questions with correct answers rated
100% correct.
Ovaries ANS - Female gametes are produced here.
Oviduct ANS - The site of fertilisation.
Endometrium ANS - The lining of the uterus.
Corpus Luteum ANS - After ovulation the Graafian Follicle changes function and develops in this.
Seminiferous Tubules ANS - Male gametes develop here.
Testosterone ANS - Hormone produced in the interstitial cells between the seminiferous tubules.
Prostate Gland ANS - Gland that secretes nutrients and neutralizing fluids into the semen.
Seminal Vesicles ANS - Two small glands that secrete a fluid rich in sugar that nourishes and helps
sperm move.
Seminal Fluid ANS - Substance in which sperm are suspended that is produced by three glands in the
abdominal cavity.
Pituitary Gland ANS - Produces two sex hormones. LH and FSH.
Luteinising Hormone ANS - Ovulation in females, formation of corpus luteum.
, Follicle Stimulating Hormone ANS - WOMEN: initiates growth of ovarian follicles each month and
stimulates ovulation; MEN: stimulates sperm production.
Interstitial Cell Hormone ANS - Initiates secretion of testosterone in males.
Oestrogen ANS - Stimulates growth of uterus lining, inhibits FSH production, stimulate development of
duct system, inhibits prolactin, increases uterine sensitivity to oxytocin, stimulates LH production.
Progesterone ANS - Hormone produced by the corpus luteum in the ovary and the placenta of
pregnant women. Inhibits FSH production and retains endometrium.
In Vitro Fertilisation ANS - IVF
IVF ANS - Sperm and ova are mixed in a 'test tube' outside the female's body and then one of the
developing embryos is implanted in the uterus.
Contraceptive Pill ANS - Prevents ovulation by faking pregnancy with a mixture of progesterone and
oestrogen which inhibit FSH production.
Zygote ANS - The first cell produced from the fertilisation of an ovum by a sperm in the oviduct.
Cleavage ANS - When the zygote divides repeatedly to produce a ball of cells.
Dizygotic Twins ANS - Non identical. Result from two ova being fertilised by different sperm.
Monozygotic Twins ANS - Identical. Result from the group of cells from one fertilised ovum splitting in
two during cleavage.
Implantation ANS - When the ball of cells reaches the uterus and embeds itself into the endometrium.
