Question 11 - Single Best Answer

Identify the cell at the tip of the arrow:

C) lymphocyte

A lymphocyte sometimes casts a translucent "halo" around a very small and dense nucleus. There are typically only a very few number of lymphocytes migrating through the epithelium at any one time. However, by comparing the nucleus of this basal cell to its neighbors, it is apparent that the basal cell is present in relatively large numbers.
