The nerve continues anteriorly passing from lateral to medial under the submandibular duct and then enters the lateral margin of the mid tongue to supply sensation to the anterior two-thirds of the tongue.

What foramen does the lingual nerve pass through?

Seen from the inside, the lingual nerve is here, the inferior alveolar nerve is here. The insertion of the medial pterygoid muscle is here. The inferior alveolar nerve follows the medial pterygoid muscle down toward the mandible. It enters the mandible through this opening, the mandibular foramen.

Which muscle is supplied by 12th cranial nerve?

The hypoglossal nerve is the twelfth cranial nerve, and innervates all the extrinsic and intrinsic muscles of the tongue, except for the palatoglossus which is innervated by the vagus nerve. It is a nerve with a solely motor function.

What nerves innervate the tongue?

The hypoglossal nerve (CN XII) provides motor innervation to all of the intrinsic and extrinsic muscles of the tongue except for the palatoglossus muscle, which is innervated by the vagus nerve (CN X).

How deep is the lingual nerve?

The lingual nerve coursed on the floor of the mouth for approximately 25.43 mm before it deviated toward the tongue anywhere between the mesial of M1 and distal of M2. Thirteen lingual nerves were found to loop around the submandibular duct for an average distance of 6.92 mm (95\% CI: 5.24 to 8.60 mm).

The Lingual nerve (LN) is a branch of the mandibular division of the trigeminal nerve (V3) that is responsible for general somatic afferent (sensory) innervation. It supplies the mucous membranes of the mandibular lingual gingiva, floor of the mouth and the ipsilateral two-thirds of the tongue.

What is the lingual nerve?

The lingual nerve is one of the sensory branches of the mandibular division of the trigeminal nerve. [5] It contains general somatic afferent nerve fibers and, after chorda tympani joins it, also carries general visceral efferent nerve fibers and special visceral afferent fibers.
