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
