Descripción

In passing through the jugular foramen, the glossopharyngeal nerve [IX] presents two ganglia, the superior and the inferior :

  • The Superior Ganglion (ganglion superius; jugular ganglion) is situated in the upper part of the groove in which the nerve is lodged during its passage through the jugular foramen. It is very small, and is usually regarded as a detached portion of the petrous ganglion.

The Inferior Ganglion (ganglion petrosum; petrous ganglion) is larger than the superior and is situated in a depression in the lower border of the petrous portion of the temporal bone.
