Secretomotor fibers to submandibular ganglion are carried by which nerve?
Submandibular ganglion is a parasympathetic peripheral ganglion. It is a relay station for secretomotor fibres to the submandibular and sublingual salivary glands. Topographically, it is related to the lingual nerve, but functionally, it is connected to the chordatympani branch of the facial nerve (chorda tympani). The motor or parasympathetic fibres pass from the lingual nerve to the ganglion through the posterior root. These are preganglionic fibres that arise in the superior salivatory nucleus and pass through the facial nerve, the chorda tympani, and the lingual nerve to reach the ganglion.
