ADRENAL GLAND

1
ADRENAL GLAND

• Location
• - anteromedial to the kidney
• - within the perirenal fat (adipose capsule)
• - right adrenal ? pyramida, horizontal
• - left adrenal ? semilunar and generally
• more vertical

2

• Structure
• Hilus anterior surface
• adrenal vein emanates.
• The adrenal parenchyma is divided into 2 zones
• 1. Cortex Adrenal ? mesoderm
• 2. Medulla Adrenal ? embryonic neural
• crest
  tissue

3

• Vaskulature
• Adrenal arteries arise from 3 sources
• 1. Superior suprarenal arteries ? inferior
• 
  phrenic artery
• 2. Middle suprarenal arteries ? the aorta
• 
  abdominal
• 3. Inferior suprarenal arteries ? renal
• 
  artery

4

• Vein
• Right adrenal vein usually drains medially into
  the inferior vena cava
• Left adrenal vein usually drains inferiorly into
  the left renal vein.
