This set of Human Anatomy Questions and Answers for Entrance exams focuses on “Female Genital Organs – Ovaries & Uterine Tube”.
1. The outside layer of the oocyte is the ______________
a) Zona pellucida
b) Theca interna
c) Theca externa
d) Antrum
View Answer
Explanation: Zona pellucid is the glycoprotein layer surrounding plasma membrane of mammalian oocyte. It is a vital part of the oocyte.
2. The mature follicle is also called as _____________
a) Secondary follicle
b) Graafian follicle
c) Granulosa cell
d) Primary follicle
View Answer
Explanation: Graafian follicle is present inside an ovary and is a minute cyst within an egg or ovum.
3. Name the primary sex organ of a female.
a) Testis
b) Mammary glands
c) Ovaries
d) Fallopian tube
View Answer
Explanation: Ovaries are the part of the female reproductive tract. They produce eggs as well as hormones.
4. Antrum is the cavity of _________
a) Gastrula
b) Blastula
c) Graafian follicle
d) Ovary
View Answer
Explanation: Antrum is the cavity present in graafian follicle. It is filledwith follicular fluid.
5. Capacitation of sperm occurs in ___________
a) Female genital tract
b) Vas deferentia
c) Vagina
d) Penis
View Answer
Explanation: Capacitation is the maturation of the spermatozoon. Glycoprotein coat and seminal proteins are removed from the surface of sperms acrosome. This takes place inside female reproductive tract.
6. The Mullerion duct in the female amniotes develops into __________
a) Uterus
b) Ureters
c) Oviduct
d) Vagina
View Answer
Explanation: Mullerion duct are primordial anlage of female reproductive tract. They differentiate to form fallopian tube, uterus, cervix and vagina.
7. Polyspermy is prevented by ____________
a) Fertilization cone
b) Fertilization membrane
c) Jelly coat
d) Tertiary membrane
View Answer
Explanation: Polyspermy is the condition in which an egg is fertilized by more than one sperm. This is not seen in humans. After the fusion of one sperm into the egg, the fertilization membrane is formed to prevent the entry of other sperms thus preventing polyspermy.
8. Fertilization of egg by sperm occurs in ____________
a) Oviduct
b) Ovary
c) Uterus
d) Vagina
View Answer
Explanation: Oviduct is also known as fallopian tube or uterine tube. The fertilization of the egg by sperm occurs in fallopian tube.
9. If mammalian ovum fails to get fertilized which one of the following is unlikely?
a) Corpus luteum will degenerate
b) Estrogen secretion decreases
c) Primary follicle starts developing
d) Progesterone level declines
View Answer
Explanation: Progesterone is a naturally occurring steroid hormone. It is released by ovaries. It is necessary for implantation of fertilized egg. If fertilization fails to take place the Progesterone levels declines.
10. Fallopian tube is differentiated into ____________ parts.
a) 3
b) 4
c) 2
d) 5
View Answer
Explanation: Fallopian tube is differentiated into 3 parts. They are ampulla, isthmus and uterine part.
