- Polynucleated cell with nuclei of normal size arising from multiple karyokinetic division.
Karyokinetic figure, the one centrosome much larger than the other.
Cell in process of karyokinetic division with retention of the nucleolus during the division.
Thus the poison of various insects induces in plants the cellular new formation known as a gall-nut; a foreign body implanted in a limb may become encysted in a capsule of fibrous tissue; septic matter introduced into the abdomen will cause proliferation of the lining endo(epi)thelium; and placing an animal (salamander, Galeotti) in an ambient medium at a higher temperature than that to which it is accustomed naturally, increases the rapidity of celldivision of its epithelium with augmentation of the number of karyokinetic figures.
