What is Linea Semilunaris?
Linea Semilunaris is an anatomical feature of rectus abdominis, a large superficial muscle of abdomen. This almost vertical line, which was found on both sides of the muscle, indicates the side or outer boundary of the rectus of the abdomen, where it meets the outer and inner oblique muscles on both sides. It results from the cartilage that connects to the ninth rib to the sternum or breast bone and continues to the hair of tubercle, which is the bone of the pubis in the pelvis. Linea semilunaris acquires its name from the fact that the line curves slightly around each segment of the rectus abdomen, a muscle division that gives it the nickname of the "six -" "muscle. This muscle covers only a little more than half the width of the torso, with wrapping the side of the abdomen. It gets its distinguishing shape with several lines bordering or crossing the muscle abdomen.
Linea album runs down in the middle of the muscle and divides it into two longitudinal sections. Linea Semilunaris flows down on both sides of the muscle and separates it from the oblique. Three Spring inscriptions or fiber lengthsEN similar tendons pass muscle laterally and divide them into four sections on both sides from top to bottom. When it is exposed, the muscle actually resembles an "octagonal".
As the outer boundary of rectus abdominis, linea semilunaris is distinguished from reddish fibers of muscle abdomen in its white color. The reason is its composition not muscle fibers, but rather about aponeurous fibers. Aponeurosis consists of the same fibrous tissue based on collagen, which forms ligaments and tendons, but rather than being shaped as a belt or rope, it is as a wide flat leaf of tissue. Each layer of muscle in the abdomen is closed and is therefore separated from the other muscles by the housing of this tissue and it is the intersection of aponeurosis of the rectus of the abdomen, inner oblique and outer clouds, which form Linea Semilunar.
outer and inner oblique forms a superficial and deep layer of muscle that has been found on both sides of rectUS Belly. Where the surface surface of the inner oblique muscle meets the deep surface of the outer oblique muscle, the mixing of aponeurosis surrounds both muscles. The middle or internal boundaries of these aponeurosis are also mixed with the lateral or outer boundary of the rectus of the abdomen, resulting in a line of fibrous tissue with muscle fibers on both sides - this is Linea Semilunaris.
