Document Summary

Sperm is stored in epididymis (can be viable for 2 weeks) Semen is made of fluid from seminal vesicle and prostate. Mucosa formed of many irregular anastomotic folds lined with simple columnar epithelium. Formed of 30-50 tuboalveolar glands each with duct opening into prostatic urethra. Anastomosed channels lined with epithelium of low cuboidal cells sitting on ct. Simple columnar epithelium, variable in height giving it an irregular festooned appearance - site of fluid reabsorbtion. All lined by pseudostratified columnar epithelium, both secretory and absoptive. Surrounded by thick lamina propria and thick tunica muscularis of circularly and longitudinally arranged smooth muscle fibers. As you go up each layer, cells mature. Know these three! spermatagonia: stem cell spermatocytes: early-mid round/elongated spermatids. Phase involved with proliferation, renewal, and differentiation of. Lecture #22 - male reproductive tract: leptotene (l, zygotene (z, pachytene (ep, mid-pachytene (mp, late pachytene (lp) Spermatocytes undergo second meiotic division that yield haploid spermatids (reduction: spermiogenesis.

CHOOSE ALL THAT APPLY!!! Review your Lecture note packet on the Male Reproductive Anatomy. Read the following statements - and select all statements that are FALSE (hint: there are 4 FALSE answers in this question!)

		Testes - The 2 major functions of the testes are the produce spermatozoa and produce androgen hormones (testosterone)
		Testes - The nurse cells or sustentacular cells produce testosterone
		Epididymis - The epididymis has 3 regions - a head, body and a tail.
		Ductus (vas) Deferens - The extended portion of the ductus (vas) deferens as it nears the prostate gland is called the spermatic cord.
		Ejaculatory Duct - the ejaculatory duct passes through the prostate gland.
		Male Reproductive Glands - The prostate gland produces the majority of the volume of semen fluid.
		Male Reproductive Glands - The seminal vesicle produces fluids that help nourish the sperm, stimulates smooth muscle contraction and forms a temporary clost in the female's vagina.
		Male Reproductive Glands - The bulbourethral glands secrete a thick, alkaline mucus that helps neutralize any urinary acids that may harm the spermatozoa.
		Spermatozoa - The middle piece of the spermatozoa contains mitochondria and geneteic material in it.
		Spermatozoa - The head of the spermatozoa contains an acrosomal cap that contains enzymes that help during fertilization.
