Mesencephalic Trigeminal Nucleus

@@Home -> BiologicalLifeResearch -> BrainAreaLPC -> BrainRegionLPC_MM_MSTR

This page covers biological details of component Mesencephalic Trigeminal Nucleus. Region is part of aHuman target integrated biological model.

• *Top-down path to region*: Midbrain Mesencephalon -> Perhipheral Nuclei of Midbrain Mesencephalon (MM.PER) -> Mesencephalic Trigeminal Nucleus (LPC.MM.MSTR) (see Mind Maps)
• *Type*: sensory ganglion
• *Brain area*: Lower Brain - Peripheral Control Area
• *Role*: sensory
• *Function*: unconscious proprioception from muscle spindles; facial somatic sensations from muscles of mastication, monosynaptic masticatory reflex
• *Notes to structure*: sensory neurons of masticatory muscles, the teeth, the mandibular joint, the mandible, the maxilla and the intraocular muscles; most to motor trigeminal, few - to principal trigeminal
• *Notes to function*: Lower, mandibular - ganglion; mandible and maxilla - tooth pulp, surrounding gingiva, periodontal membrane and a vast portion of the oral mucosa
