Question 5

Where do the inferior adrenal arteries stem from?

Answer 5

the Left and right renal arteries

Question 6

What is the microvasculature of the adrenal gland?

Arteries and venous drainage

Answer 6

Cortical arteries irrigate cells of the cortex and join the medullary arterioles

capillaries in both cortex and medulla join to from the medullary veins that drain into the adrenal veins
