Module #2 OYO 2.1-2.6

2.1
This is simple columnar epithelium.

2.2
a) Simplealquamous epithelial
b) Simple cuboidal epithelial
c) Simple columnar epithelial

2.3
This tissue is moist epithelial tissue.

2.4
This is stratified transitional tissue.

2.5
It could be either of these two glands:

a)Apocrine
b)Holocrine

2.6
You could find out which one it is by watching it as it breaks off of the cell wall to see whether it breaks off completely or only partway pinches off the wall. If it breaks off completely then it is Holocrine if it only pinches off part of the cell than you know it would be Apocrine.

Another way you could check to see which kind it is if you did not see it break away ios to watch it and see whether it ruptures to let out the secretion (which would mean it is holocrine) or whether it stays together (which would mean it is Apocrine).

Or look for remnants of DNA, and if there are any that means that it is Holocrine.
