Question
11. COMPACT BONE:
another tune
Bone is considered a (circle one: fluid, loose, dense, semisolid, or solid) connective tissue. Unlike other connective
tissues, bone has a special mineral in its ECM called calcium phosphate.
Draw what you see. Find one osteon and label the central
canal and lacunae. Note: "ground" bone is a very thin slice of
bone that was not stained, just ground very thin.
Part C. SKIN:

EPIDERMIS:
Osteon-
Central canal
Remember that epithelial tissues are more darkly stained because they have more cells? This dark colored ribbon
and the flaking dead layers above it is the epithelium of the epidermis. The thicker, lighter colored areas are the
connective tissues of the dermis and hypodermis.

Osteocyte in lacuna
The epidermis is made up of 5 layers or strata but they combine to form one epithelial tissue. You should see distinct
areas of keratinized strata (1-2) and non-keratinized strata (3-5).
How can you tell from looking at the cells in the strata whether they are keratinized or non-keratinized?
What shape of cell do you see in the first living layer (3)? ______
Tissue names come from the apical layers of cells, in this case, the shape of the cells in the stratum granulosum.
Using this information, name the tissue of the epidermis:
+ 1 if mentioned keratinized
Why does the skin need this type of tissue to cover the outside of the body?
