What are the difference between the testes of a frog and a rat in te.pdf

The testes of frogs and rats differ in several structures, including the tunica albuginea, which consists of a thick fibrous sheet of connective tissue in both species. Interstitial cells in both secrete androsterone and testosterone, with Sertoli cells providing nutrients to mature spermatozoa and participating in steroid biosynthesis. However, frogs lack a germinal epithelial component in their seminiferous tubules, which are lined by a single layer of cuboidal cells in both species.

- 1. What are the difference between the testes of a frog and a rat in terms of tunica albuginea, interstitial cells, seminiferous tubules, basement membrane, sertoli cells Solution STRUCTURES FROG RAT TUNICA ALBUGINEA Thick fibrous sheet of connective tissue. Composed of collagen fibers and occasional smooth muscle cells. INTERSTITIAL CELLS Endocrinal in nature and secrete mainly androsterone and testosterone Major source of testosterone and also participate in steroid biosynthesis. SEMINIFEROUS TUBULES Lined by single layer of cuboidal cells. These cuboidal cells form the germinal epithelium Germinal epithelial component is absent SERTOLI CELLS Involved In providing nutrients to mature spermatozoa Capable of steroid biosynthesis and secretion of inhibin and androgen binding protein STRUCTURES FROG RAT TUNICA ALBUGINEA Thick fibrous sheet of connective tissue.
