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
• Quality: L0
• Brain area: Lower Brain - Peripheral Control Area (LPC)
• Area circuit: Sensory Face (SF)
• Role: sensory.ganglion
• Function: unconscious proprioception from muscle spindles; facial somatic sensations from muscles of mastication, monosynaptic masticatory reflex
• Comments: 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
