Components

(generated)

Component items:

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