  2. Rectus sheath - Wikipedia

    en.wikipedia.org/wiki/Rectus_sheath

    The rectus sheath (also called the rectus fascia [1]) is a tough fibrous compartment formed by the aponeuroses of the transverse abdominal muscle, and the internal and external oblique muscles. It contains the rectus abdominis and pyramidalis muscles, as well as vessels and nerves.

  3. Arcuate line of rectus sheath - Wikipedia

    en.wikipedia.org/wiki/Arcuate_line_of_rectus_sheath

    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. [1]

  5. Linea alba (abdomen) - Wikipedia

    en.wikipedia.org/wiki/Linea_alba_(abdomen)

    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 ...

  7. Abdominal wall - Wikipedia

    en.wikipedia.org/wiki/Abdominal_wall

    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 ...

  8. Rectus abdominis muscle - Wikipedia

    en.wikipedia.org/wiki/Rectus_abdominis_muscle

    The rectus abdominis has many sources of arterial blood supply. Classification of the vascular anatomy of muscles: First, the inferior epigastric artery and vein (or veins) run superiorly on the posterior surface of the rectus abdominis, enter the rectus fascia at the arcuate line, and serve the lower part of

  9. Aponeurosis of the abdominal external oblique muscle

    en.wikipedia.org/wiki/Aponeurosis_of_the...

    The aponeurosis of the abdominal external oblique muscle is a thin but strong membranous structure, the fibers of which are directed downward and medially.. It is joined with that of the opposite muscle along the middle line, and covers the whole of the front of the abdomen; above, it is covered by and gives origin to the lower fibers of the pectoralis major; below, its fibers are closely ...
