Find the incorrect statement
1. scrotum helps in maintaining low temperature of the testes 2-2.5 less than normal, necessary for spermatogenesis
2. Each testis has about 250 testicular lobules
3. Transfer of sperms into female genital tract is insemination
4. Seminiferous tubules open into rete testis through vasa efferentia
Oogenesis differs from spermatogenesis in a number of aspects. One of the following is however a similarity between the two
1. Growth phase is prolonged in both of them an starts before birth
2. Both give rise to non-motile gametes
3. Both produce equal number of gametes
4. Both occur inside primary sex organ
Which of the following occur during pre ovulatory phase?
a. Formation of corpus heamorrhagicum
b. Luteal phase
c. Secretory phase
d. Follicular phase
e. Proliferative phase
1. d & e only
2. a, b & c only
3. a, b & e only
4. c & d only
The following graph of relative concentrations of the four hormones present in the blood plasma of a woman during menstrual cycle. Identify the hormones:
A B C D
1. FSH Progesterone LH Oestrogen
2. LH Progesterone FSH Oestrogen
3. FSH Oestrogen LH Progesterone
4. LH Oestrogen FSH Progesterone
Which of the following cell completes the first meiotic division leading to the formation of two equal, haploid cells?
1. Spermatogonium
2. Primary spermatocytes
3. Secondary spermatocytes
4. Spermatids
Match the column and choose the correct answer.
Column-I Column-II
a. Hypothalamus (i) Sperm lysin
b. Acrosome (ii) Estrogen
c. Graffian follicle (iii) Relaxin
d. Leydig cells (iv) GnRH
e. Parturition (v) Testosterone
1. a(iv), b(i), c(ii), d(iii), e(v)
2. a(ii), b(i), c(iv), d(iii), e(v)
3. a(ii), b(i), c(v), d(iv), e(iii)
4. a(iv), b(i), c(ii), d(v), e(iii)
Which of the following statement is incorrect about menstrual cycle?
1. LH Surge causes ovulation at the mid of the menstrual cycle
2. Corpus luteum is formed by graafian follicle on the next day of ovulation under the influence of progesterone
3. Abrupt fall in progesterone is the instant cause of menstruation
4. Corpus luteum remains active about 10-12 days in a normal menstruating female
No new follicles develop in the luteal phase of the menstrual cycle because :
1. | Follicles do not remain in the ovary after ovulation |
2. | FSH levels are high in the luteal phase |
3. | LH levels are high in the luteal phase |
4. | Both FSH and LH levels are low in the luteal phase |
Which of the following depicts the correct pathway of transport of sperms?
1. | Rete testis →Efferent ductules → Epididymis → vas deferens |
2. | Rete testis → Epididymis → Efferent ductules → vas deference |
3. | Rete testis → Vas deference → Efferent ductules → Epididymis |
4. | Efferent ductules →Rete testis → Vas deference →Epididymis |
An oocyte is released from the ovary under the influence of LH
1. After completing meiosis and before polar body are released
2. After completing meiosis I and before release of polar body
3. After completing meiosis
4. After completing meiosis I and after release of polar body
