The nerve cells that compose the ganglia are generally unipolar, and seldom bipolar; sometimes two cells are said to exist in the same envelope, constituting the twin cells of Dogiel. The cells are large and have very large nucleoli. Shown are isolated nerve cells from the frog's heart. Labels: I, Usual form. II, Twin cell. C, capsule; N,nucleus; N', nucleolus; P, process.
