The suprarenal plexus is formed by branches from the celiac plexus, from the celiac ganglion, and from the phrenic and greater splanchnic nerves, a ganglion being formed at the point of junction with the latter nerve.
Because the ANS, specifically the sympathetic division, exerts direct control over the chromaffin cells, the hormone release can occur rather quickly. [2] In response to stressors, such as exercise or imminent danger, medullary cells release the catecholamines adrenaline and noradrenaline into the blood. Adrenaline composes about 85% of the ...
[1] [2] T5–T9 [1] T5–T9 T5–T10 [3] The greater splanchnic nerve travels through the diaphragm and enters the abdominal cavity. Its fibers synapse at the celiac ganglia. [4] The nerve contributes to the celiac plexus, a network of nerves located in the vicinity of where the celiac trunk branches from the abdominal aorta.
The renal plexus is a complex network of nerves formed by filaments from the celiac ganglia and plexus, aorticorenal ganglia, lower thoracic splanchnic nerves and first lumbar splanchnic nerve and aortic plexus. [1] The nerves from these sources, fifteen or twenty in number, have a few ganglia developed upon them.
Note 1: The renal artery also provides a branch to the inferior suprarenal artery to supply the adrenal gland.; Note 2: Also called the cortical radiate arteries. The interlobular artery also supplies to the stellate veins.
The suprarenal veins are two in number: . the right ends in the inferior vena cava.; the left ends in the left renal or left inferior phrenic vein.; They receive blood from the adrenal glands and will sometimes form anastomoses with the inferior phrenic veins.
The superior suprarenal artery is an artery in the abdomen. It is a branch of the inferior phrenic artery, itself a branch of the aorta. It supplies the adrenal gland.
