Document Summary

Overview of functional components: site of formation of sperm = testes, transport and storage of sperm is the epididymis, vas deferens, urethra, secretion support fluids (90% of semen) comes from accessory glands (seminal vesicle, prostate, and cowper"s gland) Introduction of sperm to vagina and penis: sperm cells and differentiation. Nurse cells (sertoli cells) inside the seminiferous tubule. Germ cells (including stem cells, sperm producing cells and mature sperm cells) Inguinal canal is a passage between the abdominal cavity and the scrotum. Testes form in the abdomen and at 7 months fetal life move through inguinal canal to scrotum. Spermatic cord is formed by migration of testes which drags along everything attached to it: vas deferens, blood vessels, nerves. Muscles of spermatic cord can retract testis for temperature regulation, 95 degrees f necessary for sperm formation. If testes don"t descend, no sperm but normal secondary sex characteristics. Tubules for storage and transport sperm: epididymis.

Overall, what is the function of the male accessory glands, andwhat are these?

		The bulbourethral glands, seminal vesicles and prostate producesemen which transports, nourishes, and protects sperm.
		The sertoli cells and the seminiferous tubules produce numerouscytokines that direct the development of sperm
		The testes produce cytokines that direct the development ofsperm and stimulates the production and release of testosterone bythe anterior pituitary
		The anterior and posterior pituitary release gonadotropins whichincrease the rate of spermatocyte maturation and stimulate theproduction of semen on a circadian cycle

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.
