NERVOUS TISSUE

The cell bodies of two neurons (A) are well defined. The outline of the nuclei (N) inside the cell bodies can be seen faintly, but it is very easy to spot their nucleoli (n): the dark spots inside the nuclei. The thicker neuronal ramifications (B) can also be seen clearly: these are the brown lines interspersed in the yellow background. In spite of what it seems, the yellow background is not an extracellular substance separating neurons. It is jam-packed with cells: glial cells and smaller ramifications of the neurons.
