sheath is thus absent and the rectus abdominis muscle is separated from the peritoneum only by the transversalis fascia. [2]
In anatomy, an arcuate line is any structure that is curvilinear. Arcuate line (anterior abdominal wall) , a term from human abdominal anatomy Arcuate line (ilium) , the inner edge of the pelvis
The linea terminalis or innominate line consists of the pubic crest, pectineal line (pecten pubis), the arcuate line, the sacral ala, and the sacral promontory. [ 1 ] It is the pelvic brim , which is the edge of the pelvic inlet .
Below it there is a smooth, rounded border, the arcuate line, which runs anterior, inferior, and medial. When the "left" or "right" adjective is used (e.g. "right iliac fossa"), the iliac fossa usually means one of the inguinal regions of the nine regions of the abdomen.
Superiorly, the lateral umbilical fold ends where the vessels reach and enter the rectus sheath [1] at the arcuate line of rectus sheath; in spite of the name, the lateral umbilical folds do not extend as far superiorly as the umbilicus. [2] Inferiorly, it extends to just medial to the deep inguinal ring. [citation needed]
A Spigelian is the type of ventral hernia where aponeurotic fascia pushes through a hole in the junction of the linea semilunaris and the arcuate line, creating a bulge.It appears in the lower quadrant of the abdomen between an area of dense fibrous tissue and abdominal wall muscles causing a (Spigelian aponeurosis).
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 ...
