Petrosal Ganglion, Ganglion of Andersch, is formed by the glosso-pharyngeal nerve, shortly after it emerges from the jugular fossa. From this ganglion, M. Jacobson of Copenhagen traced an anastomosing loop through the cavity of the tympanum, which left branches there, and was thence reflected downwards to join the Vidian nerve. - See Otic Ganglion. This has been called the Nerve of Jacobson, Tympanic branch of the glosso-pharyngeal, and the inosculation, Jacobson’s Anastomosis.
