	1. Testis, monkey, 400x, Slide 12 (H 9700) VE's 9th: pp. 285 & 287 Here is a labeled version of a seminiferous tubule . And another labeled testis with tunica albugenia. Here is a diagram of spermatogenesis. tunica albuginea (capsule) seminiferous tubules basement membrane spermatogonia primary spermatocytes (DNA=spermatogonia) secondary spermatocytes (DNA = 1/2 spermatogonia) spermatids (DNA = 1/4 spermatogonia spermatozoa (wedge shaped, near lumen) Sertoli cells (have plentiful cytoplasm and pale nuclei with prominent nucleoli) lumen interstitial tissue (between 3 seminiferous tubules)
	2. Penis, c.s. monkey, 40x, Slide 13, (H 9712) VE's 9th: p. 297 Upper image is a 10 view of entire penis. Here is a labeled view of the same image . The middle image shows the dorsal epidermis and corpora cavernosa. Here is a labeled version of the corpus cavernosum . The lower image is an enlarged view of the corpus spongiosus containing the cavernous urethra. Here are close up views of the stratified squamous epithelium and here is a labeled view of the skin with a nerve, 400x. cavernous urethra transitional epithelium (lines urethra) corpus spongiosum (surrounds urethra) tunica albuginea (2x) sinusoids corpus cavernosum artery or arterioles nerves
	FEMALE HISTOLOGY: 3. Ovary, monkey, 100x, Slide 14 (H 9800) VE's 9th: pp. 303 & 307 Here is a labeled view of an ovary with a developing follicle . tunica albuginea ovarian stroma (cortex) primordial follicles developing follicle: (Here is a labeled version of this same developing follicle.) corona radiata zona pellucida primary oocyte nucleus of oocyte
	4. Ovary: Graafian follicle 100x, Slide 15 (H 3785) VE's 9th: pp. 303 & 305 Here is a labeled Graafian follicle. Here is close up labeled version of the Graafian follicle . Graafian follicle theca externa theca interna (synthesizes androgen) basement membrane granulosa cells (converts androgen to estrogen, also called follicular cells) cumulus oophorus corona radiata zona pellucida oocyte antrum
	5. Corpus luteum (40x), Slide 16, (H 3815) VE's 9th: pp. 309 Here is the corpus luteum with labels capsule (was theca externa) glandular epithelium ovarian stroma (cortex)
	6. Fallopian tube, c.s. 100x, Slide 18, (H 9802) VE's 9th: p. 311 Here is a 100x view of the labyrinthine folds of the fallopian tube. Here is a labeled 400x view of the fallopian mucosa . circular smooth muscle fibers simple ciliated columnar epithelium labyrinthine folds of mucosa lamina propria peg cells (secretory, possess apical nuclei) ciliated cells (possess basal nuclei)
