Document Summary

Reproductive structures: primary sex organs, gonads (testes) Secrete sex hormones (androgens testosterone: secondary sex organs, needed for transmission of sperm, ducts. Ductus (vas) deferens (carry sperm from testes to ejaculatory duct) Urethra (runs through of the prostate gland: accessory glands. Bulbourethral gland: copulatory organ penis. Cold: draw testes towards body, skin wrinkles to increase thickness & reduce heat loss. Warm: muscles relax, so skin is flaccid & loose & testes hang low to increase skin: coverings are continuous with fascia of the spermatic cord, rich blood supply testicular artery, & venous drainage: nerves, vas deferens surface available for cooling (sweating, actions are performed by two muscles. Dartos muscle: layer of smooth muscle in superficial fascia, is responsible for wrinkling the scrotal skin. Gubernaculumbegins to shorten which pulls testis down and forward (in front of pubic bone) Drags parietal peritoneum along with it vaginal process: 8 months, 1 month old. Vaginal process continues to be pulled down into scrotal swelling.

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.

Identify the organ that corresponds with each of the following functions-1) Organ that allows the male to pass urine and semen leave the from his body; organ that enters the female's body during sexual intercourse.-2) Passage way through which urine and semen leave the penis.-3) Glands that produce sperm and the male sex hormone (testosterone)-4) Muscular sac where urine is stored.-5) Pouch of skin that holds the testes and controls temperature for sperm production.-6) The head or end of the penis: filled with highly sensitive nerve endings; particularly sensitive to stimulation.-7) Passageway for the sperm- 8) Coiled tube system in which sperm mature.
