NERVUS MAXILLARIS Meaning and
Definition
-
Nervus maxillaris, commonly known as the maxillary nerve, is a major branch of the trigeminal nerve (cranial nerve V) that carries sensory information from the maxillary region of the face. It is the second division of the trigeminal nerve and exits the skull through the foramen rotundum.
The maxillary nerve supplies sensation to various structures including the skin of the middle of the face, such as the cheeks, upper lip, and sides of the nose. It also innervates the upper teeth, gums, and the mucous membranes of the nasal cavity and palate. Additionally, the nerve provides sensory input to the maxillary sinus and parts of the meninges.
The nervus maxillaris delivers signals from these areas to the trigeminal ganglion, a sensory ganglion located within the cranial cavity. From the ganglion, nerve fibers transmit the sensory information to the brainstem nuclei, specifically the spinal trigeminal nucleus, where the signals are processed and interpreted.
Due to its extensive distribution, the maxillary nerve is important for providing general sensation to the maxillary region, assisting in functions such as touch, pain, and temperature perception. It also plays a vital role in reflexes, as stimulation of the maxillary nerve can trigger protective reflexes like sneezing or blinking.
