Which arteries supply the adrenal glands?

The adrenal glands receive blood supply from multiple arteries, making the correct choice a comprehensive one.

The middle adrenal arteries, which originate directly from the abdominal aorta, specifically supply the adrenal glands, ensuring a direct and robust blood supply. In addition to these arteries, the inferior phrenic arteries also contribute to the blood supply of the adrenal glands, particularly providing branches that help support the superior aspects of the glands. Furthermore, although the renal arteries predominantly supply the kidneys, they can also give rise to small branches that may indirectly assist in vascularizing the adrenal glands, especially concerning their lower portions.

This multi-faceted arterial supply underlines the significance of having multiple sources feeding the adrenal glands, which is critical for their function in hormone production and regulation. Understanding these connections is vital for clinical considerations, especially in conditions that may affect adrenal function or during surgical interventions related to these glands.
