How many seminiferous tubules will be there per testicular lobule?
| 1. | 1 to 3 | 2. | 500 |
| 3. | 1000 | 4. | At maximum, 4 |
Leydig cells are present in
| 1. | Seminiferous tubules |
| 2. | Outside seminiferous tubules |
| 3. | Scrotal wall |
| 4. | With male germ cells |
| 1. | These seminiferous epithelium contains only proliferative cells |
| 2. | Functional compartmentalization of the seminiferous epithelium depends on tight junctions |
| 3. | The interstitial tissue contains few capillaries |
| 4. | The seminiferous epithelium contains numerous capillaries |
| 1. | About 200 seminiferous tubules are present in testis lobule |
| 2. | Epididymis is located along the anterior surface of each testis |
| 3. | Vas deferens ascends to the abdomen and loops over the bladder |
| 4. | Ducts of seminal vesicles open at the urethral meatus |
| a. | Interstitial spaces of testis contain Leydig cells and other immunologically competent cells. |
| b. | Testes are situated inside the abdominal cavity within a pouch called scrotum. |
| c. | The scrotum helps in maintaining the low temperature necessary for spermatogenesis. |
| d. | Each lobule of testis contains 250 seminiferous tubules in which sperms are produced. |
| Assertion (A): | Interstitial spaces outside the seminiferous tubule have blood vessels and sertoli cells. |
| Reason (R): | Sertoli cells provide nutrition to the germ cells. |
| 1. | Both (A) and (R) are true and (R) is the correct explanation of (A). |
| 2. | Both (A) and (R) are true but (R) is not the correct explanation of (A). |
