The maxillary nerve V2 carries sensory information from the lower eyelid and cheek, the nares and upper lip, the upper teeth and gums, the nasal mucosa, the palate and roof of the pharynx, the maxillary, ethmoid and sphenoid sinuses and parts of the meninges.

The mandibular nerve V3 carries sensory information from the lower lip, the lower teeth and gums, the chin and jaw except the angle of the jaw, which is supplied by C2-C3parts of the external ear and parts of the nervus trigeminus adalah.

The mandibular nerve carries touch-position and pain-temperature sensations from the mouth. Although it does not carry taste sensation nervus trigeminus adalah chorda tympani is responsible for tasteone of its branches—the lingual nerve —carries sensation from the tongue.

The sensory function of the trigeminal nerve is to provide tactile, proprioceptiveand nociceptive afference to the face and mouth. Its motor function activates the muscles of masticationthe tensor tympanitensor veli palatinimylohyoid and the anterior belly of the digastric.

The trigeminal nerve carries general nervus trigeminus adalah afferent fibers GSAwhich innervate the skin of the face via ophthalmic V1maxillary V2 and mandibular V3 divisions.

The trigeminal nerve also carries special visceral efferent SVE axonswhich innervate the muscles of mastication via the mandibular V3 division.

Muscles of mastication[ edit ] The motor component of the mandibular division V3 nervus trigeminus adalah the trigeminal nerve controls the movement of eight muscles, including the four muscles of mastication: The other four muscles are the tensor veli palatinithe mylohyoidthe anterior belly of the digastric and the tensor tympani.

A unilateral central lesion for example, a strokeno matter how large, is unlikely to produce an observable deficit.


Injury nervus trigeminus adalah a peripheral nerve can cause paralysis of muscles on one side of the jaw, with the jaw deviating towards the paralyzed side when it opens.

This direction of the mandible is due to the action of the functioning pterygoids on the opposite side.

Somatosensory system The two basic types of sensation are touch-position and pain-temperature. Touch-position input comes to attention immediately, but pain-temperature input reaches the level of consciousness after a delay; when a person steps on a pin, the awareness of stepping on something is immediate but the pain associated with it is delayed.

Touch-position information is generally carried by myelinated fast-conducting nerve fibers, and pain-temperature information by unmyelinated slow-conducting fibers. Sensation in this context refers to the conscious perception of touch-position and pain-temperature information, rather than the special senses smell, sight, taste, hearing and balance processed by different cranial nerves and sent to the cerebral cortex through different pathways.

The perception of magnetic fields, electrical fields, low-frequency vibrations and infrared radiation by some nonhuman vertebrates is processed by their equivalent of the fifth cranial nerve.

Touch in this context refers to nervus trigeminus adalah perception of detailed, localized tactile information, such as two-point discrimination the difference between touching one point and two closely spaced points nervus trigeminus adalah the difference between coarse, medium or fine sandpaper.

People without touch-position perception can feel the surface of their bodies and perceive touch in a broad sense, but they lack perceptual nervus trigeminus adalah. Position, in this context, refers to conscious proprioception. Proprioceptors muscle spindle and Golgi tendon organs provide information about joint position and muscle movement.

Although much of this information is processed at an unconscious level primarily by the cerebellum and the vestibular nucleisome is available at a nervus trigeminus adalah level.

Touch-position and pain-temperature sensations are processed by different pathways in the central nervous system.


This hard-wired distinction is maintained up to the cerebral cortex. Within the cerebral cortex, sensations are linked with other cortical areas. Sensory pathways[ edit ] Sensory pathways from the periphery to the cortex are separate nervus trigeminus adalah touch-position and pain-temperature sensations.

All sensory information is sent to specific nuclei in the thalamus.

Thalamic nuclei, in turn, send information to specific areas in the cerebral nervus trigeminus adalah. Each pathway consists of three bundles of nerve fibers connected in series: The nervus trigeminus adalah neurons in each pathway decussate cross the spinal cord or brainstembecause the spinal cord develops in segments.

Decussated fibers later reach and connect these segments with the higher centers. The optic chiasm is the primary cause of decussation; nasal fibers of the optic nerve cross so each cerebral hemisphere receives contralateral—opposite—vision to keep the interneuronal connections responsible for processing information short.
