The submandibular ganglion is one of four parasympathetic ganglia of the head and neck. It receives parasympathetic fibers from the facial nerve.

Gross anatomy

• small ganglion suspended from the undersurface of the lingual nerve
• inferior to submandibular duct sitting on the hyoglossus muscle
• supplies secretomotor fibers to the sublingual and submandibular salivary glands

Roots

• parasympathetic root
  • from the superior salivary nucleus via the nervus intermedius and then the chorda tympani of the facial nerve
• sympathetic root
  • via the facial artery, vasomotor fibers from the superior cervical ganglion
• sensory root
  • via the lingual nerve

Branches
