Synonyms:
- genicular ganglion
The geniculate or genicular ganglion contains fibers for taste and somatic sensation and is located in the petrous temporal bone.
Gross anatomy
It is located at the first genu of the facial nerve at the anterior most part of the Fallopian canal at the junction between the labyrinthine and tympanic segments. In this ganglion the taste fibers carried to it by the nervus intermedius synapse.
Fibers in:
- facial nerve (labyrinthine segment)
- nervus intermedius
Fibers out:
- facial nerve (tympanic segment)
- greater superficial petrosal nerve
- lesser petrosal nerve
- external petrosal nerve
Relations
- anteromedially: internal carotid artery
- anterolaterally: foramen spinosum
- posteriorly: superior semicircular canal 3
