Multiple choice female reproductive structure reproductive system of human hormones, homeostasis, and reproduction human physiology biology

The secretion of progesterone by corpus luteum is initiated by

  1. FSH

  2. LH

  3. MSH

  4. Thyroxine
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The luteal phase is marked by the increased concentration of the luteinizing hormone. The LH stimulates the corpus luteum to secrete progesterone which helps in the maintenance of the pregnancy by increasing the thickening of the cell lining of the endometrial wall. 

Thus, the correct answer is option B.

An unfertilized human egg would have

  1. Two X - chromosome

  2. One X - chromosome

  3. One Y - chromosome

  4. Both X and Y - chromosome
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The gametes are the haploid cells which are produced by the meiotic division. The egg is the female gamete which is produced through oogenesis. The gametes are haploid and contain only one set of the chromosome. So, the egg cell contains the 22 autosomes and one X chromosome. Since the female somatic cell contains two X chromosome, there will be only one X chromosome in the gamete.

Thus, the correct answer is option B.

In a normal pregnant woman, the amount of total gonadotropin activity was assessed. The result expected was

  1. High level of circulating FSH and LH in the uterus to stimulate implantation of the embryo.

  2. High level of circulating hCG to stimulate endometrial thickening.

  3. High level of FSH and LH in uterus to stimulate endometrial thickening.

  4. High level of circulating hCG to stimulate estrogen and progesterone synthesis.

B,D Correct answer
Explanation

After implantation of blastocyst (pregnancy), the placenta produces the hormone hCG (human chorionic gonadotropin) hCG promotes the maintenance of the corpus luteum to secrete the hormone progesterone and estrogen. High levels of hCG stimulates endometrial thickening also.

Some important events in the human female reproductive cycle are given below. Arrange the events in a proper sequence.
A : Secretion of FSH
B : Growth of corpus luteum
C : Growth of the follicle and oogenesis
D : Ovulation 
E : Sudden increase in the levels of LH

  1. $C\rightarrow A\rightarrow D\rightarrow B \rightarrow E$
  2. $A\rightarrow C\rightarrow E\rightarrow D \rightarrow B$
  3. $A\rightarrow D\rightarrow C\rightarrow E \rightarrow B$
  4. $B\rightarrow A\rightarrow C\rightarrow D \rightarrow E$
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The sequence is: FSH secretion (A) leads to follicle growth (C), which leads to high estrogen and LH surge (E), causing ovulation (D), followed by the formation of the corpus luteum (B).

A female gland corresponding to prostate gland of males is

  1. Bartholin's gland

  2. Bulbourethral gland

  3. Clitoris

  4. None of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The prostate gland in males contributes to seminal fluid. The female equivalent, often cited as having similar embryological or functional roles, is the Skene's gland (paraurethral gland), not Bartholin's or Bulbourethral glands.

Which one of the following is the most likely root cause why

menstruation is not taking place in regularly cycling human female ?

  1. Retention of well-developed corpus luteum

  2. Fertilization of the ovum

  3. Maintenance of the hypertrophical endometrial lining

  4. Maintenance of high concentration of sex-hormones in the blood stream
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Menstruation occurs when the corpus luteum degenerates, leading to a drop in progesterone. If fertilization occurs, the corpus luteum is maintained by hCG, preventing menstruation.

Accessory glands associated with genital organs of female are
(a) Vestibular or Bartholin's
(b) Cowper's
(c) Ampullary
(d) Vesicular

  1. a, b

  2. a only

  3. b, c

  4. d only

  5. c only
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The female external genitalia contains vulva, Bartholin's gland, and clitoris. Further vulva contains mons pubis, labia majora, and labia minora. Bartholin's gland help in lubrication of vagina and clitoris is a tiny finger-like structure which helps in stimulation.

So, the correct option is 'a only'.

Which group represents external genitalia of human female?

  1. Labium minora, labium majora, vagina

  2. Labium minora, labium majora, oviduct

  3. Labium minora, labium majora, cervix

  4. Labium minora, labium majora, clitoris
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The external genitalia of human female consists of:

Mons pubis - It is the anterior most part and is covered with pubic hair and skin. 
Clitoris - Present posterior to mons pubis and is homologous to the glans penis as it contains the erectile tissues. 
Labium majora - Large fleshly folding and is covered with sebaceous glands. It is considered to be homologous to scrotum. 
Labium minora - Small fleshly folding which are homologous to penile urethra.
Thus, the correct answer is 'Labium minora, labium majora, clitoris'.
