TISSUE REVIEW
• The following slides are from your text or other sources.
This will allow you to study tissues at home.
• You are also responsible for tissue slides that we view with
the microscope in class.
• Always study the Histology Atlas available online from the
textbook’s website – PAL , or your PAL CD
• know:
– name of the tissue
– cells and other structures
– the function of the tissue
– where it is found

procedure to identify epithelial tissues
• Does the tissue contact an opening?
• Is it made entirely of cells?
• if it’s epithelial :
– # layers
– what is the shape of cells
– other structures - cilia, microvilli, basement membrane
– what function matches this structure?
• if it’s not epithelial :
– see connective tissue procedure
– muscle, nerve
•

If it’s all cells, is it epithelial or connective tissue ?

note: the blood vessel and blood are two different tissues. Even though
the lumen of a blood vessel is filled with blood, the cells of the blood
vessel are said to be contacting an opening, and thus, are epithelia.

simple squamous
you’re looking at a thin
ring of simple squamous
cells that make up the
wall of an alveolus in the
lung.
You see many, flat nuclei

Glands are long, coiled openings
lined with cuboidal cells.
So, when we slice through
the tissue, we get many
circular arrangements of
cuboidal cells
