  1. 1. PERITONEUMANDPERITONEALCAVITY
  2. 2. Hi Future Doctors  <3 This work took from my time and effort to improve my review method. As you know already, its really hard to open your Anatomy book + atlas + dictionary especially when you have only little time to finish a certain topic , especially when Your First language is not English. So I made this reviewer which is combined of all the three things I mentioned earlier So here it is now between your hands , I hope this will help you like how it helped me In return , all I need from you is your prayers for me and family ^_^ Thank you and God bless you ,, In this version I followed the BRS Anatomy 7e txt but the pictures was from different sources the sources were : Atlas of Human Anatomy, 6e – Netter | Grays Anatomy for Students 2e | McMinn's Seventh 7e | Clinically Oriented Anatomy - Moore 7e | And other pictures from google (sorry i wasn't able to get the exact site) please inform me if there is any suggestions or notes or errors in this file Here is my personal email address, feel free to contact me [ iamsami.md@gmail.com ] "Learning Medicine without understanding Can be torture, But with clear concepts it become Fun and pleasure”

Falciform Ligament ■ Is a sickle-shaped peritoneal fold connecting the liver to the diaphragm and the anterior abdominal wall. ■ Contains the ligamentum teres hepatis and the paraumbilical vein, which connects the left branch of the portal vein with the subcutaneous veins in the region of the umbilicus.
  28. 28. 3. Ligamentum Teres Hepatis (Round Ligament of the Liver) ■ Lies in the free margin of the falciform ligament and ascends from the umbilicus to the inferior (visceral) surface of the liver, lying in the fissure that forms the left boundary of the quadrate lobe of the liver. ■ Is formed after birth from the remnant of the left umbilical vein, which carries oxygenated blood from the placenta to the left branch of the portal vein in the fetus. (The right umbilical vein is obliterated during the embryonic period.)
  29. 29. 4. Coronary Ligament ■ Is a peritoneal reflection from the diaphragmatic surface of the liver onto the diaphragm and encloses a triangular area of the right lobe, the bare area of the liver. ■ Has right and left extensions that form the right and left triangular ligaments.

  36. 36. ■ Presents three recesses*: (a) superior recess, which lies behind the stomach, lesser omentum, and left lobe of the liver; (b) inferior recess, which lies behind the stomach, extending into the layers of the greater omentum (c) splenic recess, which extends to the left at the hilus of the spleen. recess * a small empty space, hollow, or cavity.
  37. 37. B. Greater Sac (Supracolic) ■ Extends across the entire breadth of the abdomen and from the diaphragm to the pelvic floor and presents numerous recesses into which pus from an abscess may be drained. 1.

  38. 38. 1. Subphrenic (Suprahepatic) Recess ■ Is a peritoneal pocket between the diaphragm and the anterior and superior part of the liver and is separated into right and left recesses by the falciform ligament. 2. Subhepatic Recess or Hepatorenal Recess (Morrison’s Pouch) ■ Is a deep peritoneal pocket between the liver anteriorly and the kidney and suprarenal gland posteriorly and communicates with the lesser sac via the epiploic foramen and the right paracolic gutter, thus the pelvic cavity. 3. Paracolic Recesses (Gutters) ■ Lie lateral to the ascending colon (right paracolic gutter) and lateral to the descending colon (left paracolic gutter).
  39. 39. C. Epiploic or Omental (Winslow’s) Foramen ■ Is a natural opening between the lesser and greater sacs. ■ Is bounded superiorly by peritoneum on the caudate lobe of the liver, inferiorly by peritoneum on the first part of the duodenum, anteriorly by the free edge of the lesser omentum, and posteriorly by peritoneum covering the IVC.
