Myelencephalic Sensory Nuclei

@@Home -> BiologicalLifeResearch -> BrainCenterHL_SN

This page covers biological details of component group Myelencephalic Sensory Nuclei. Component group is part of aHuman target integrated biological model.

  • Top-down path to center: Hindbrain Myelencephalon -> Myelencephalic Sensory Nuclei (HL.SN) (see Mind Maps)
  • Function:




Component items:

  • Cochlear Nucleus (LPC.HL.COCH): Divergence in representation of auditory information
  • Trigeminal Sensory Nuclei (HL.TGS)
  • Spinal Sensory Nuclei (HL.SS)
    • Dorsal Column Nuclei (HL.SS.DCN)
      • Cuneate Nucleus (LPC.HL.CU): Carry fine touch and proprioceptive information from upper body
      • Gracile Nucleus (LPC.HL.GR): Carry epicritic, kinesthetic, and conscious proprioceptive information from lower body
    • Accessory Cuneate Nucleus (LPC.HL.ACU): receives input from cervical spinal nerves and transmits that information to cerebellum
    • Inferior Olivary Nucleus (LLC.HL.IO): Proprioception Relay from Spinal Cord to Cerebellum
  • Solitary Nucleus (LPC.HL.SOL): Carry taste buds, thoracic and abdominal viscera
  • Arcuate Nucleus of Medulla (LLC.HL.ARC): Relay cardiorepriratory proprioception to cerebellum
