The spinal cord is a tube like structure protected in the vertebral column. It does not show any cranial nerve nuclei but very important tracts pass through it.
You will be surprised to learn that the spinal cord is less than a finger in thickness. Yet it is able to carry out it's functions perfectly. The spinal cord, if injured, can have serious consequences. An example of such serious consequences is sciatica.
The spinal cord at different levels shows such considerable differences that even looking at an H&E ( hematoxylin and eosin ) stained slide of the spinal cord without the aid of a microscope, seeing the shape of the inner grey matter and the size of the oval, one can easily judge whether the section was taken at the cervical, thoracic, lumbar or sacral level.
I would like to apologise again for the short forms used, but their long forms are -
HypoS=Hypothalamo Spinal
PSC=Posterior Spino Cerebellar
ASC=Anterior Spino Cerebellar
LST=Lateral Spino Thalamic
SO=Spino Olivary
AST=Ascending Spino Thalamic
LReS=Lateral Reticulo Spinal
MReS=Medial Reticulo Spinal
LCS=Lateral Cortico Spinal
RS= Reticulo Spinal
OS=Olivio Spinal
VS=Vestibulo Spinal
TS=Tecto Spinal
ACS=Anterior Cortico Spinal
