**USE OF COMPOUND MICROSCOPE AND MICROSCOPIC SLIDES:**

* compound microscope is used to observe small objects at high magnification
* Typical magnification used in biological microscopes are 40x, 100x, 400x and 1000x.

CLASSIFICATION OF TISSUES:

EPITHELIAL TISSUE 

* covers exposed surfaces & lines internal passageways & forms glands
* Cells have apical (free) surface & basal surface
* cells fit together to form membranes (sheets) & supported by connective tissue
* Cells are avascular & have a basal membrane
* Classification is based on 1) number or arrangement of layers & 2) cell shape.

CLASSIFICATION OF TISSUES:

epithelial tissue

simple epithelium

consists of a __*single*__ layer of cells attached to a basement membrane.

CLASSIFICATION OF TISSUES:

epithelial tissue

stratified epithelium

consist of __*several*__ layers of cells attached to a basement membrane

CLASSIFICATION OF TISSUES:

epithelial tissue

pseudostratified epithelia

appear multilayered but all the cells are attached to the same basement membrane.
