The submandibular ganglion (or submaxillary ganglion in older texts) is part of the human autonomic nervous system. It is one of four parasympathetic ganglia of the head and neck. (The others are the otic ganglion, pterygopalatine ganglion, and ciliary ganglion).

Location and relations
The submandibular ganglion is small and fusiform in shape. It is situated above the deep portion of the submandibular gland, on the hyoglossus muscle, near the posterior border of the mylohyoid muscle.
The ganglion 'hangs' by two nerve filaments from the lower border of the lingual nerve (itself a branch of the mandibular nerve, CN V3). It is suspended from the lingual nerve by two filaments, one anterior and one posterior. Through the posterior of these it receives a branch from the chorda tympani nerve which runs in the sheath of the lingual nerve.
Fibers
Like other parasympathetic ganglia of the head and neck, the submandibular ganglion is the site of synapse for parasympathetic fibers and carries other types of nerve fiber that do not synapse in the ganglion. In summary, the fibers carried in the ganglion are:
- Sympathetic fibers from the external carotid plexus, via the facial artery and its branches. These do not synapse in this ganglion.
- Preganglionic parasympathetic fibers from the superior salivatory nucleus of the Pons, via the chorda tympani and lingual nerve, which synapse at this ganglion.
- Postganglionic parasympathetic fibers to the oral mucosa and the submandibular and sublingual salivary glands.They are secretomotor to these glands. Some of the postganglionic fibers reach the sublingual gland after they re-enter the lingual nerve.[1]

- The submandibular ganglion is fusiform, 2–3 mm long, and is anatomically associated with the lingual nerve as it crosses the superior part of the hyoglossus muscle. Preganglionic axons leave the facial nerve in the chorda tympani nerve and join the lingual nerve to reach the submandibular ganglion (Mitchell, 1953a; Diamant and Wiberg, 1965).
- The submandibular ganglion is small and fusiform in shape. It is situated above the deep portion of the submandibular gland, on the hyoglossus muscle, near the posterior border of the mylohyoid muscle. The ganglion 'hangs' by two nerve filaments from the lower border of the lingual nerve (itself a branch of the mandibular nerve, CN V 3).
- The branches of the submandibular ganglion are: 5 to 6 branches, which supply the submandibular gland Other fibres join the lingual nerve to supply the sublingual and anterior lingual glands. Surgical Planes of the Submandibular Region
