ANATOMY OF SPLEEN.pptx #MBBS #BAMS #BHMS #

Anatomy is very important subject for medical faculty.
Anatomy of spleen is one of the important part or section from antomy.
In this presentation all the factors are explained very effectively.

3. SPLEEN INTRODUCTION : In latin spleen is called as LEIM. The spleen is the largest lymphoid organ of the body. The main function of the spleen is to filter blood by removing worn out RBC and microbes from circulation . Spleen manufacture RBC in fetal life and lymphocyte after birth. It also provide IgM by plsma cells to restoare RBC’S and release them when required in circulation.

4. WEDGED SHAPE ?

5. Spleen is a wedge shaped, dark purple color organ located mainly in the left hypochondrium and partly in the epigastrium. Spleen is wedged in between fundus of stomach and diaphragm behind mid-axillary line opposite to 9,10 and 11 rib. SIZE : Size of spleen is roughly corresponds to size of the fist of the subject or person. DIMENTION : Thickness – 1 inch ; Width – 3 inch Length -5 inch ; Weight- 7 ounce (210 gm) LOCATION :

6. EXTERNAL FEATURES : Spleen has 2End, 3Borders and 2 Surfaces

7. 2 END: Anterior end – It is broad and more like border. Posterior end- It is rounded and rest on the upper pole of the left kidney. 3 BORDERS : Superior border – It is thin and having two notches which are present near it’s anterior end. Intrmediate border- It is illdefined, passing through hilum. It separates the gastric impression from renal impression. Inferior border- It is concave and irregular. It separates the visceral surface from diaphragmatic surface from lower side.

8. 2 SURFACE : Diaphramatic surface – It is convex downward, irregular and also having presence of impression of ribs. It is directed upward, backward and to left. Diaphragm separates the spleen from left lung by left costo-diaphragmtic recess and 9 th 10th and 11 th ribs.

9. Visceral surface : The visceral sUrface is concave and irregular. Hilum- It lies between superior and intermediate borders. It pierce by branches and tributaries of splenic vessels.

10. VISCERAL RELATION : Presents 4 visceral impression-gastric, renal, colic and pancreatic etc. 1.Gastric impression - Produced by fundus of the stomach above the hilum of the spleen. 2.Renal impression- Produced by left kidney behind the hilum. 3.Colic impression- Produced by Left colic flexure in front of hilum. 4.Pancreatic impression: Produced by tail of pancreas at the hilum.

11. PERITONEAL RELATION : Spleen is completely enclosed in the peritoneum except at hilum. From where 2 peritoneal fold extend one on stomach and other on kidney are called as gastro-splenic ligament,lenorenal ligament. Phrenicocolic ligament is not attached to the spleen but Supports the anterior end.

12. BLOOD SUPPLY: By splenic artery Branches –pancreas, 5-7 short gastric branches and left gastroepiploic artery. VENOUS SUPPLY: Splenic vein joins with the Superior mesenteric vein to form portal vein.

13. LYMPHATIC DRAINAGE: Spleen has no proper lymphatics. It drain into pancreaticosplenic artery. NERVE SUPPLY: Sympathetic fibres derived from coeliac plexus. APPLIED ANATOMY: Splenomegaly-It is seen in malaria,leukemia and cirrhosis of liver. Splenectomy-removal of spleen due to injury. Splenic puncture is done to measure portal venous pressure. Splenic infarction – obstruction in the splenic arteries causes reffered pain in the left shoulder.
