|
WHAT INTRACELLULAR COMPONENTS ARE STAINED BY NISSL STAINS
|
NUCLEI OF ALL CELLS AND NISSL BODIES (CLUMPS OF MATERIAL SURROUNDING THE NUCLEI OF NEURON
|
|
|
WHAT INTRACELLULAR COMPONENTS ARE STAINED BY GOLGI STAINS
|
NEURONAL CELL BODY. STAIN SHOWED NEURONS HAVE 2 DISTINGUISHABLE PARTS (A CENTRAL REGION AND NUMEROUS THIN TUBES THAT RADIATE AWAY FROM THE CENTRAL REGION. (SOMA + AXONS AND DENTRITES)
