Video narration
Which part of this adrenal gland contains the three zones? Think of it as an onion: the outer cortex is arranged in zones, while the center is the inner medulla-not one of those cortex zones. Starting at the outside of the cortex, you see zona glomerulosa, the first zone. Beneath it is zona fasciculata, the middle zone. Closest to the medulla is zona reticularis, the innermost zone. Read them together, outside inward. Now, about "shonak." The request places it in the zona glomerulosa, but the supplied information does not identify it as a recognized adrenal structure. So it should not be presented as confirmed anatomy, even as a tiny label. Mark it unverified, or leave it out until a reliable source defines it. So, which three zones belong on the diagram? Zona glomerulosa, zona fasciculata, and zona reticularis. "Shonak" needs verification before it gets a label.
