Table 1. Neurovascular supply and lymphatic drainage of the spleen.

Characteristics	Structures involved
Arterial supply	Splenic artery, which further divides into five branches that do not anastomose, giving rise to vascular segmentation of the spleen
Venous drainage	Splenic vein, which later joins superior mesenteric vein to give rise to the portal vein
Innervation	Celiac plexus (sympathetic and parasympathetic)
Lymphatic drainage	Celiac lymph node (receives lymph from pancreaticosplenic lymph nodes)
