CNS organisation

  • Spinal Cord = Grey inside , white matter outside
  • Brain = Grey matter Outside ,White Matter inside

Cells Organisation of Spinal Cord

graph TD
    X{Spinal cord} ==>|outer | 1[ White Matter];
    X ==> |inner| 2[Grey matter];
    2 ==>2a[2 Horns ];
    2a ==>|Posterior| 2a1[Dorsal/Posterior Horn = cell bodies o fFasiculas Cunis,Gracialis,Spino-thalamic or inter-Neurons];
    2a ==>|Anterior| 2b1[Ventral/Anterior  Horn =  cell bodies of :octicons-arrow-down-24:er Motor Neuron];
- Grey matter in Spinal Cord = InterNeurons Cell bodies Connecting Sensory to Motor for Reflex Or Moving the Info up to Brain
