The mylohyoid nerve is a branch of the inferior alveolar nerve, which itself is a part of the mandibular nerve. This nerve primarily supplies the mylohyoid muscle and the anterior belly of the digastric muscle, both of which are important for movements related to swallowing and speaking. In addition to motor functions, the mylohyoid nerve also carries sensory fibers that provide sensation to the skin of the lower jaw and the floor of the mouth. Understanding the mylohyoid nerve is essential for dental procedures and surgeries in the lower jaw area, as it can influence pain management and recovery.
