Geniculate Ganglion

Nucleus: Group of neurons within the CNS 

Ganglion: Group of neurons outside the CNS 

Anatomy of the Facial Nerve 

Salivary/Facial/Abducens/Solitarus Nucleus To Geniculate Ganglion

L shaped collection of fibers and sensory neurons 

Geniculate ganglion receives fibers from

 Motor/Sensory and Parasympathetic components of Facial nerve

Geniculate Ganglion sends fibers that will innervate the 

Muscles of Facial Expresion 

along with 

Lacrimal/Submandibular/Sublingual/Tongue/Palate/Pharynx/Stapedius

External auditory meatus/Posterior belly of digastric/Stylohyoid

Clinical Significance: Geniculate Ganglion
