A
Testes
- arterial supply: testicular artery (arise from abdominal aorta)
- venous drainage: pampiniform venous plexus which converge to form testicular veins that eventually drain into IVC/renal vein
- lymphatic drainage: Lumbar lymph nodes
- innervation: Parasympathetic - vagus nerve; Sympathetic - T10 to T11 segments
