SLIDE 76 - SPINAL CORD-SILVERED

Certain features show more clearly here because of the blackening of nerve cell processes.  Note the gray matter butterfly with yellow anterior horn cells embedded in a meshwork of black nerve processes.  In the white matter cross-cut, axons look like dots in the middle of empty circles, where myelin has dissolved out.  Look for yellow dura, arachnoid, and pia surrounding the cord. There may be some evidence of dorsal and ventral roots.
