What is the lower alveolar nerve?

The lower alveolar nerve (IAN), also called the lower dental nerve (idn), is a nerve that passes the lower jaw or jaw. The lower premolar, dog and incisors, as well as chin, gums and lower lip, branches. The term inernate refers to the supply of nerves to the body part. The mandibular nerve is the third, the bottleness of the trigeminal or skull nerve, which controls most of the feeling and movement of the face. When the lower alveolar nerve passes through the jaws, it sends a branch called the mental nerve across the mental foramen, another hole in the jaw to innervate premolar teeth, chin and lower lip. The lower alveolar nerve then continues around this branch point to add nerves to the lower canines and incisors.

The nerve consists of axons, dendrites, Schwann cells and other supporting structures that are associated and cloak into a line -like structure. Nerves give signals between the nervous system and other organs so that the body can feel and respond to stimuli such as pressure or temperature. They are dividedMediced into two groups according to the function: sensory or afferent, group and engine or epferent, group.

nerves can be afferent, eperential or mixture of these two. Effects the nerves take the impulses from the nervous system and send motor signals to the body organs, for example to communicate the muscles to move. Afferent nerves take pulses towards the central nervous system and transmit sensory signals such as pressure receptor pain. The lower alveolar nerve is an afferent nerve that gives the feeling of teeth, gums, chin and lower lip. For this reason, dentists often anesthetize this nerve to dental procedures that could cause pain and require the anesthesia of the front of the lower jaw.

Blocking the lower alveolar nerve means injection of local anesthesia to prevent pain in a particular area. The patient remains conscious during the procedure. The exact location of the injection differs in dependentOutstanding on the anesthesia site. A dentist may injection anesthesia in mandibular foramen, which is located in Ramus, where the back of the lower jaw forms a right angle. This blocks the feeling in the lower premolars, spikes and cutters and mental nerve serving chin and lip. In addition to the lower alveolar nerve, anesthesia injected near the mandibular foramen will also block lingual nerve and give the feeling of tongue.

Injection of anesthesia over mandibular foramen on the ascending ramus dulls a larger area. In addition to the lower alveolar nerve, this block affects the buccal nerve, which gives the sensacina face and the second and third molar. This is called the Gow-Gates block or the V3 block.
