Spinal Cord xs

Spinal cord xs showing detail of gray and white matter

xs of nerve (100x) Fascicle xs of nerve (400x) showing detail

Very nice SEM image of nerve, showing myelinated axons in bundles (fascicles)

(above) cross section of spinal cord with detail of dorsal root, dorsal root ganglion and ventral root (right)

Cerebrum, showing cortex (gray matter) and white matter. Picture above is low power with easy visual distinction between the gray and white, on the right is a higher power with the somewhat variable layers of the cortex indicated.

Cerebellar cortex (two layers) and the arbor vitae cerebellar cortex layers arbor vitae

Optic Notice the absence nerve of photoreceptors (3 rd layer) in this area which is the optic disc.
