Q.No.	Que title	Option 1 (a)	Option 2 (b)	Option 3 (c)	Option 4 (d)
1	Ovulation in the human female normally takes place during the menstrual cycle	at the mind secretory phase	just before the end of the secretory phase	at the beginning of the proliferative phase	at the end of the proliferative phase
2	After ovulation Graafian follicle regreses into	corpus atresia	corpus callosum	corpus luteum	corpus albicans
3	Immediately after ovulation, the mammalian egg is covered by a membrane known as	chorion	zona pellucida	corona radiata	vitelline membrane.
4	Which one of the following events is correctly matched with the time period in a normal menstrual cycle ?	Release of egg : 5 th day	Endometrium regenerates : 5 – 10 days	Endometrium secretes nutrients for implantation: 11 – 18 days	Rise in progesterone level : 1 – 15 days
5	If mammalian ovum fails to get fertilised, which one of the following is unlikely ?	Corpus luteum will distintegrate.	Progesterone secretion rapidly declines.	Estrogen secretion increases.	Primary follicle starts developing
6	A human female reaches menopause aroung the age of__ yrs	50	15	70	25
7	A reaction of granules content which harden the zona pellucida and ensures sure block to polyspermy is	acrosomal reaction	cortical reaction	acrosin reaction	bindin reaction
8	Which part of the sperm plays an important role in penetrating the egg membrane ?	Allosome	Tail	Autosome	Acrosome
9	In oocyte secondary maturation occurs in	ovary	abdominal cavity	Fallopian tube	uterus.
10	Besides activating the egg another role of a sperm is to carry to egg	RNA	mitochondria	DNA	ribosomes
11	Preparation of sperm before penetration of ovum is	spermiation	cortical reaction	spermiogenesis	capacitation
12	The function of the secretion of prostate gland is to	inhibit sperm activity	attract sperms	stimulate sperm activity	none of these.
