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

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'.

A Correct answer
Explanation

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.

Oophorocystosis is

  1. Disorder of female reproductive system

  2. Stage in the production of ovum

  3. Disorder in male reproductive system

  4. Stage in the production of sperms
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Oophorocystosis is the disorder of ovaries in which formation of cysts. These are small egg follicles that don't grow to ovulation and are the result of altered hormone levels.

So the correct option is 'Disorder of female reproductive system'.

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

  1. Prostate gland

  2. Seminal vesicle

  3. Cowper's gland

  4. Bartholin's gland
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

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'.

In human adult females oxytocin

  1. stimulates pituitary to secrete vasopressin

  2. causes strong uterine contractions during parturition

  3. is secreted by anterior pituitary

  4. simulates growth of mammary glands.

B Correct answer
Explanation

In human adult female oxytocin is a hormone released by the pituitary gland (neurohypophysis), that causes contraction of the uterine muscles during labour.

Which event becomes possible due to formation of egg membrane?

  1. Sperm can enter into ovum

  2. Prevents entry of other sperms in to ovum

  3. Prevents the process of fertilization so pregnancy is prevented

  4. Makes fertilization process possible and causes pregnancy
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation
The sperm that successfully reaches the secondary oocyte is initially prevented entry by both corona radiata and the zona pellucida. When the sperm reaches the corona radiata, their motility allows the sperm to push through the cell layers. After the sperm has made a pathway through the corona radiata, they release digestive enzymes from their acrosomes to penetrate the zona pellucida. When one sperm successfully penetrates the zona pellucida and its nucleus enters the secondary oocyte, immediate changes occur in both the zona pellucida and the oocyte, so that no other sperm can enter. In essence, the zona pellucida hardens, preventing entry of other sperms into the ovum. 

So, the correct answer is option B.

  1. fat and low in proteins

  2. proteins and low in fat

  3. proteins, antibodies and low in fat

  4. proteins, fat and low in antbodies.

C Correct answer
Explanation

After birth, the first milk released by mammary glands is called colostrum. It is released for 2-3 days. It is thin, yellowish fluid containing cells from the alveoli of glandular tissue of mammary glands and is rich in protein, antibodies, but low in fat.

Ova are released from ovary under the effect of LH-Hormones, after which of the following event.

  1. Before meiosis and production of polar body

  2. Meiosis-I and before production of polar body

  3. Meiosis and at the time of production of polar body

  4. Meiosis II and after the formation of polar body
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Primary oocyte undergoes meiosis 1 and the first polar body and secondary oocyte are produced. Secondary oocyte which is arrested at metaphase 2 develops into the graffian follicle and after the secretion of the LH hormone occurs which leads to ovulation.

So the correct option is 'meiosis II and after the formation of the polar body'.
