Q. No.The correct sequence of male sex accessory ducts beginning from testis would be:
| 1. | rete testis → vasa efferentia → epididymis → vas deferens |
| 2. | rete testis → vas deferens → vasa efferentia → epididymis |
| 3. | vas deferens → vasa efferentia → epididymis → rete testis |
| 4. | vasa efferentia → vasa deferens → epididymis → rete testis |

How many of the given statements regarding the male sex accessory ducts are correct?
| I: | The male sex accessory ducts include rete testis, vasa efferentia, epididymis and vas deferens. |
| II: | The seminiferous tubules of the testis open into the vasa efferentia through rete testis. |
| III: | The vasa efferentia leave the testis and open into epididymis located along the posterior surface of each testis. |
| IV: | The epididymis leads to vas deferens that ascends to the abdomen and loops over the urinary bladder. |
| V: | Vas deferens receives a duct from seminal vesicle and opens into urethra as the ejaculatory duct. |
| VI: | Ejaculatory ducts store and transport the sperms from the testis to the outside through urethra. |
| VII: | The urethra originates from the urinary bladder and extends through the penis to its external opening called urethral meatus. |

2. Statement I is incorrect; Statement II is correct
3. Statement I is correct; Statement II is incorrect
4. Statement I is incorrect; Statement II is incorrect
| Statement I: | A primary spermatocyte completes the first meiotic division (reduction division) leading to formation of two equal, haploid cells called secondary spermatocytes, which have only 23 chromosomes each. |
| Statement II: | The secondary spermatocytes undergo the second meiotic division to produce four equal, haploid spermatids, which have 23 chromosomes each. |

In males:
1. Only II is correct

3. I, II and III are correct
4. I, II and III are incorrect
| I: | FSH acts at the Leydig cells and stimulates synthesis and secretion of androgens. |
| II: | Androgens, in turn, stimulate the process of spermatogenesis. |
| III: | LH acts on the Sertoli cells and stimulates secretion of some factors which help in the process of spermiogenesis. |
