Figure 26‐3. A bovine ovary (intact above, cut
section below) demonstrating a corpus luteum and ×12.5
follicles. The tunica albuginea (f) of the bovine
ovary is thin, which allows the “crown” (a) of the (C)
corpus luteum (c) to bulge along the surface and be
palpable per rectum. One large follicle is grossly
visible (b), but has collapsed (d) in the cut section. A
small follicle is also visible on cut section (e). Source:
