Biology : Human Reproduction

Fertilization occur in

• uterus

• ureter

• vagina

• fallopian tube

Name the hormone that has no role in menstruation

• LH

• FSH

• GH

• TSH

In spermatogenesis, reduction division of chromosome occurs during conversion of

• spermatogonia to primary spermatocytes

• primary spermatocytes to secondary spermatocytes

• secondary spermatocytes to spermatids

• spermatids to sperms

Presence of which of the following hormone in the urine confirms pregnancy?

• Progesterone

• Oestrogen

• Human chorionic gonadotropin

• Prolactin

A pregnant female delivers a baby, who suffers from stunted growth, mental retardation low intelligence quotient and abnormal skin. This is the result of

• deficiency of iodine in diet

• low secretion of growth hormone

• cancer of the thyroid gland

• over secretion of pars distalis

What is the correct sequence of sperm formation?

• Spermatid, Spermatocyte, Spermatogonia, Spermatozoa

• Spermatogonia, Spermatocyte, Spermatozoa, Spermatid

• Spermatogonia, Spermatozoa, Spermatocyte, Spermatid

• Spermatogonia, Spermatocyte, Spermatid, Spermatozoa

Menstrual flow occurs due to lack of

• progesterone

• FSH

• oxytocin

• vasopressin

Which one of the following is not the function of placenta? It

• facilitates supply of oxygen and nutrients to embryo

• secretes oestrogen

• facilitates removal of carbon dioxide and waste material from embryo

• secretes oxytocin during parturition

The correct sequence of embryonic development is

• Blastula - Morula - Zygote - Gastrula - Embryo

• Zygote - Blastula - Morula - Gastrula - Embryo

• Zygote - Morula - Blastula - Gastrula - Embryo

• Gastrula - Morula - Zygote - Blastula - Embryo

If spermatogenesis proceeds too rapidly, inhibin is released. Inhibin reduces the secretion of

• Luteinising Hormone (LH)

• Follicle Stimulating Hormone (FSH)

• Testosterone

• Interstitial Cell Stimulating Hormone (ICSH)
