This document provides a list of structures to label on pictures of a rabbit ovary cross section stained with hematoxylin-eosin. The structures include the ovarian epithelium, various stages of follicles from primordial to mature, oocytes at different developmental stages, follicular cells, interstitial cells, and blood vessels. The stain colors the nuclei blue-purple and cytoplasm and extracellular matrix pink to aid in identifying the structures microscopically.
