Hints for Slide ERG 13.  

This specimen is slightly abnormal, with patches of inflammatory infiltrate scattered throughout.  Nevertheless, this specimen should still be readily recognizable, provided you are familiar with the organ it represents.

Note that this is a solid organ (as opposed to a hollow or tubular one).

Note the prominent organization into lobules of various sizes, with conspicuous connective tissue where the lobules are attached to one another.

Note the many small tubular structures scattered throughout the specimen, with larger tubules in the thicker masses of connective tissue.

  • What kinds of epithelium line these various tubules?

Note that the lobules contain several distinct types of cells.

Hints on the next page are more revealing.  Don't look until you are ready to confirm your identification.
