Suprarenal Gland

Suprarenal Gland


SUPRARENAL (ADRENAL) GLAND
  • Suprarenal (adrenal) glands are a pair of endocrine glands.
  • Situatedretroperitoneally in posterior abdominal wall on each side of vertebral column on upper pole of coressponding kidney.
  • Each gland measures 50 mm in height, 30 mm in breadth & 10 mm in thickness.
  • Weight- 5 gm.
  • Each suprarenal gland is divided into outer cortex &inner medulla.  

  

 

RIGHT SUPRARENAL GLAND

LEFT SUPRARENAL GLAND

Shape

  •   Pyramidal
  • Semilunar

Parts & relations

  •   Apex: Bare area of liver
  •   Base: Upper pole of right kidney
  • Upper end: Close to spleen
  • Lower end: Presents hilum, left vein emerges from here

Anterior surface

  •  Inferior vena cava
  •  Bare area of liver
  • Cardiac end of stomach,pancreas with splenic artery

Posterior surface

  • Right crus of diaphragm, right kidney
  • Left crus of diaphragm, left kidney

Anterior border

  • Presents hilum, right vein emerges

 

Medial border

  • Coelic ganglion, right inferior phrenic artery
  • Coelic ganglion, left inferior phrenic artery, left gastric arteries

Lateral border

  • Liver
  • Stomach

 ARTERIAL SUPPLY: through suprarenal vein

  1. Superior suprarenal artery (branch of inferior phrenic artery)
  2. Middle suprarenal artery (branch of abdominal aorta)
  3. Inferior suprarenal artery (branch of renal artery)
VENOUS DRAINAGE:
  1. Right suprarenal (adrenal) vein drains into IVC
  2. Left suprarenal vein drains into the left renal vein & then into IVC.
LYMPHATIC DRAINAGE:
  • From suprarenal glands drain into lateral aortic (para-aortic) nodes.
