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

  • Top-down path to region: Hindbrain Myelencephalon -> Myelencephalic Sensory Nuclei (HL.SN) -> Trigeminal Sensory Nuclei (HL.TGS) -> Spinal Trigeminal Nucleus (LPC.HL.TGS.STR) (see Mind Maps)
  • Type: nucleus
  • Brain area: Lower Brain - Peripheral Control Area
  • Role: sensory.nucleus
  • Function: Discriminative sensation and light touch of face, conscious proprioception
  • Notes to function: Pontine Nuclei, part of cranial nerve nuclei, ear, similar to SG of spinal cord
