Examples of peritoneum in the following topics:

  • The Peritoneum

    • The peritoneum, the serous membrane that forms the lining of the abdominal cavity, covers most of the intra-abdominal organs.
    • The peritoneum is the serous membrane that forms the lining of the abdominal cavity or the coelom.
    • The outer layer, called the parietal peritoneum, is attached to the abdominal wall.
    • The term mesentery is often used to refer to a double layer of visceral peritoneum.
    • Differentiate among the digestive organs and their location relative to the peritoneum

  • Peritonitis

    • Peritonitis is an inflammation of the peritoneum, usually caused by an infectious organism that is introduced into the abdominal cavity.
    • Peritonitis is an inflammation of the peritoneum , the thin tissue that lines the inner wall of the abdomen and covers most of the abdominal organs.
    • Antibiotics are usually administered intravenously, but they may also be infused directly into the peritoneum.
    • The peritoneum, colored in blue, is the serous membrane that forms the lining of the abdominal cavity.
    • Peritonitis is an inflammation of the peritoneum often causing abdominal pain and tenderness.

  • Body Cavity Membranes

    • The mesothelium is a membrane that forms the lining of several body cavities: the pleura (thoracic cavity), peritoneum (abdominal cavity including the mesentery) and pericardium (heart sac).
    • The peritoneum is the serous membrane that forms the lining of the abdominal cavity or the coelom—it covers most of the intra-abdominal (or coelomic) organs—in amniotes and some invertebrates (annelids, for instance).
    • The peritoneum both supports the abdominal organs and serves as a conduit for their blood and lymph vessels and nerves.The abdominal cavity (the space bounded by the vertebrae, abdominal muscles, diaphragm and pelvic floor) should not be confused with the intraperitoneal space (located within the abdominal cavity, but wrapped in peritoneum).

  • Uterus

    • It is covered by a sheet-like fold of peritoneum, the broad ligament.
    • The perimetrium is the peritoneum covering of the fundus and ventral and dorsal aspects of the uterus.
    • Secondarily, it is supported by ligaments and the peritoneum (broad ligament of uterus).

  • Endometriosis

    • Endoscopic image of endometrial lesions at the peritoneum of the pelvic wall.

  • Body Cavities

    • The abdominopelvic cavity is lined by a type of mesothelium called the peritoneum.

  • Intercostal Nerves

    • The intercostal nerves are distributed chiefly to the thoracic pleura and abdominal peritoneum.

  • Location and External Anatomy of the Kidneys

    • They are considered retroperitoneal, which means that they lie behind the peritoneum, the membrane lining of the abdominal cavity.

  • Anatomy of the Large Intestine

    • Along the sides of the taeniae, tags of peritoneum filled with fat, called epiploic appendages (or appendices epiploicae) are found.

  • Histology of the Large Intestine

    • Along the sides of the taeniae are tags of peritoneum filled with fat; these are called epiploic appendages, or appendices epiploicae.
