OOgenesis

Spermatogenesis

Testes Slide

Things to Identify:
Tunica Albuginea
Seminiferous tubules
Sustentacular (Sertoli) Cells- supporting cells of the sperm
Type A Spermatagonia- located near basal laminae, undergo mitotic division (2n)
Type B Spermatagonia- go through meiosis (2n), light cytoplasm with distinct nucleus
Primary Spermatocytes- (2n) located closer to the lumen, cell structure not as organized as a Type A
Spermatazoa- (n) pointed nucleus located in the lumen, seed shaped
Interstitial Cells of Leydig- located outside of the seminiferous tubules, produce androgens (testosterone)

Vagina Slide

Things to Identify:
Mucosa- nonkeratinized stratified squamous epithelium
Smooth Muscle
Adventitia

Uterine Tube

Things to Identify:
Mucosa Layer- contains ciliated and nonciliated simple columnar cells

Penis Slide

Things to Identify:
Skin- keratinized stratified squamous epithelium
Tunica Albuginea
Corpora Cavernosa- superior to the urethra
Corpus Spongiosum- surrounds the urethra
Urethra- reindeer shaped area, epithelium in spongy (penile) urethra is stratified columnar

Prostate Slide

Spermatic Cord

The spermatic cord is a bundle of nerve fibers that is enclosed with nerve fibers and lymphatics in a connective tissue sheath. Contains the ductus deferens.

Things to Identify:
Ductus Deferens- contains sperm, has a wavy looking epithelium, pseudostratified epithelium
Blood Vessels
Arteries
Veins

Epididymis Slide

Things to Identify:
Epithelial Tissue: Pseudostratified columnar epithelium containing microvilli called stereocilia

Sperm Slide

Things to identify:
Sperm
Head- contains acrosome, a hydrolytic enzyme that enables the sperm to penetrate an egg
Midpiece
Flagellum- tail, makes sperm motile
