Document Summary
Stains: hematoxylin and eosin (h&e), periodic acid-schiff (pas), A major difference among these types of microscopy is their resolving power (resolution) ~0. 2 m or 200 nm with lm vs. 1 to 2 nm with tem. A hepatocyte has a round, euchromatic basophilic nucleus and a mainly eosinophilic cytoplasm with patches of basophilia because of the presence of rough endoplasmic reticulum. The highly euchromatic nucleus indicate that these simple-appearing cells are engaged in a multiplicity of highly complex functions: large amounts of dispersed nuclear chromatin point to the transcription of a large variety of genes. Interpretation and understanding the three-dimensional structure and organization of tissues and organs. A major challenge that confronts the student in histology is how to interpret and understand the three-dimensional structure and organization of tissues and organs by looking at apparently random two-dimensional slices of these structures.
