Quick Summary

The submandibular ganglion is a key component of the parasympathetic nervous system, specifically involved in regulating salivary glands. It receives preganglionic parasympathetic fibers from the superior salivatory nucleus via the facial nerve's intermediate nerve and chorda tympani branch. Postganglionic fibers from the submandibular ganglion then innervate the submandibular and sublingual salivary glands. These glands produce mixed secretions, predominantly serous in nature for the submandibular glands and mucous for the sublingual glands. The parasympathetic nervous system's control over these glands is crucial for functions like moistening food and initiating digestion.123
