Question

Which nerve is called a dentist's nerve?
A) Facial
B) Trigeminal
C) Vagus
D) Hypoglossal

Answer 1

Hint: The dental nerve is a branch of the articulator’s nerve. In addition to it, it's conjointly referred to as inferior alveolar nerve which is sometimes known as the inferior dental nerve. This nerve is complex and large.

Complete step by step answer: Inferior Alveolar Nerve (n. alveolaris inferior also known as inferior dental nerve) is the largest branch of the articulator's nerve. It descends with the inferior arteria alveolaris, initially at the lower place the Pterygoideus externus, then between the sphenomandibular ligament and also the bone of the mandibula to the articulator hiatus. It then passes forward within the articulator canal, at a lower place the teeth, as so much because the mental hiatus, wherever it divides into 2 terminal branches, incisive and mental. In simpler terms, it is that branch of the mandibular nerve which has the third branch of the trigeminal nerve which is the cranial nerve V.
-The facial nerve is called the labyrinthine segment.
-The vagus nerve is called so because it is a vagrant or wandering nerve which goes down the abdomen. So it can’t be called a dental nerve.
-Hypo refers to an under and glossal mean tongue. This nerve is located under the tongue and not teeth.
Hence, Option B-Trigeminal is the correct answer.

Note: Cranial nerves are units of the nerves that arise from the brain. There are twelve pairs of nerves. These carry impulses from the brain to the effector organs. first cranial nerve (I), the cranial nerve (II), cranial nerve (III), cranial nerve (IV), cranial nerve (V), abducent (VI), facial (VII), auditory nerve (VIII), cranial nerve (IX), nervus vagus (X), nervus accessorius (XI), hypoglossal nerve (XII) are the cranial nerves.
