Superior suprarenal artery

Superior suprarenal artery

The superior suprarenal artery is one of the three arteries that supply the adrenal glands. It is shown here in red.

The Superior suprarenal artery is one of the three arteries that supply the adrenal glands. It originates from the inferior phrenic artery and travels to the adrenal gland, where it branches into several smaller arteries.

Structure

The superior suprarenal artery is a small branch of the inferior phrenic artery. It travels along the superior aspect of the adrenal gland, giving off several smaller branches that penetrate the gland and supply it with blood.

Function

The superior suprarenal artery, along with the middle suprarenal artery and the inferior suprarenal artery, provides the adrenal glands with the necessary blood supply for their function. The adrenal glands produce several important hormones, including cortisol, aldosterone, and adrenaline.

Clinical significance

Damage to the superior suprarenal artery can lead to insufficient blood supply to the adrenal glands, potentially resulting in adrenal insufficiency. This can cause a variety of symptoms, including fatigue, low blood pressure, and hyperpigmentation.
