[Thin branches of the human trigeminal ganglion].

Thin branches of human trigeminal ganglion were studied in material obtained during the autopsy of 78 corpses of people aged 23-69 years, using the technique of macromicroprepation and total clearing in glycerol following impregnation of nerve fibres with silver nitrate after K. Christensen or staining with Schiff reagent according to M.G. Shubich and A.G. Khodos, and on serial histotopograms, made in sagittal plane, from a material taken from 15 corpses of the people of the same age which was also impregnated after K. Christensen. Four histotopograms were used for the reconstruction of thin nerves. It was established, that trigeminal ganglion directly gave off many branches (more numerous on its outer surface as compared to the deep one), with diameters varying from 50 up to 150 microm. These branches participate in the innervation of the walls of trigeminal cavity. No connecting branches of trigeminal ganglion with plexus caroticus internus, n. petrosus major or what or any other nerve were detected.
