The pseudounipolar cell bodies of the taste fibres conveying sensation from the anterior two-thirds of the tongue are located in which ganglion?
- A Geniculate ganglion ✓
- B Pterygopalatine ganglion
- C Submandibular ganglion
- D Nodose ganglion
Correct answer: A. Geniculate ganglion
Explanation
Taste fibres from the anterior two-thirds travel via the lingual nerve, chorda tympani and facial nerve, with their cell bodies in the geniculate ganglion, the sensory ganglion of the facial nerve located at the first genu. The pterygopalatine and submandibular ganglia are parasympathetic relay stations without taste cell bodies, and the nodose ganglion belongs to the vagus and serves taste from the posterior pharyngeal wall and valleculae.
