    A hernia that exits the abdominal cavity directly through the deep layers of the abdominal wall, thereby bypassing the inguinal canal, is known as a direct inguinal hernia. In males with strong presentation of the cremasteric reflex , the testes can—during supine sexual activity or manual manipulation—partially or fully retract into the ...

    en.wikipedia.org/wiki/Quadrants_and_regions_of...

    The human abdomen is divided into quadrants and regions by anatomists and physicians for the purposes of study, diagnosis, and treatment. [1] [2] The division into four quadrants allows the localisation of pain and tenderness, scars, lumps, and other items of interest, narrowing in on which organs and tissues may be involved.

    The transversalis fascia (or transverse fascia) is the fascial lining of the anterolateral abdominal wall [1] [2] situated between the inner surface of the transverse abdominal muscle, and the preperitoneal fascia. [3] [2] It is directly continuous with the iliac fascia, [2] the internal spermatic fascia, [citation needed] and pelvic fascia. [2]

  7. Abdominal muscles - Wikipedia

    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 .

  8. Colostomy - Wikipedia

    en.wikipedia.org/wiki/Colostomy

  9. Inguinal ligament - Wikipedia

    en.wikipedia.org/wiki/Inguinal_ligament

    The inguinal ligament runs from the anterior superior iliac crest of the ilium to the pubic tubercle of the pubic bone. It is formed by the external abdominal oblique aponeurosis and is continuous with the fascia lata of the thigh. There is some dispute over the attachments. [3] Structures that pass deep to the inguinal ligament include:
