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.
- It is suspended from the lingual nerve by two filaments, one anterior and one posterior.
- Through the posterior filament, it receives a branch from the chorda tympani nerve.

Fibers
- The submandibular ganglion is the site of synapse for parasympathetic fibers.
- It also carries other types of nerve fibers that do not synapse in the ganglion.
- Sympathetic fibers from the external carotid plexus do not synapse in this ganglion.
- Preganglionic parasympathetic fibers from the superior salivatory nucleus synapse at this ganglion.
- Postganglionic parasympathetic fibers are secretomotor to the oral mucosa and the submandibular and sublingual salivary glands.
