Components
(generated)
Component items:
- Lamina VII (SC.IZ.L7)
- Central Cervical Nucleus (LPC.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
