Adrenal Gland, Cortex - Atrophy - Gallery

Adrenal gland, Cortex - Atrophy in a female Sprague-Dawley rat from a chronic study. The width of the cortex (C) and the overall size of the gland are decreased; the capsule (arrow) is thickened by fibrosis. M = medulla.

Adrenal gland, Cortex - Atrophy in a female Sprague-Dawley rat from a chronic study (higher magnification of Figure 1). The width of the zona fasciculata is decreased, and the cell nuclei in the outer zona fasciculata are crowded, suggesting a decrease in size. C = cortex, M = medulla.
