Makroskopische Anatomie, Embryologie und Histologie des Index: 1–9 A B C D E F G H I J K L M N O P Q R S T U V W X Y Z Multi-polar sympathetic ganglion cells are found between chromeaffin cells. Depending on the production of adrenaline and norepinephrine, the chromeaffin cells are distinguished between the A (95%) and N cells (5%). The adrenal medulla contains chromeaffin cells (catecholamine production), which are arranged in strands with intervening blood sinus. The mineralocorticoids are produced from the zona glomerulosa, the glucocorticoids and androgens mostly from the zona fascicularis and reticularis.

The assignment of the adrenal hormone production to individual layers is not fully possible. Microscopic Anatomy (Histology) of the adrenal glands Adrenal CortexĪ thin capsule covers the adrenal cortex from outside to inside the cortex consists of three layers:

Nerve supply: from the suprarenal plexus, splanchnic nerves and vagus nerve.

suprarenalis joins: right in the vena cava and left renal vein.

Inferior adrenal artery: from the renal artery, often several branches.

Superior adrenal artery: from the inferior phrenic artery, often several branches.

Vascular and Nerve Supply to the Adrenal Glands The cut surface of the adrenal gland is divided into the outer yellow-gold adrenal cortex and brown-red inner adrenal medulla.Īnatomical neighborhood: cranial diaphragm, anterior liver (right) and pancreas (left), caudal the kidney and medial vena cava (right) and aorta (left).

The weight of the two adrenal glands is about 8 g. The adrenal glands are a paired endocrine organ located in the retroperitoneum above the upper poles of the kidneys.
