Morphological distinction between vasodilator and secretomotor neurons in the pterygopalatine ganglion of the cat.
We investigated whether vasodilator and secretomotor ganglion neurons are morphologically distinguishable from each other in the parasympathetic ganglion of the cat. When Cholera toxin B subunit, a retrograde tracer, was injected into the palatine gland, both large and small ganglion neurons were retrogradely labeled in the pterygopalatine ganglion. On the other hand, when the tracer was injected into gland-free areas (the upper gingiva or epidural space), all neurons labeled in the ganglion were small in size. Thus, it was assumed that small and large neurons labeled in the ganglion represented, respectively, vasomotor and secretomotor and neurons [corrected].
