The pterygopalatinum ganglion is a parasympathetic ganglion. It is located in the pterygopalatine fossa, caudal to the nervus mandibularis and laterally to the foramen sphenopalatinum, here it is connected to the nn. pterygopalatini. It has a flat triangular or heart shape and is reddish-gray in color. It contains about 50,000 parasympathetic neurons (it is therefore the largest parasympathetic ganglion in the head region).
The petrosus major nerve enters it from behind as a parasympathetic radix , the fibers of the radix sympathetica come via the petrosus profundus nerve from Budge's ciliospinal center, as the radix sensitiva fibers leave the ganglion via the maxillaris nerve . From the ganglion emerge rr. nasales posteriores superiores, rr. nasales posteriores inferiores, n. palatinus major and nn. palatinii minores, yr. tonsillares, rr. orbitales and n. pharyngeus . Interpolation takes place here - switching to the second neuron of the parasympathetic pathway (part of the path of parasympathetic innervation of the lacrimal gland).
