Document Summary

When ever the body is biochemicallly ready to begin producing and releasing sex cells. Gonads will produce the necessary hormones to allow reproduction. Make gamedes or sex cells ---> eggs or sperm. Other (accessory) structures that play a role in reproduction. Ducts: what send the gamedes and any nutrition required. Penis is needed to send sperm out. Hormones play a role in development of the fetus. Food, sleep, and sex: testes, found in the scrotum, what makes and beings sending sperm. Pathway of sperm: insert picture drawn during class, scrotum, delicate, skin with fascia and two muscles. Y chromosome determines this: made from the peritoneum- abdominal pelvic region. The tissue circulates and forms to begin the testes: develop through hormone assistance, then they descend to the scrotum- usually three days after birth, protection. Initially moves sperm: babies can"t swim, blood testis barrier, prevents immune system response to sperm antigens. Sertoli cells: barrier and sertoli cells protects sperm from wbcs.

You are correct that males produce sex hormones. For example, the testes produce testosterone which plays a role in spermatogenesis. As a way to expand the discussion, can you briefly discuss the hormones produced by female reproductive structures?

An ovum is released by a mature ovarian follicle, but the subsequent corpus luteum does not secrete progesterone. If the ovum is fertilized, is implantation possible? Is a full-term pregnancy possible? Explain.

The reproductive system may seem a bit isolated from other body systems in that its purpose is to create new life, not just maintain existing life. But there are significant relationships between the reproductive system and other body systems. Name three organ systems that the reproductive system especially depends upon, and briefly explain that dependence. Then name two systems whose anatomy or physiology is influenced by the hormones of the reproductive system, and describe these influences.

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.
