The mylohyoid nerve (or nerve to mylohyoid) is a mixed nerve of the head. It is a branch of the inferior alveolar nerve . It provides motor innervation the mylohyoid muscle , and the anterior belly of the digastric muscle .
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 ...
The risk of nerve injury in relation to mandibular dental implants is not known but it is a recognised risk requiring the patient to be warned. [10] If an injury occurs urgent treatment is required. The risk nerve injury in relation deep dental injections has a risk of injury in approximately 1:14,000 with 25% of these remaining persistent.
Eagle syndrome (also termed stylohyoid syndrome, [1] styloid syndrome, [2] stylalgia, [3] styloid-stylohyoid syndrome, [2] or styloid–carotid artery syndrome) [4] is an uncommon condition commonly characterized but not limited to sudden, sharp nerve-like pain in the jaw bone and joint, back of the throat, and base of the tongue, triggered by swallowing, moving the jaw, or turning the neck.

The major tissues affected are nerves and muscles, where irreversible damage starts to occur after 4–6 hours of cessation of blood supply. [4] Skeletal muscle, the major tissue affected, is still relatively resistant to infarction compared to the heart and brain because its ability to rely on anaerobic metabolism by glycogen stored in the cells may supply the muscle tissue long enough for ...
Multiple sclerosis (MS) is a chronic disease of the nervous system that can lead to muscle weakness, vision loss, and paralysis. It occurs when the immune system attacks the myelin sheath that ...
Different toxins may cause different types of injuries, and many will cause injury to specific organs. [20] Toxins in gases, dusts, aerosols, and smoke can be inhaled, potentially causing respiratory failure. Respiratory toxins can be released by structural fires, industrial accidents, domestic mishaps, or through chemical weapons.
Neurapraxia is the least severe form of nerve injury, with complete recovery. In this case, the axon remains intact, but there is myelin damage causing an interruption in conduction of the impulse down the nerve fiber. Most commonly, this involves compression of the nerve or disruption to the blood supply . There is a temporary loss of function ...
