Terms | Definitions |
|---|---|
 Ovary | Paired. Female Gonads, contain germ-line cells that undergo meiosis to produce eggs; also contain follicle cells that secrete estrogen & progesterone (female) |
| Fallopian Tube | 2 ciliated tubes that draw the egg into the tubes and propel it toward the uterus. Fertilization (sperm joins egg) usually occurs in this. (female) |
| Fallopian Tube | Fertilization (sperm joins egg) usually occurs in this (female) |
| Uterus | Muscular womb; the lining is called the endometrium (female) |
| endometrium | Lining of the Uterus (female) |
| Cervix | Muscular entrance to the uterus. (female) |
| Pepsmeare | Cells from the cervix are collected & cultured to check for cervical cancer in this test |
| HPV (Human Papilloma Virus) | virus that causes cervical cancer |
| True | True or False, there IS a vaccine for HPV (Human Papilloma Virus) |
| Vagina | Birth canal; where the Penis deposits the sperm (female) |
| Urethra | tube that releases urine (female) |
| Urinary Bladder | Sac that stores urine (female) |
| Scrotum | An external sac to house the testes; keeps testes ~2 celsiuc cooler than body temperature (male) |
| Testis | Male gonads; contain germ-lined cells inside highly coiledd seminiferous tubules; between these tubes are other cells that make testosterone (male) (singular) |
| Epididymis | a set of tubes in which sperm are stored until releases or broken down; tey also develop flagellum here. (male) |
| Vas Deferens (Vasa Deferentia) | tubes that propel sperm/semen to the urethra (male) |
| Vasectomy | vasa deferentia are cut and tied off, sometimes burned, result: semen has no sperm cells inside. (male) |
| Seminal vesicle | paired. glands that releaseseminal fluid and rich in fructose (male) |
| prostate | releases a basic (> 7 pH) fluid into the semen; this neutralizes the acidity of the female reproduction tract (male) |
| Cowper's Gland | releases small amount of seminal fluid (male) |
| Cowper's Gland | other name for the Bulbourethral Gland (male) |
| Urethra | muscular tube; passage way for semen and urine (male |
| Penis | Male copulatory organ (male) |
| Bladder | Storing Urine |
| oocytes; 400; eggs | the female is born with two million ______ halted at Prophase I. Only ___ of which will mature into ____ with in her lifetime |
| 14; follicle | on which day of the menstrual cycle is the ovum released from the ____ at ovulation |
| ovary | the follicle is on the surface of the __ |
| 14 | around what day does ovulation occur? |
| cilia | what move the ovum into the fallopian tube? |
| Vagina | where is sperm deposited? |
| the mouth of the uterus | where does the vagina lead to? |
| Cervix | The muscular sphincter at the opening of the uterus |
| 24 hours | with is the lifespan of an unfertilized ovum ? (how long before it dies?) |
| 28 | "disintegration of the endometrium (vaginal lining)" occurs on what day? |
| peristaltic contractions | how does the ovum or zygote move to the uterus? |
| X | What chromosome(s) are ALL egg cells? (ABC order) |
| X or Y | What chromosome(s) are ALL sperm cells? (ABC order) |
| XX; female | If an X chromosome fertilized an egg, the sex chromosome pattern is? What gender is it? |
| XY; male | If a sperm with a Y Chromosome fertilizes the egg, what will the chromosomal pattern be? what is the gender? |
| false | True or False: there can be a YY chromosomal pattern. If true, what is the gender? |
| Seminiferous Tubules of the Testes | Where does Meiosis in males occur? |
| Sperm | what does meiosis in males produce? |
| eggs | what does meiosis in females produce? it occurs while the fetus is still in the womb. |
| 23 | how many chromosomes does one sperm cell have? |
| 3 | how many parts does a human sperm cell have? |
| head; middle region; flagellum | name the parts of a human sperm cell. from anterior to posterior (top to bottom) |
| the tail | what is the "flagellum" of a human sperm cell commonly called? |
| Nucleus; DNA | What does the sperm cell head contain? what is inside it? |
| acrosome | located at the tip of the head of a sperm cell. enables the sperm to break down the cells and protein layer protecting the egg |
| mitochondria | what is in the middle region of a sperm cell? |
| mitochondria | what produces energy (ATP) to the flagellum in a sperm cell? |
| flagellum | the tail. long and slender. moves the sperm. |
| scrotum | where are the testes stored? |
| testes | what does the scrotum house? |
| epididymis | storage and maturation area for the sperm (located directly on the testis) |
| Prostate | secretes a fluid that has a stimulating effect on sperm |
| vas deferens | during intercourse (copulation)where does sperm travel to/through? (singular) |
| vasa deferentia | plural of vas deferens |
| vasa deferentia | where do the reproductive and urinary tracts join in a male? (plural) |
| urethra | in a male, where is sperm emptied through? |
| urethra | in a male, where is urine emptied through? |
| 2-3 months | what is the maturation period for sperm |
| continuously | how often does an adult male produce sperm? |
| broken down and molecules are reused | what happens to sperm that is not ejaculated from the body? |
| several hundred million | how many sperm does a male produce each day of his life? |
