There are three histologic specimens of cartilaginous tissue. Two of them are

stained with hematoxylin-eosin, and one histologic specimen is stained with

orcein. What fibres and in what type of cartilaginous tissue can be determined

by such dyes? What functional properties of the cartilaginous tissue do they

cause?
