A simple nerve cell, or neuron. N is the nucleus of the cell, NC is the cytoplasm, D are dendrites which are fine protoplasmic branches that create synapses that connect to another nerve cell. The neuron is connected to muscle (MU) by a nerve fiber (NF). The fiber is covered by a sheath (SH) of fat to protect it. NE is the ending of the fiber that the muscle is connected to. LB is a lateral branch of the nerve fiber.

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.
