What muscles does the maxillary nerve innervate?
In sum, the maxillary nerve innervates the skin of the lower eyelid, the prominence of the cheek, the alar part of the nose, part of the temple, and the upper lip (Figures 2.2 and 2.3).
What happens if the maxillary nerve is damaged?
As a branch of the trigeminal nerve, the maxillary nerve is often implicated in trigeminal neuralgia, a rare condition characterized by severe pain in the face and jaw. 1 In addition, lesions of this nerve can cause intense hot and cold sensations in the teeth.
Where does the maxillary nerve pass through?
It begins at the middle of the trigeminal ganglion as a flattened plexiform band then it passes through the lateral wall of the cavernous sinus. It leaves the skull through the foramen rotundum, where it becomes more cylindrical in form, and firmer in texture.
What does the maxillary nerve control?
Maxillary: This nerve branch is responsible for sensations in the middle part of your face. Maxillary refers to the upper jaw. The maxillary nerves extend to your cheeks, nose, lower eyelids and upper lip and gums.
What does the mandibular nerve innervate?
These nerve fibers innervate structures of the lower jaw and face, such as the tongue, lower lip, and chin. The mandibular nerve also innervates the muscles of mastication.
What does the mandibular nerve supply?
In general, the mandibular nerve supplies the lower face for sensation over the mandible, including the attached teeth, the TMJ and the mucous membrane of the mouth as well as the anterior two-thirds of the tongue (the posterior one third is supplied by the glossopharyngeal nerve).
How do you treat mandibular nerve damage?
Treatment of problems relating to the mandibular nerve depends largely on the nature of the damage and the symptoms it causes. Treatment may include anti-inflammatories, such as steroids or ibuprofen, and possibly surgical repair. Several drugs can be used to treat trigeminal neuralgia, Tegretol (carbamazepine)
How do you test for maxillary nerves?
5th Cranial nerve For the 5th (trigeminal) nerve, the 3 sensory divisions (ophthalmic, maxillary, mandibular) are evaluated by using a pinprick to test facial sensation and by brushing a wisp of cotton against the lower or lateral cornea to evaluate the corneal reflex.
What does the mandibular nerve affect?
Mandibular Nerve Function These include the masseter, the lateral and medial pterygoids, and the temporalis muscle. This nerve also carries sensory fibers from the lower lip, lower teeth, gums, chin, and jaw, which allow you to feel pain, touch, and temperature changes in and around the mouth.
What muscles does the mandibular nerve supply?
It also supplies the muscles of mastication which are the medial and lateral pterygoids, temporalis, and masseter. It also supplies some smaller muscles namely the tensor veli tympani, tensor veli palatini, mylohyoid, and the anterior belly of digastric.
