hello friends welcome to the bible wars of anatomy today we discuss a spleen so we start with the introduction of spleen the spleen is a lymphatic organ which is connected to the blood circulatory system a small function is is a filtration of a blood it filters and removes the old and phrasal rbc from the circulation now we first see the location of this plane where it is located in the abdomen to locate the each and every organ in the abdomen we divide the abdominal cavity in the ninth quadrant right out of this nine quadrant the spleen is located in the manly in the left hypochondria or a left hypochondriac region and partly it is extended into the epigestric region that is the location in the body now we discuss its position how it is positioned in the body the split is directed downward forward and literally and it is reaching to the mid auxiliary light now it is directed or placed obliquely with the long axis of a 10th ray right so this is a position of the split now in this position it is a waged or a compress between the two structure that is the fundus of the stomach anteriorly and the diaphragm posteriority now we see its dimension uh to remember its dimension and weight you can remember the odd number 1 3 5 7 and 9 to 11. so first the one one inch for its thickness it is one inch thicker second is a three it is three inch broader third is a five it is five inch in the length right the next seven number seven is for a weight it is 7 ounce in the weight and 9 to 11 it is related to the 9th 10th and 11th ring so it is its dimension now we discuss the main part of the spleen that is the important for the viper point of view and also to remember the to keep the spleen in the proper anatomical position that is its external features so now the external feature remember it is having the first it is having it two hands anterior posterior it is having a three border the superior border the inferior border and intermediate border third thing it is having a two surface visceral surface diaphragmatic surface it is having fourth thing two angles enterobasal angle posterior basal angle and the last it is having one hiram we discuss one by one the first thing it is having the two ends these are nda and and the posterior the anterior and is more like a border rather than that see it is like a border it is a expanded and the anterior hand is directed downward forward and literally so it is also known as a lateral end and it is reaching up to mid axillary line so this is the border like and is anterior end right opposite to it is a posterior end see this is the rounded part that is the posterior and which is directed opposite to the indian upward backward and the medially upward backward and medially that is a posterior and this is the first thing second thing borders it is having a three bottle first the superior water lies superiorly it is a sharp superior border is having a characteristic nodes sometimes one sometimes two this nodes is present on the superior border but it is not constant second is the inferior border this is the superior water now the inferior water inferior water is around it see this is the inferior water okay this is the inferior border it is around it third is an intermediate border intermediate border lies on the right side or you can say on the inner side of the spline between the superior and the inferior border so this is intermediate border see this rounded is an intermediate ball superior water once again having a notch near the entire end inferior border which is around it intermediate border it is also rounded now the third thing it is having a two surface one is a diaphragmatic surface that is smooth and convex and the second is a visceral surface that is concave and the irregular this concave and the irregular is a visceral surface now the fourth thing it is having a true angle anterobasil angle posterior basal angle enterobasal angle is an angle between the superior border and anterior end we have seen the anterior end is like a border so between these two is a enterobasal angle this angle is the first most part of the spleen ah when the screen is pulpable when the spleen is enlarged so this is also known as a clinical angle of this plane second angle is a posterior basal see this this one the posterior basal angle around it is between the inferior border and the anterior and is a postero basal angle right so this is the angles the last part is highland you can see here some structures vessels this is the high lump and the splenic vessels and the nose is passed through this highland so this is the high lump of a split so these are the external feature of the screen you have to remember this feature to keep the spleen in the anatomical position but before that we see its relation see the abdominal organ is related to the peritoneum as well as other visceras so it is having a peritoneal relations and a visceral relation first we see the peritoneal relation of the spray peritoneum produce some folds which is directly attached to this plane we can we can call them as a ligament so such a first fold of the peritoneum is a gastros planic ligament gastrosplenic ligament that is extended or attached to the hilum of the spleen to the greater curvature of the stomach okay gastrosplenic ligament now you have to remember the content of the gastrosphere nucleic acid it contained the short gastric vessels short gastric visuals and