ELECTRONMICROSCOPICAL INVESTIGATION OF THE SMALL NEURONS IN TRIGEMINAL GANGLION

Trigeminal ganglion (TrG) in its essence represents gathering of pseudounipolar neurons, situated in trigeminl impression of the petrosal part of the temporal bone, wrapt in connecting tissue "sleeve" of trigeminal cavity of the dura and aracknoid maters in vicinity to back end of cavernous sinus. Peripheral tentacles of pseudounipolar cells participate in formation of the first, second and receptive part of the fifth cerebral nerve, and central tentacles form the receptive root entering in middle cerebellar peduncle aside the brainstem.
