SHOW THE PRESENCE OF 3 TYPES OF NEURONS. 1 OF THEM IS NEUROSECRETORY; THE NEURONS OF THE NERVE CORD PRESENTS A TYPICAL DISPOSITION WHICH PERHAPS COORESPONDS TO A SUGGESTION/BEGINNING OF METAMERIZATION. THE STUDY WITH THE E.M. OF THIS CORD SHOWS THE EXISTANCE OF SEVERAL PROTECTIVE TISSUES. *FROM TEXT* NRV TISSUE BECAUSE DELIC \& CANNOT BE REPAIRED HAS PROTECTIVE SYSTEMS. BRAIN IS SURROUNDED BY A PERICEREBRAL SINUS \&y MUCH CONNECTIVE TISSUE. IN THE NRV. CRD. THERE ARE NOT THESE BUT THE INTERNAL LAYERS ENDOTHELIUM FUNCTION AS A KIND OF PILLOW/CUSHION FOR PROTECTION. INTERALLY THE AXONS (AMIELINICOS/WITHOUT MYELIN) ARE SEPARATED FROM EACH OTHER BY CONNECTIVE TISSUE WITH WEB OF COLLAGEN FIBERS.},
