Question 1
1 / -0

Bartholin's glands are situated _________________.

A
On the either side of Vagina in Humans

B
On either side of Vas deferens in Humans

C
On either side of Penis in Humans

D
On either side of Fallopian tube in Humans

Solution

Bartholin's glands are a pair of small glands situated on each side of the vaginal opening in human females. They secrete a thick, viscid secretion for lubrication during copulation.
Question 2
1 / -0

The given figure is of human female reproductive system. Identity the parts labelled as A, B, C and D and select the select option.

A
A-Oviduct, B-Utems, C-Ovarian ligament, D-Ovary

B
A-Cervix, B-Uterus, C-Ovary, D-Tumour

C
A-Utems, B-Uterine cavity, C-Oviductal funnel, D-Ovary

D
A-Cervix, B-Uterine cavity, C-Fallopian tube, D-Ovary

Solution

Cervix is the lowermost part of the uterus and is made up of strong muscles. The function of the cervix is to allow the flow of menstrual blood from the uterus into the vagina and directs sperms. The uterine cavity or the cavity of the uterus is a triangular shaped structure and is located in a woman's lower abdomen, between the bladder and the rectum. it helps in nurturing the fertilized ovum that develops into the fetus and holding it till the baby is mature enough for birth. The Fallopian tube (tubular having three parts Fimbriae – finger-like, ciliated projections which capture the ovum from the surface of the ovary. Infundibulum – funnel-shaped opening near the ovary to which fimbriae are attached. Ampulla – widest section of the uterine tubes) or the oviduct transports the egg from the ovary to the uterus. The ovaries (oval-shaped and are approximately 1 1/2 inches in length) or female sex organs produce oocytes (eggs) for fertilization and they produce the reproductive hormones, estrogen and progesterone.
So, the correct option is 'A-Cervix, B-Uterine cavity, C-Fallopian tube, D-Ovary'.
Question 3
1 / -0

The given figure depicts a diagrammatic sectional view of the human female reproductive system. Which set of three parts out of I-VI have been correctly identified?

A
(II) Endometrium, (III) Infundibulum, (IV) Fimbriae

B
(III) Infundibulum, (IV) Fimbriae, (V) Cervix

C
(IV) Oviducal funnel, (V) Uterus, (V) Cervix

D
(I) Perimetrium, (II) Myometrium, (III) Fallopian tube

Solution

The female reproductive organ consists of a pair of ovaries (produce egg or ovum)
The uterus - or the womb - for development of the foetus
The oviducts (a pair) - transfer, push egg towards the uterus and then the developing zygote after fertilization.
The oviducts end into a broad funnel like structure called the infundibulum (III), that is lined by finger like projections called the fimbriae (IV). The movement of the infundibulum and the fimbriae results in picking up of the egg into the oviduct.
The uterus opens into a narrow region called the cervix (V)
So, the correct answer is '(III) Infundibulum, (IV) Fimbriae, (V) Cervix'
Question 4
1 / -0

In spermatogenesis the phase of maturation involves

A
the growth of spermatogonia into primary spermatocyte

B
the formation of spermatogonia from gonocytes through mitosis

C
the formation of spermatids from primary spermatocytes through meiosis

D
the formation of oogonia from the spermatocytes through meiosis.

Solution

Spermatogenesis is the process of maturation of sperms from primary spermatocyte by the process of meiosis. The primary spermatocytes (derived from the spermatogonia) periodically undergo meiosis to form secondary spermatocytes. The secondary spermatocytes undergo second meiosis to form four equal haploid spermatids.
So, the correct answer is ' the formation of spermatids from primary spermatocytes through meiosis'.
Question 5
1 / -0

Prostate glands are located below

A
gubernaculum

B
seminal vesicles

C
epididymis

D
bulbourethral glands.

Solution

The prostate gland (small and walnut-shaped) is located beneath the seminal vesicle and secretes a fluid that nourishes and protects sperm. The prostate is just in front of the rectum. The urethra runs through the center of the prostate, from the bladder to the penis, letting urine flow out of the body.
So, the correct answer is 'Seminal vesicles'.
Question 6
1 / -0

How many sperms are formed from a secondary spermatocyte?

A
4

B
8

C
2

D
1
Solution
Correct option: C
Explanation:
The spermatogonia undergo mitotic division to form the primary spermatocyte.
Then, each primary spermatocyte undergoes meiotic division to form 2 secondary spermatocytes.
Then, each of the two secondary spermatocytes undergoes a second meiotic division to form 2 spermatids.
The spermatids formed undergo spermiogenesis to transform into mature spermatozoa.
Hence, "2" sperms are formed from a secondary spermatocyte.
Question 7
1 / -0

In spermatogenesis, reduction division of chromosome occurs during conversion of ____________________.

A
Spermatogonia to primary spermatocytes

B
Primary spermatocytes to secondary spermatocytes

C
Secondary spermatocytes to spermatids

D
Spermatids to Sperms

Solution

During spermatogenesis, at the end of first maturation division (reductional division or meiosis), the primary spermatocyte divides into two haploid daughter cells called secondary spermatocytes.
Question 8
1 / -0

The female external genitalia include
(i) Ovary
(ii) Mammary gland
(iii) Mons pubis
(iv) Clitoris
(v) Labia majora

A
(i) and (ii)

B
(ii) and (iii)

C
(iii), (iv) and (v)

D
(ii), (iii) and (v)
Question 9
1 / -0

The phase of menstrual cycle in humans that last for 7-8 days, is ____.

A
Follicular phase

B
Ovulation phase

C
Luteal phase

D
Menstruation
Question 10
1 / -0

A human female reaches menopause around the age of

A
50 years

B
17 years

C
70 years

D
25 years.
Solution
A.Correct option A

B.Explanation for the correct option:
- Menopause marks the end of a woman's fertility and the cease of the menstrual cycle. The ovaries stop producing hormones and in humans, the menstrual cycle ceases at around 50 years of age.
- So, the correct answer is '50 years'.
