Components

(generated)

Component items:

• Lamina VII (SC.IZ.L7)
  • Central Cervical Nucleus (LLC.SC.IZ.CCV): Coordinate voluntary movements, maintain balance, and learn motor skills
  • Centrobasalis Nucleus (LPC.SC.IZ.CBS): Unconscious proprioception to CR
  • Intermediomedial Nucleus (LPC.SC.IZ.IMM): Visceral sensory
  • Intermediolateral Column (AVA.SC.IZ.IMLC)
    • Intermediolateral Nucleus (LAC.SC.IZ.IML): Mediate entire sympathetic innervation of body
    • Ciliospinal Center (LAC.SC.IZ.CSC): Control of iris dilator muscle
    • Sacral Parasympathetic Nucleus (LAC.SC.IZ.SPS): parasympathetic impulses pass via postganglionic fibers to the urinary bladder, erectile tissues, and the smooth muscles and glands in the colon and rectum
