Splenic Nerve, Anterior View

Description

Oriented in anterior anatomical position, the spleen appears as an elongated, convex organ with its diaphragmatic surface facing forward and its visceral surface turned posteriorly toward the stomach, left kidney, and tail of the pancreas. Along the medial border, fine splenic nerve fibers converge toward the splenic hilum, then distribute beneath the splenic capsule as a branching plexus. Their course logically parallels the splenic artery and vein within the splenorenal (lienorenal) ligament, with fibers entering and exiting near the hilum rather than across the smooth diaphragmatic surface. Color contrast emphasizes the neural arborization against the dark purple splenic parenchyma. Anterior emphasis on the splenic nerve bundle matters because splenic innervation is the main autonomic conduit to the spleen and a common teaching point for neuroimmune modulation and visceral pain pathways. Surgeons working at the splenic hilum, during splenectomy or distal pancreatectomy, routinely mobilize the splenorenal ligament and ligate the splenic vessels, a step where adjacent autonomic fibers and periarterial plexuses can be stripped or cauterized. This view also supports discussion of iatrogenic denervation when performing hilar dissection and how that differs from injury to the short gastric vessels near the gastrosplenic ligament. Use this illustration in abdominal anatomy and neuroanatomy teaching to connect sympathetic and parasympathetic pathways to a specific organ target, and in operative atlases describing hilar control, vascular pedicle isolation, and splenic capsule handling. It also fits immunology or physiology texts that need a clean, organ-level visualization of splenic autonomic nerves approaching the hilum and radiating under the capsule.
