Anatomy (Internal Organs+Glands) · MU Sofia

100. Suprarenal glands. Paraganglia.

Covers the position, size and blood, venous, lymphatic and nerve supply of the suprarenal glands, with their relations to neighbouring structures listed one by one. It then describes the cortex's three zones and the medulla's chromaffin cells, and moves on to paraganglia, their carotid and aortic bodies, and their role in monitoring blood pressure and gases.

SUPRARENAL GLAND

  • Also known as Adrenal gland.
  • Paired Retroperitoneal organ.
  • Located on the upper poles of the kidneys at the level of TII-TI2.
  • The right adrenal gland is triangular in shape, and the left is semilunar.
  • The right is situated more caudally than the left one.
  • Weight ~ 4.2 - 5 g.

Vasculation:

Arterial blood supply:

  • 1 Superior adrenal/suprarenal artery – from the inferior phrenic artery
  • 2 Middle adrenal/suprarenal artery – from the abdominal aorta
  • 3 Inferior adrenal/suprarenal artery – from the renal artery

Venous drainage: – suprarenal veins (on the right side into the inferior vena cava, on the left into the left renal vein)

Lymphatic drainage: lumbar nodes and posterior mediastinal nodes

Sympathetic and parasympathetic part of the autonomic nervous system, sensory: – adrenal/suprarenal plexus

Syntopy:

  • 1 Cranially: diaphragm, subhepatic space
  • 2 Caudally: upper pole of the kidney
  • 3 Ventrally on the right side: liver
  • 4 Ventrally on the left side: stomach
  • 5 Ventrally on both sides: prerenal layer of the renal fascia, perirenal fat capsule
  • 6 Dorsally: perirenal fat capsule, retrorenal layer of the renal fascia, pararenal fat body, diaphragm, costodiaphragmatic recess
  • 7 Medially on the right side: inferior vena cava
  • 8 Medially on the left side: abdominal aorta
  • 9 Laterally: pararenal fat body
