Cytoplasm bridges

WebWhat are cytoplasmic bridges? A thin, direct cytoplasmic connection between two cells through which large molecules can pass (unlike gap junctions). Common in plants (plasmodesmata) but rare in animals except between nurse cells and developing gametes. Why cytokinesis is incomplete in spermatogenesis? WebTrue intercellular bridges affording protoplasmic continuity between cells are reported as a normal occurrence in the clusters of spermatocytes and spermatids in the germinal epithelium of the testis. Similar bridges are found in the groups of cnidoblasts in the ectoderm of Hydra.
