What structure will you see around secondary follicles (red circles) that will look like a pink circle?

"egg shell" or zona pellucida

Yellow circle? squamous follicular cells White? cuboidal follicular cells in a ring Red? follicular cells specialize, called the theca. Cells of theca? What are they secreting?

Yellow circle: primordial follicles White: primary follicles Red: secondary follicles Cells called **granulosa cells,** later will secrete estrogen

What is the green line tissue? What is between the yellow lines? Purple cells? (not outlined)

Green line: Germinal epithelium Yellow lines: stromal cells Stromal/Follicular cells (the ball structures are all the follicles)

What letter will the follicles be embedded at different sizes?
