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.

Suppose the (1) ____ oocyte is on its way down an oviduct when a female and male are engaged in sexual intercourse, or (2) _____. The male sex act requires (3) _____________ and ejaculation. During coitus, pelvic thrusts stimulate the penis, the female’s (4) ____________, and the vaginal wall. The mechanical stimulation induces involuntary contractions in the male reproductive tract. It forces sperm from the (5) _____ and contents of seminal vesicles and the (6) ________ gland into the urethra. The substances mix and form (7) _____, which is ejaculated into the vagina. During male (8) ________, the end of the sex act, strong sensations of physical release, warmth, and relaxation dominate. Similar sensations typify female orgasm. Following sexual intercourse, (9) _____ are in the vagina. Fertilization most often takes place in the upper portion of the (10) _____. When living sperm contact an oocyte, they release (11) ______ that clear a path through the zona pellucida. Usually only one sperm fuses with the secondary oocyte; only its nucleus and centrioles do not degenerate in the oocyte’s cytoplasm. Sperm penetration induces the secondary oocyte and the first polar body to finish meiosis (12) _______. There are now three polar bodies and a mature egg, or (13) ______. As the sperm and egg nuclei fuse, their chromosomes restore the (14) ____ number for a brand new zygote. A. Orgasm H. Epididymis B. II I. Semen C. Clitoris J. Sperm D. Enzymes K. Erection E.
