Nerve

What you see is an enlarged area of the little blue box within the upper left image.

From what specific region of the Spinal Cord is this ? The ventral horn

If you observe this histology section closely, you can see that the left side is different than the right side. Why ?

The left side is gray matter, the right side is white matter

Identify the following structures now.

A : Somatic motor nerve cell body

B : Neuroglial cell

C : Axons from motor neurons going towards the ventral root

D : Individual axon (the black little cicrcle) with myelination

Name two possible neuroglial cells visible in this section .

B could be an astrocyte or microglial cell - the white area around D is myelination from an oligodendorcyte
