Clinical link Proper functioning of the mitotic spindle is a prerequisite for chromosome transportation. Inhibition with spindle poison leads to the arrest of mitosis and cessation of cell division. Spindle poisons include colchicine, which inhibits microtubule polymerization, as well as vinca alkaloids and taxanes. #centrosome #cellbiology #cellphysiology #centrosomephysiology #nationalexittest #mbbs #physiology #usmle #usmlestep1 #medicalanimations #centrosomeandcentrioles
