Document Summary

Veins for grape like network so that heat is exchanged back to body and testes remain cool. Secondary sex organs: transmission of sperm, ducts epididymis, ductus, (vas) deferens, ejaculatory duct, urethra, accessory glands seminal vesicles, prostate gland, bulbourethral gland, copulatory organ penis. Inguinal hernias: coverings are related and we can guess the route it took. Testis: in the scrotum: from superficial to deep. Superficial fascia: dartos muscle: contracts the skin, when scrotum relaxed: loose skin, when contracted: very tight, cardboard like appearance. Right and left testes separated by a septum. Spermatic cord: has layers of connective tissue and muscle, contains the testis, found in the inguinal region, can open up the scrotum and pull out the spermatic cord, can find lots of layers. Cremasteric muscle: cremasteric muscle = elevate or descend the muscle when contracted or relaxed, removing this muscle, we can see the testis.

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. A) Scrotum B) Urethra C) Bladder C) Vas deferens D) penis E) Testis F) Epididymis G) Seminal vesicle H) Prostate gland I) Cowper's gland J) Glans penis
