Which ganglion provides parasympathetic innervation to the minor salivary glands of the floor of the mouth and the sublingual and submandibular glands?

The submandibular ganglion provides parasympathetic innervation to the submandibular gland, sublingual gland, and minor salivary glands of the floor of the mouth. The pathway: preganglionic fibers travel via the facial nerve (CN VII) → chorda tympani → joins the lingual nerve → synapse in the submandibular ganglion → postganglionic fibers innervate the submandibular and sublingual glands. The OTIC GANGLION innervates the PAROTID gland (CN IX → lesser petrosal nerve → otic ganglion → auriculotemporal nerve → parotid). The GENICULATE GANGLION is a sensory ganglion of CN VII (carries taste from anterior 2/3 of tongue via chorda tympani). The PTERYGOPALATINE GANGLION innervates lacrimal and nasal glands. Key: Submandibular ganglion = submandibular + sublingual + minor salivary glands.
