frogs testes do not passes a. leyding b. seminiferous tubules c. sertolicells d. sertoli cells
Answers
Answer:
Explanation:
Seminiferous tubule
1. In frog,The mature spermatozoon is dependent upon external sources of nutrition so that it joins from 25 to 40 other spermatozoa, all of whose heads may be seen converging into the cytoplasm of a relatively large, columnar-type basal cell known as the Sertoli cell. This is functionally a nurse cell.
2. Spermatozoa are carried passively down the ureter to the slight dilation near the cloaca, known as the seminal vesicle. Within the vesicle the spermatozoa are stored briefly in clusters until amplexus and oviposition occur.
3. The spermatozoa are produced in subdivisions of the testes known as seminiferous tubules. These are closely packed, oval-shaped sacs, which are separated from each other by thin partitions (septula) of supporting (connective) tissue known as interstitial tissue.
So, the correct answer is 'None of the above'.
