Which nerve provides general somatic sensation to the anterior two-thirds of the tongue?
Answer: Lingual nerve (CN V3)
The lingual nerve, a branch of the mandibular division of the trigeminal nerve (V3), carries general somatic sensation (touch, pain, temperature) from the anterior two-thirds of the tongue.
The parotid duct (Stensen's duct) opens into the oral vestibule opposite which tooth?
Answer: Upper second molar
The parotid duct pierces the buccinator muscle and opens at the parotid papilla on the buccal mucosa opposite the upper second molar.
Which muscle of mastication is the most powerful elevator of the mandible?
Answer: Masseter
The masseter is the most powerful elevator of the mandible; it has superficial and deep heads that together generate the greatest occlusal force among the masticatory muscles.
The submandibular duct (Wharton's duct) opens at which structure in the oral cavity?
Answer: Sublingual caruncle adjacent to the lingual frenulum
Wharton's duct opens at the sublingual caruncle (papilla), a small elevation on either side of the lingual frenulum on the floor of the mouth.
Which foramen on the medial aspect of the mandibular ramus transmits the inferior alveolar nerve and vessels?
Answer: Mandibular foramen
The inferior alveolar nerve and artery enter the mandibular canal through the mandibular foramen, located on the medial surface of the ramus, guarded anteriorly by the lingula.
Taste sensation from the anterior two-thirds of the tongue is conveyed by which nerve?
Answer: Chorda tympani (CN VII)
The chorda tympani, a branch of the facial nerve (CN VII), carries special visceral afferent (taste) fibres from the anterior two-thirds of the tongue and travels with the lingual nerve in the infratemporal fossa.
Which lymph nodes receive primary drainage from the tip of the tongue?
Answer: Submental nodes
The tip of the tongue drains primarily to the submental lymph nodes (between the anterior bellies of the digastric muscles), which then drain to the deep cervical chain.
