What is simple squamous? and what does this membrane secrete? What does it have underneath it? What are two examples where simple cuboidal is found? Are they secretory? What is an example of simple columnar? What is an example of stratified squamous? What can the upper cells do?

–
Epithelial tissue - forms unicellular glands (one cell glands) Mucous secreting cells: 1. Contain apical mucous g_____ 2. Where is the nucleus? 3. What shape are they?
-
