Morphology, topography and cytoarchitectonics of the otic ganglion in Egyptian spiny mouse (Acomys cahirinus, Desmarest).

Using the thiocholine method of Koelle and Friedenwald and histological techniques, the otic ganglion in Egyptian spiny mouse (Acomys cahirinus, Desmarest) was studied. The ganglion was found to be a single oval cluster of neurocytes, situated at the medial and posterior surface of the mandibular nerve just above the maxillary artery. The ganglion is composed of typical ganglionic neurons in compact arrangement without a thick connective-tissue capsule.