associated lymphatic and sympathetic nerve this is the important fiber question as well as short question the second ligament is a linorenal ligament linorena lean means the latent word of the spleen renal means kidney linorenal ligament extend again from the hilar of the spleen to the anterior surface of the left kidney the important content of this ligament are the tail of pancreas over here the splenic vessels the pancreaticos planic group of lymph node and associated lymphatic and the sympathetic no the second requirement lino renal ligament thirdly government is not actual the ligament of the spleen it is not attached to the spleen only it support the anterior end of the screen like this that is phrenic phrenicopolic phrenico means diaphragm and colic large quantum so it is extend from the diaphragm above to the splenic fracture of the colon below this is the only training so these three ligament shows the peritoneal relation of the stream now comes to the visceral relation the visceral surface see this is the inner surface visceral surface is related to the certain visra and this visra make an impression the first such impression is a gastric impression the gastric impression is for the fundus of the stomach that is between the superior border and the intermediate border remember this is the most important impression to determine the uh to keep the spleen in the anatomical position it is the largest and the most concave impression of this plane the gastric impression for the fundus of the stem the second impression is the renal operation that is also concave that is present between the intermediate border and the inferior border this is a renal impression for the anterior surface of a left kidney third is a triangular impression near the interior and here this is the indian triangular amplitude that is a cooling impression for the splenic fracture of a colon for the splenic fracture of the colon the last is a pancreatic implication that is between the colic impression and the high pancreatic impression for the tail of the pancreas last this is the high lump which provides the attachment of gastrosplenic ligament and lino renal ligament so this is the visceral relation loss is the diaphragmatic relation see the diaphragmatic surface is a large and the convex that is related to the left dome of that now we discuss the anatomical position of a strain this plane first you have to keep the spleen in the left hand because plane lies in the left hypochondria second you have to keep this plane obliquely directed downward forward and literally in such a way that it makes an angle of 45 degree with the horizontal okay keeping the gastric impression the large and concave impression that is the gastric impression we have seen in the visceral surface the gastric impression superiorly okay superior the gastric impression superior so when you keep the gastric impression superiorly automatically the anterior hand faces anteriorly posterior and faces posted so this is the anatomical position of the spleen now discuss its blood supply spleen is supplied by the splenic artery which is a largest branch of a celectrum now it passes from the celiac trunk behind the pancreas to the hilam of the spray and it it scores it is the torture city provides the movement of a spleen during the respiration venustrine is it is drained by the splenic vein which passes behind the pancreas unite behind the neck of the pancreas will display a superior mesenteric vein and this will form the portal now last its applied anatomy first the palpation of the sprain see the normally you cannot palpate the spleen until it enlarges to its double size and it is palpated below the left postal margin second thing enlargement of the spleen is known as a splenomegaly you can see the splenomegaly in certain diseases like malaria leukemias etc third thing in certain diseases we have to remove the spleen which is known as a splenic tommy now what cat should be taken during the spleen economy the cat should be taken to not to injure the tail of the pancreas because the steel of the pancreas is in reach with the eyelid of a langerhans and also you have to keep the two particles gastrosplanic and the linorenal ligaments be safe because it contain the vessels okay splenectomy next fourth splenic puncture splenic puncture is turned with the lumbar puncture needle it to be done to diagnose certain diseases for splenic puncture the lumbar puncture needle is introduced through the left mid axillary line in the space between the ninth and the tenth ring splenic puncture now the splenic infant we have seen the blood supply it is supplied by the splenic artery splenic artery divides in the spleen form the particles and the smallest branch of this planet are razor and artery it will not anastomos with its neighboring branch so when this plane artery the branch of the smallest branch of this planic artery is a block that part of this plane undergo necrosis that is known as a splenic infa and the splenic infarct will produce the pain which is referred to the left shoulder region this is known as a cavers sign right spleen is also a common organ to be ruptured during the road traffic accident when there is an injury to the left upper abdominal area splenic rupture so this is about this plane thank you if you like our video click on the like button and share with your friends to get the regular updates on anatomy video
