The mylohyoid nerve needs to be blocked during local anaesthesia of the mandibular (lower) teeth to prevent pain during oral procedures. [ 5 ] [ 6 ] It may not be anaesthetised during a block of the inferior alveolar nerve , causing pain.
The inferior alveolar nerves supply sensation to the lower teeth, [2]: 519 and, via the mental nerve, sensation to the chin and lower lip. [citation needed] The mylohyoid nerve is a motor nerve supplying the mylohyoid and the anterior belly of the digastric. [citation needed] [contradictory]
Gravity may play a large factor in the trapping of limbs and other objects under the body at the time of death, and the subsequent observed placement of limbs after death. [6] In fatalities related to cranial or neural injury, nerve damage in the brain may inhibit the ability to release a weapon from the hand. [ 4 ]
Accessory mylohyoid muscles have been seen in some people, which have the same attachments, nerve supply, and function. [6] The mylohyoid muscle may also be split into an anterior portion and a posterior portion, with the sublingual gland occupying the space between these portions. [7] An area of herniation of the sublingual gland, blood ...
Mylohyoid: by its own nerve, a branch of the inferior alveolar (from the mandibular division of trigeminal nerve), which arises just before the parent nerve enters the mandibular foramen, pierces the sphenomandibular ligament, and runs forward on the inferior surface of the mylohyoid, supplying it and the anterior belly of the digastric.

The four classical muscles of mastication elevate the mandible (closing the jaw) and move it forward/backward and laterally, facilitating biting and chewing. Other muscles are responsible for opening the jaw, namely the geniohyoid, mylohyoid, and digastric muscles (the lateral pterygoid may play a role).
The trigeminal motor nucleus contains motor neurons that innervate muscles of the first branchial arch, namely the muscles of mastication, the tensor tympani, tensor veli palatini, mylohyoid, and anterior belly of the digastric. [1] It is situated in the upper pons, inferior to the lateral part of the floor of the fourth ventricle. [2]
