Test: Gametogenesis & Menstrual Cycle (November 3) - Question 1

In humans, at the end end of the first meoitic division, the male germ cells differentiate into the

Detailed Solution for Test: Gametogenesis & Menstrual Cycle (November 3) - Question 1

During embryonic development the primordial germ cells migrate to the testis where they become spermatogonia. At puberty the spermatogonia proliferate rapidly by mitosis. Some undergo growth phase to become primary spermatocytes that further undergo through meiotic division I to become secondary spermatocytes. After completion of meiotic division II the secondary spermatocytes produce spermatids which differentiate to form spermatozoa.

The principal tail piece of human sperm shows the microtubular arrangement of

Detailed Solution for Test: Gametogenesis & Menstrual Cycle (November 3) - Question 2

The axial filament in the tail of human sperm has 9+2 microtubular arrangement like that of flagella and cilia.

Test: Gametogenesis & Menstrual Cycle (November 3) - Question 3

At what stage of life is oogenesis initiated in a humanfemale?

Detailed Solution for Test: Gametogenesis & Menstrual Cycle (November 3) - Question 3

Oogenesis is the process of formation of functional haploid ova from the diploid germinal cells in the ovary. Oogenesis begins during embryonic development but is completed only at puberty of the secondary oocyte with the sperm.

Test: Gametogenesis & Menstrual Cycle (November 3) - Question 4

The correct sequence of spermatogenetic stages leading to the formation of sperms in a mature human testis is

Detailed Solution for Test: Gametogenesis & Menstrual Cycle (November 3) - Question 4

In human males, the primordial germ cells divide mitotically and produce spermatogonia. Some of the spermatogonia grow into large primary spermatocytes. Each primary spermatocyte undergoes first maturation division which is a reductional (meiotic) one. Thus, the primary spermatocyte divides into two haploid daughter cells called secondary spermatocytes. Each secondary spermatocyte now undergoes second maturation division which is a mitotic one. Thus, each secondary spermatocyte gives rise to two spermatids that undergo transformation to form two sperms. Overall, two secondary spermatocytes give rise to four sperms.

Test: Gametogenesis & Menstrual Cycle (November 3) - Question 5

The middle piece of the sperm contains

Detailed Solution for Test: Gametogenesis & Menstrual Cycle (November 3) - Question 5

The middle piece of sperm contains mitochondria coiled around the axial filament. They provide energy for the movement of the sperm.

Test: Gametogenesis & Menstrual Cycle (November 3) - Question 6

During bleeding phase of menstrual cycle unfertilised secondary oocyte undergoes autolysis. The interplay of hormones then is

Detailed Solution for Test: Gametogenesis & Menstrual Cycle (November 3) - Question 6

If fertilisation does not occur, the secondary oocyte undergoes autolysis and progesterone (secreted by persistent corpus luteum) inhibits the release of LH from pituitary. Reduction of LH level causes regression of corpus luteum by autolysis and thus fall in the progesterone level in the blood. Due to deficiency of progesterone, uterine lining sloughs off causing bleeding. This whole phase is called bleeding phase.

Test: Gametogenesis & Menstrual Cycle (November 3) - Question 7

Menstrual flow occurs due to shedding of?

Detailed Solution for Test: Gametogenesis & Menstrual Cycle (November 3) - Question 7

Menstrual flow occurs due to shedding of the endometrium, which is the inner lining of the uterus.

Test: Gametogenesis & Menstrual Cycle (November 3) - Question 8

Repair of endometrium is undertaken by

Detailed Solution for Test: Gametogenesis & Menstrual Cycle (November 3) - Question 8

Estrogen secreted from ovarian follicles under the influence of FSH, causes proliferation of the endometrium of the uterine wall.

Test: Gametogenesis & Menstrual Cycle (November 3) - Question 9

Which of the following statements concerning menopause is correct?

Detailed Solution for Test: Gametogenesis & Menstrual Cycle (November 3) - Question 9

Follicular atresia means degeneration of follicles. Thus, if all follicles get degenerated at the age of 45-50 years, there will be no ovulation and hence no menstruation which leads to menopause.

Test: Gametogenesis & Menstrual Cycle (November 3) - Question 10

Study the graph carefully and correlate the hormone levels on

(i) 1-5 days
(ii) 12-14 days
(iii) 25-28 days (if the ovum is not fertilised).
