==Types of Peritoneum==
==Types of Peritoneum==
The peritoneum doubles up to form the following suspensory structures:
*Mesentry: attaches viscera to the dorsal abdominal wall.
*Mesentery: from viscera to the dorsal abdominal wall.
*Omentum: from the stomach to other viscera.
*Omentum: from the stomach to other viscera.
*Ligament: from viscera not involved in digestion to the abdominal wall ''or'' to other viscera that are not involved in digestion (e.g.ligaments of the [[Liver - Anatomy & Physiology|liver]]).
*Ligament: from viscera not involved in digestion to the abdominal wall ''or'' to other viscera that are not involved in digestion (e.g.ligaments of the [[Liver - Anatomy & Physiology|liver]]).
===Mesenteries===
*The entire alimetary tract is attached to the dorsal body wall by mesentery, a derivative of the dorsal mesogastrium.
**'''Mesoduodenum''' from the duodenum to the abdominal roof. Contains the right lobe of the pancreas.
**'''Great Mesentery''' from the jejunum and ileum to the abdominal roof. Contains the cranial abdominal artery and vein, mesenteric lymph nodes and mesenteric plexus.
**'''Mesocolon''' from the colon to the abdominal roof.
**'''Mesorectum''' from the rectum to the abdominal roof.
*The female reproductive tract is also suspended by peritoneal derivatives.
**'''Broad Ligament''' consisting of mesometrium, mesosalpinx and mesovarium. From ovary, oviduct, uterus, cervix and cranial vagina to the dorsal body wall. Contains ovarian artery, uterine branch of the ovarian artery, uterine artery, ovarian vein, uterine vein and uterine lymph node (mare).
===Omenta===
*During development in the region of the stomach, a fold of the dorsal mesogastrium becomes extended into a curtain - like structure called the '''greater omentum'''.
**Originates from the greater curvature of the stomach and attaches to the proximal part of the duodenum.
**Potential space between the two sheets is called the omental bursa.
**Covers the jejunal mass on the ventral abdominal wall.
**Opening to the omental bursa is called the epiploic foramen.
*The '''lesser omentum''' runs from the lesser curvature of the stomach to the liver.
===Ligaments===
*'''Gastrophrenic Ligament''' - from the greater curvature of the stomach to the crura of the diaphragm.
*'''Gastrosplenic Ligament''' - part of the greater omentum. Connects the spleen to the stomach.
*'''Nephrosplenic Ligament''' (renosplenic ligament) - In the horse - from spleen to left kidney.
*'''Round Ligament''' - part of the broad ligament. From the ovary to the inguinal ring.
*'''Suspensory Ligament''' - from the ovary to the abdominal wall.
*'''Proper Ligament of the ovary''' - from the ovary to the oviduct.
*Ligaments of the [[Liver - Anatomy & Physiology| Liver]]
