Tissue -
A aggregate of with similar structure and
function.
Histology -
The science that studies tissues.
Epithelial Tissue –
Groups of cells that are

Protective
Absorptive
Secretory
Transport
Excretory
Closely attached to each other to form tight sheets
lacking in extracellular matrix and vascularization.
 Cells rest on basal lamina which in turn rests on
connective tissue.
 Free on one end (Apical Surface).

Connective Tissue
Perform binding, support ,transport and nutritive functions
Connective tissue has three types of fibers
Collagenous (white) Fibers –Relatively large, thick bundels.
Reticular Fibers - Minute network of very fine threads stains
well so it looks black.
Elastic (yellow) Fiber- contains elastin protein. Found in
organs and tissues that must yield to changes in shape.
Connective Tissue Matrix
Extra cellular fluid consisting of fibers, fluids, ground
substance and or inorganic compounds form the
connective tissue matrix.
Cell types seen in matrix are fibroblasts, adipose cells,
mast cells, plasma cells, macrophages and other types
of blood cells.
Ground Substance
An amorphous solution or gel around the cells and
fibers
