These surfaces are distinguished based on their anatomical position and the organs they relate to. The diaphragmatic surface is the convex outer surface of the spleen, which lies in contact with the inferior surface of the diaphragm. It is smooth and rounded, conforming to the shape of the diaphragm above it. This surface is directed upward, backward, and laterally, and is separated from the 9th to 11th ribs by the diaphragm and the costodiaphragmatic recess of the pleural cavity. Because of this close proximity, any enlargement of the spleen (splenomegaly) can cause discomfort in the lower thoracic region and may be confused with left-sided pleuritic or lower lung pathology. The visceral surface is concave, irregular, and directed anteromedially. It faces the abdominal cavity and is molded by the impressions of adjacent organs. This surface is important because it reveals the close anatomical relationships of the spleen. It is divided into several impressions: – The gastric impression lies anterior and superior, caused by the fundus and greater curvature of the stomach. – The renal impression is more posterior and inferior, where the spleen lies against the upper part of the anterior surface of the left kidney. – The colic impression lies anteroinferiorly, molded by the left colic (splenic) flexure of the transverse colon. – The pancreatic impression, found near the hilum, is formed by the tail of the pancreas, which lies within the splenorenal ligament and often enters the hilum. The hilum of the spleen, located along the visceral surface, is where the splenic artery, splenic vein, lymphatics, and autonomic nerves enter or exit the organ. This region does not have a peritoneal covering and serves as the attachment site for two important peritoneal ligaments: the gastrosplenic ligament, which connects the spleen to the greater curvature of the stomach and contains short gastric and left gastroepiploic vessels, and the splenorenal ligament, which connects the spleen to the left kidney and contains the splenic vessels and tail of the pancreas. Understanding the surfaces and their relations is clinically important in interpreting imaging studies and in planning surgical procedures such as splenectomy. Also, the visceral surface helps explain how disease processes such as infections, malignancies, or trauma can spread between adjacent organs. #SpleenSurfaces #GrossAnatomy #SpleenAnatomy #NEETPG2025 #FMGE2025 #USMLEprep #MBBSAnatomy #VisceralRelations #DiaphragmaticSurface #MedicalEducationIndia #DoctorsOfInstagram #AnatomySimplified #SurgicalAnatomy #SplenicHilum #AbdominalAnatomy #ClinicalAnatomy #YouTubeDoctors
