Question 1
1 / -0

Component of seminal vesicles that provides a forensic test for rape is?

A
Phosphorycholine

B
Prostaglandin

C
Frustose

D
Citric acid

Solution

Seminal vesicles contains the sugar fructose, a coagulating enzyme, ascorbic acid and a hormone like prostaglandins.
Fructose provides energy to the spermatozoa for swimming, it is not produced anywhere else in the body, provides a forensic test for rape. Its presence in the female's genital tract confirms sexual intercourse.
So, the correct answer is 'Fructose'
Question 2
1 / -0

The first sign of growing human foetus in uterus may be noticed by

A
Listening heart sound

B
Movement of foetus

C
Development of limbs and digits

D
None of the above

Solution

Growing human develops heart at a very early stage around the fifth week of the gestation period and it started working so it is very common that heartbeat is detected and it is considered as the growth sign.
So the correct option is 'Listening heart sound'.
Question 3
1 / -0

In a human foetus the limbs and digits develop after

A
8 weeks

B
Fifth month

C
First trimester

D
12 weeks
Solution
- In the human fetus, limbs are initially undifferentiated mesoderm which is covered with the epithelium. At the end of week 4, the limb bud primordia appear as small elevations.
- However, most of the development in the limbs occurs at week 6 but cannot be clearly differentiated.
- At 8 weeks of gestation, the feet and hands can be distinguished, but may still be webbed. A couple of weeks later, one can identify the limbs and digits clearly.
Thus, the limbs and digits in a human fetus begin to develop after '8 weeks'.
Question 4
1 / -0

Each secondary spermatocyte after second meiotic division produces

A
Four haploid spermatids

B
Only one haploid spermatid

C
Two haploid spermatids

D
Two diploid spermatids

E
Four diploid spermatids

Solution

Spermatogenesis is the meiotic division of spermatogonia to give rise to spermatozoa. The diploid spermatogonium mitotically gives rise to the diploid primary spermatocytes which further, via meiosis, give rise to haploid secondary spermatocytes, spermatids, and spermatozoids. The secondary spermatocytes produced by the primary spermatocytes further give rise to two haploid spermatids via meiosis.
So, the correct answer is 'Two haploid spermatids'.
Question 5
1 / -0

Which of the following implants in the lining of uterus?

A
Zygote

B
Gastrula

C
Blastocyst

D
Morula

Solution

Implantation involves the movement of a developing embryo to the uterine wall and its attachment to the same. The embryo is in its blastocyst stage, that is, the 16-celled stage when it gets implanted on the uterine wall and further development of the embryo takes place attached to the uterine wall.
So, the correct answer is 'Blastocyst'.
Question 6
1 / -0

Which one of these is not an accessory gland in male reproductive system?

A
Prostate gland

B
Seminal vesicle

C
Cowper's gland

D
Bartholin's gland

Solution

Bartholin's glands are present in the female reproductive system and are homologous to the bulbourethral glands in males. Their basic function is to secrete mucus and lubricate the vagina. They are basically two pea-sized glands and are also known as greater vestibular glands and are present symmetrically in the posterior region of the vaginal opening.
The correct answer is 'Bartholin's gland'.
Question 7
1 / -0

Identify the complete and correct sequence in the passage of spermatozoa.

A
Seminiferous tubules $$\rightarrow$$ Rete testis $$\rightarrow$$ Vasa efferentia $$\rightarrow$$ Vas deferens $$\rightarrow$$ Epididymis $$\rightarrow$$ Ejaculatory duct $$\rightarrow$$ Urethra $$\rightarrow$$ Vagina of female

B
Seminiferous tubules $$\rightarrow$$ Rete testis $$\rightarrow$$ Vasa efferentia $$\rightarrow$$ Epididymis $$\rightarrow$$ Vas deferens $$\rightarrow$$ Ejaculatory duct $$\rightarrow$$ Urethra $$\rightarrow$$ Vagina of female

C
Seminiferous tubules $$\rightarrow$$ Rete testis $$\rightarrow$$ Vasa efferentia $$\rightarrow$$ Epididymis $$\rightarrow$$ Urethra $$\rightarrow$$ Vagina of female

D
Seminiferous tubules $$\rightarrow$$ Rete testis $$\rightarrow$$ Vasa efferentia $$\rightarrow$$ Ejaculatory duct $$\rightarrow$$ Vagina of female

Solution

The spermatozoa released from the seminiferous tubules move to the rete testis, then via the vasa efferentia, they move to the epididymis where they are stored. On the event of copulation, they travel through the vas deferens into the ejaculatory duct then the urethra and finally land in the vagina of the female
So, the correct answer is 'Seminiferous tubules
→ Rete testis → Vasa efferentia → Epididymis → Vas deferens → Ejaculatory duct →Urethra → Vagina of female'.
Question 8
1 / -0

Identify the correct passage of spermatozoa in the male human reproductive system.
(a) Vas deferens
(b) Epididymis
(c) Urethra
(d) Vasa efferentia
(e) Ejaculatory duct
(f) Seminiferous tubules.

A
b$$\rightarrow$$ d $$\rightarrow$$ f $$\rightarrow$$ c $$\rightarrow$$ a $$\rightarrow$$ e

B
b $$\rightarrow$$ c $$\rightarrow$$ e $$\rightarrow$$ f $$\rightarrow$$ a $$\rightarrow $$ d

C
f$$\rightarrow$$ d $$\rightarrow$$ b $$\rightarrow$$ a $$\rightarrow$$ e $$\rightarrow$$ c

D
f$$\rightarrow$$ b $$\rightarrow$$ a $$\rightarrow$$ d $$\rightarrow$$ e $$\rightarrow$$ c

Solution

In the male reproductive system, spermatozoa released from the seminiferous tubules move to the rete testis, then via the vasa efferentia, they move to the epididymis where they are stored. On the event of copulation, they travel through the vas deferens into the ejaculatory duct and are then released via the urethra.
So, the correct answer is 'f→→ d →→ b →→ a →→ e →→ c'.
Question 9
1 / -0

The progesterone level rises in which phase of menstrual cycle?

A
Menstrual phase

B
Proliferative phase

C
Secretory phase

D
Maturation phase

Solution

The most important funtion of progesterone is to prepare the uterus for pregnancy, i.e., implantation and support of a fertilized egg. This hormone is produced increasingly by the corpus luteum in the luteal phase after the rupture of the follicle to release the ovum. Progesterone also stimulates the lining of the uterus to secrete certain hormones for the thickening and maintenance of the endometrium. For this reason the luteal phase is also called the 'secretory phase' where progesterone levels reach a peak. So, the correct answer is 'Secretory phase'.
Question 10
1 / -0

Which of the following layers is acellular in antral follicle?

A
Granulosa

B
Theca interna

C
Stroma

D
Zona pellucida

Solution

The antral follicle or the secondary follicle is identified when a fluid-filled cavity (antrum) is formed adjacent to the oocyte. The zona pellucida is basically a glycoprotein layer which surrounds the oocyte and separates it from the granulosa cells. This layer primarily contains enzymes required for the penetration of the sperm.
So, the correct answer is 'Zona pellucida'.
