Human Reproduction Quiz NEET
#1. The amnion of mammalian embryo is derived from
The extraembryonic or foetal membranes are amnion, chorion, allantois and Yolk sac. Amnion is formed from mesoderm on outer side and ectoderm on inner side. Chorion is formed from trophoectoderm and mesoderm whereas allantois and Yolk sac membrane have mesoderm on outerside and endoderm in inner side.
#2. The difference between spermiogenesis and spermiation is
Spermiogenesis is transformation of spermatids into spermatozoa whereas spermiation is the release of the sperms from sertoli cells into the lumen of seminiferous tubule.
#3. Hormones secreted by the placenta to maintain pregnancy are
Placenta releases human chorionic gonadotropic hormone (hCG) which stimulates the Corpus luteum during pregnancy to release estrogen and progesterone and also rescues corpus luteum from regression. Human placental lactogen (hPL) is involved in growth of body of mother and breast. Progesterone maintains pregnancy, keeps the uterus silent by increasing uterine threshold to contractile stimuli.
#4. GnRH, a hypothalamic hormone, needed in reproduction, acts on
Hypothalamus secretes GnRH which stimulates anterior pituitary gland for the secretion of gonadotropins (FSH and LH).
#5. Capacitation occurs in
Capacitation is increase in fertilising capacity of sperms which occurs in female reproductive tract.
#6. A temporary endocrine gland in the human body is
#7. Which of the following depicts the correct pathway of transport of sperms?
Pathway of transport of sperms in human male is Rete testis – Efferent ductules (Vasa efferentia) -Epididymis -Vas deferens.
#8. Several hormones like hCG, hPL, estrogen, progesterone are produced by
Hormones secreted by placenta are hCG, hPL, estrogen and progesterone.
#9. Fertilization in humans is practically feasible only if
- Fertilization in human is practically feasible only if the sperms and ovum are transported simultaneously at ampullary-isthmic junction.
#10. Identify the correct statement on inhibin
Inhibin is produced by granulosa cells in ovary and has direct effect on the secretion of FSH.
#11. Changes in GnRH pulse frequency in females is controlled by circulating levels of
High level is of estrogen and progesterone give negative feedback to hypothalamus for the release of GnRH.
#12. Select the incorrect statement :
In follicular phase of menstrual cycle, LH and FSH increase gradually.
#13. Ectopic pregnancies are referred to as
Any extra uterine pregnancy is ectopic pregnancy. Implantation can occur in the wall of abdominal cavity, ovaries but 90-95% of ectopic pregnancies are tubal pregnancy where implantation occurs in fallopian tube.
#14. Which of the following events is not associated with ovulation in human female?
In 28 days reproductive cycle, ovulation occurs on 14th day due to LH surge. In the mid cycle, the level of FSH and estrogen are also high. The female gamete is released from the ovary in secondary oocyte stage after completing meiosis I.
#15. human females, meiosis-II is not completed until
In human females, meiosis II is completed after the entry of sperm into the cytoplasm of secondary oocyte at the time of fertilisation leading to the formation of ovum and IInd polar body.
#16. Which of the following layers in an antral follicle is acellular?
Zona pellucida is a non-cellular membrane made up of glycoproteins. It is secreted by secondary oocyte in Graafian follicle.
#17. Which of these is not an important component of initiation of parturition in humans?
At the time of parturition, there is decrease in progesterone; release of prostaglandins and oxytocin, this will stimulate the contraction of smooth muscles of uterus.
#18. Capacitation refers to changes in the
Before the sperm can fertilize the ovum, it has to undergo capacitation and acrosomal reaction. Capacitation is a period of conditioning which occur in sperms starting from vagina. In this the cholesterol vesicles adhering the membrane surrounding the acrosome are removed.
#19. Hysterectomy is surgical removal of
Uterus is also called as hystera. So, removal of uterus is hysterectomy.
#20. Which of the following cells during gametogenesis is normally diploid?
Spermatogonia are diploid.
#21. The main function of mammalian corpus luteum is to produce
Corpus luteum secretes progesterone (mainly) and some estrogen.
#22. Menstrual flow occurs due to lack of
Progesterone maintains endometrium which is shed during menstruation due to low levels of progesterone.
#23. What is the correct sequence of sperm formation?
#24. Which one of the following is not the function of placenta? It
Neurohypophysis (pars nervosa) also known as posterior pituitary, stores and releases two hormones oxytocin and vasopressin
#25. In a normal pregnant woman, the amount of total gonadotropin activity was assessed. The result expected was
hCG (= human chorionic gonadotropin) stimulates corpus luteum to secrete progesterone and estrogen.
#26. Signals for parturition originate from
#27. Which one of the following statements is false in respect of viability of mammalian sperm?
Sperm is viable for 48-72 hours.
#28. The secretory phase in the human menstrual cycle is also called
#29. The Leydig cells as found in the human body are the secretory source of
LH stimulates Leydig cells to secrete androgens.
#30. The testes in humans are situated outside the abdominal cavity inside a pouch called scrotum. The purpose served is for
Spermatogenesis requires 2.5°C lower than the body temperature.
Question is very easy
we are coming with level soon.
best for revision but it should include more question for for practice so that full chapter may get revised explanation of the question and answer is the best as one can understand and make the concept strong thank you
welcome
