Tissues

groups of cells and the extra-cellular substances surrounding them

Histology

it is the microscopic study of tissue structure

epithelium

it forms the layers that cover the surfaces and line the hollow organs of our body

epithelium

is especially important in hollow organs with openings to the outside environment, because it protects against foreign materials entering the body

1. epithelium tissue

2. connective tissue

3. muscle tissue

4. nervous tissue

4 primary types of tissues

1. mostly composed of cells

2. covers body surfaces

3. has an exposed surface

4. attaches at the basal surface

5. has specialized cell connections and matrix attachments

6. is vascular

7. is capable of regeneration

Free surface

the surface that is exposed is called ____

apical surface

free surface is also called ___

basal surface

the surface of the cells that is anchored in place is called ___

basement membrane

this material is called the ____ and is composed of specialized extracellular material secreted by the epithelial cells

lateral surface

between the epithelial cells is the ____, where the epithelial cells are attached to each other.
