The Inferior Alveolar Nerve is a branch of the mandibular nerve, which is part of the trigeminal nerve system. It primarily provides sensory innervation to the lower teeth, gums, and part of the lower lip. This nerve travels through the mandibular canal within the jawbone, making it crucial for dental procedures and pain sensation in the lower jaw. In addition to sensory functions, the Inferior Alveolar Nerve also gives off the mylohyoid nerve, which supplies the mylohyoid muscle and the anterior belly of the digastric muscle. Understanding this nerve's pathway is essential for dentists and oral surgeons during procedures like tooth extractions and nerve blocks.
