Peritoneum coverings
❑The spleen is (intraperitoneal/retroperitoneal?)
❑ligaments of the spleen:———
❑——— Lig. Prevent downward movement of the spleen towards the left iliac fossa.
Peritoneum coverings

the peritoneum
❑gastrosplenic & lienorenal ligaments
N.B:
❑Phrenicocolic Lig. Prevent downward movement of the spleen towards the left iliac fossa.

Blood supply
❑It is supplied by the —— artery, the largest branch of the ———
❑It enters via the ——— ligament to reach near the hilum of the spleen,
❑where it breaks up into 5 or more branches, which goes into the spleen via its ——- to supply it
Blood supply
❑It is supplied by the splenic artery, the largest branch of the coeliac trunk
❑It enters via the lienorenal ligament to reach near the hilum of the spleen,
❑where it breaks up into 5 or more branches, which goes into the spleen via its hilum to supply it
The splenic vein runs a straight course from left to right behind the———
Its tributaries are:———
❑Lymphatic vessels drain into the ——— lymph nodes, and ultimately the —— nodes.
❑Innervation: ———
The splenic vein runs a straight course from left to right behind the body of pancreas
Its tributaries are:
• Short gastric veins
• Left gastroepiploic vein. • Pancreatic veins
• Inferior mesenteric vein
❑Lymphatic vessels drain into the pancreaticosplenic lymph nodes, and ultimately the coeliac nodes.
❑Innervation: Coeliac plexus
Segment of the Spleen
❑The splenic artery inside the spleen normally supplied 2 branches- —— & ——
❑is there anastomose btw these branches?
❑Every branch supplied its own ——

❑The splenic artery inside the spleen normally supplied 2 branches- superior & inferior
❑No anastomose btw these branches
❑Every branch supplied its own section
Applied Anatomy
❑———: enlarged spleen or spleen enlargement
❑———: It is a surgery to remove the entire spleen
❑———: It is the occurrence of acute pain in the tip of the shoulder due to the presence of blood or other irritants in the peritoneal cavity when a person is lying down and the legs are elevated.
Applied Anatomy
❑Palpation of the spleen
❑Splenomegaly: enlarged spleen or spleen enlargement ❑Splenectomy: It is a surgery to remove the entire spleen
❑Kehr’s sign: It is the occurrence of acute pain in the tip of the shoulder due to the presence of blood or other irritants in the peritoneal cavity when a person is lying down and the legs are elevated. Kehr’s sign in the left shoulder is considered a classic symptom of a ruptured spleen.
