Effects of light and dark on photoreceptors in the polychaete annelid Nereis limnicola.

abstract：:Within seminiferous tubules, Sertoli cells form three types of actin-filament-containing cell junctions, viz., tight junctions, ectoplasmic specializations, and tubulobulbar complexes. These Sertoli cell junctions are involved in the formation of the blood-testis barrier, germ cell translocation, and the release of sp...
