First off, I'm confused as to why this is in the "Human Anatomy" catagory?
Anyway, the spinal cord of a squirrel monkey is similar to that of any other primate including humans. I recommend Britannica for a grossly in depth explanation of the exact structure of a squirrel monkey's spinal cord.
Yes it is a mammal.
Spinal cord......
brain and spinal cord
There is no joint between brain and spinal cord. The spinal cord is a mass of neurones that is situated in the backbone which feeds in to the brain via neurones.
vertebral column
No. It is a structure of nervous tissue and cells.
The neural tube develops into the vertebrate spinal cord. It forms early in embryonic development from a flat sheet of neural ectoderm that rolls into a tube, eventually differentiating into the brain and spinal cord.
Tethered Spinal Cord is a condition where the spinal cord is attached to the spinal column and that causes the cord to become stretched.
medulla oblanga
Posterior root
medulla oblongata from the spinal cord
human, monkey...
