MAMMALIAN REPRODUCTION<br />Mammary glands<br />“Mammary glands are present in both sexes but normally produce milk only in females. Though not part of the reproductive system, the female mammary glands are important to reproduction. Within the glands, small sacs of epithelial tissue secrete milk, which drains into a series of ducts opening at the nipple. The breasts contain connective and fatty (adipose) tissue in addition to the mammary glands. Because the low level of estradiol in males limits the development of the fat deposits, male breasts usually remain small.”<br />,[object Object]
Female
StructureFunctionfolliclesStructure in the ovary that contains oocyte, a partially developed egg. It also releases a primary female sex hormone, estrogen, specifically estradiolCorpus luteumA tissue in the ovary that forms from the collapsed follicle after ovulation. It secretes additional estradiol and progesterone which helps maintain the uterine lining during pregnancyOviduct/fallopian tubeA tube connecting the ovary to the uterus. Using wavelike motions, the eggs released from the ovary is brought to the uterusOvaryproduces female gametes and reproductive hormones.Uterusa.k.a the womb. It is where eggs are fertilized and developendometriumInner lining of the uterus that is rich in blood vessels. The rich supply of blood vessels allow an optimal situation for implantation of blastocystcervixNeck of the uterus; leads to the vagina; mucus forms plug to prevent infection; allows the flow of blood from uterus to vagina; directs the sperm into uterusvaginaMuscular but elastic chamber; site for insertion of penis and deposition of sperm during copulation; serves as birth canal and opens to the vulva, the external female genitalia Labia majoraThick, fatty ridges that protect the rest of the vulvaLabia minoraSlender skin folds that borders the vaginal opening and the separate opening of the urethraHymenThin piece of tissue that partly covers the vagina; ruptured during sexual intercourseclitorisLocated at the upper intersection of the labia minora; consists of a short shaft, glans/head and prepuce(fold of skin covering the glans); richly supplied with nerve endings, making it one of the most sensitive points of sexual stimulation; becomes erect during arousalBartholin’s glandsLocated slightly below and to the left and right of the vaginal opening; secretes mucus to lubricate the vagina
MaleStructureFunctionTestes (singular, testis)Male reproductive organ in which sperm and reproductive hormones are producedSeminiferous tubulesHighly coiled tubes in the testis that produce spermLeydig cellsScattered between seminiferous tubules; produce testosterone and androgenScrotum Houses the testes; maintains the temp required for spermatogenesis. (which is about 2 degrees Celsius lower than the temp in the abdominal cavity)epididymisCoiled tubule adjacent to the testes; storage area of spermVas deferensDuring ejaculation, the sperm is propelled through this muscular duct from the epididymis to the urethra.Ejaculatory ductTransports sperm from the vas deferens to the urethra; the convergence between the vas deferens and a duct from the seminal vesicleUrethra Outlet tube for both the excretory system and the reproductive system (urine and semen)Seminal vesicle“A gland in males that secretes a fluid component of semen that lubricates and nourishes sperm”; fructoseSemenFluid ejaculated by male during orgasm; contains sperm and secretions from the following glandsProstate gland“A gland in human males that secretes an acid-neutralizing component of semen”; for acidity of the vaginal tract; contains anticoagulant enzymes and citrate (a sperm nutrient)Bulbourethral glandEven before ejaculation, it secretes clear mucus that neutralizes any acidic urine in the urethra. Also contains sperm -> high failure rate for coitus interruptusPenis An external reproductive organ; contains the urethra and 3 cylinders of erectile tissue; its erection allows insertion into the vagina; baculum- bone in the penis which provides further stiffening (present in rodents, raccoons, walruses, whales, and several other mammals). glans penis-head of the penis and more sensitive to sexual stimulation.<br />,[object Object]
