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
