CONNECTIVE TISSUES. 21 
Describe glandular epithelium. 
Glandular epithelial cells in form are columnar, cubical, polyhedral, 
or spheroidal in shape, and are usually set around a tubular or saccular 
cavity upon a basement membrane. 
Describe ciliated epithelium. 
These varieties are usually cylindrical in shape, and on their free 
borders bear little hair-like processes, which in life havea lashing or 
vibrating motion. 
What is the shape and arrangement of cells in stratified epithelium ? 
The deepest layer is columnar and the superficial layer scaly. In the 
intermediate layer of cells next the deepest layer, the cells are round, 
but gradually become flattened as we approach the superficial layer. 
The cells of this last layer have lost their nuclei and become horny in 
structure. 
Where is the best example of transitional epithelium found ? 
In the lining wall of the bladder. 
What are the characteristics of this form of epithelial tissue ? 
The superficial layer of cells is either,flattened or cubical in shape, 
the cells being smooth on their free surface and pitted on their opposite 
side. In the next layer the cells are pear shaped, the large end fitting 
into the depressions on the under surfaces of the superficial cells, and 
the small end set upon the subjacent connective tissue. Filling these 
spaces between these tapering cells is a third layer of irregular-shaved 
cells. 
CONNECTIVE TISSUES. 
Of what elements is connective tissue composed ? 
Fibres, intercellular substance, cells, vessels, and nerves. 
Give the principal varieties of the connective tissues ? 
, Fibrous, Adipose, Cartilage, 
Embryonal, 5 Reticular, Bone, 
ae Mucous or mucoid, Lymphoid, Elements of blood and lymph. 
Into what subdivisions are the fibrous connective tissues divided? 
Areolar, white fibrous, and yellow elastic tissue. 
What are the physical characteristics of white fibrous tissue ? 
It is white with a shiny or pearly lustre. 
It is exceedingly tough but pliant.
