WebA peritubular myoid (PTM) cell is one of the smooth muscle cells which surround the seminiferous tubules in the testis. [1] [2] These cells are present in all mammals but their organization and abundance varies between species. [2] The exact role of PTM cells is still somewhat uncertain and further work into this is needed. WebDefinition. 1 / 28. Mitosis is cell division into two identical daughter cells (cell division). PHASES: Interphase: DNA appears as uncoiled chromatin and nuclear membrane is intact. Prophase: chromosomes condense and become visible. -nuclear membrane breaks down. -centrosomes move toward opposite poles. Metaphase: chromosomes are lined up at ...

WebThe cells in these animals are joined by junctional complexes as are epithelial cells. On the other hand, several cellular layers exist in the lamina propria of the seminiferous tubule in the human and some other animals. Myoid cells contain abundant actin filaments which are distributed in the cells in a species-specific manner.
