What does epithelial tissue do?
Cover internal and external surfaces
What is the general appearance of epithelial tissue?
Tightly packed
Few intercellular air spaces
Little material between cells
What is simple epithelial tissue?
Single cellular layer
Rests on a basal membrane
What is stratified epithelial tissue?
Multiple layers of cells
Where can squamous epithelium be found?
In the internal walls of cavities
Blood vessels, heart, alveoli, mouth oesophagus
What is endothelium?
The squamous epithelium that lines the inside of blood vessels
What is endocardium?
The squamous epithelium that lines the heart
What does squamous epithelium look like?
Single layer Thin Flat Tightly packed Arranged Ina mosaic pattern Nucleus horizontally flat and oval shaped
What does squamous epithelium do?
Prevents friction
Is permeable to gases and liquids
Protects underlying tissues
Where can cuboidal epithelium be found?
Lines glands that secrete or absorb Thyroid gland Sweat glands Salivary glands Renal tubules Embryonic epithelium
What is embryonic epithelium?
Gives rise to ova
And sperm
What does cuboidal epithelium look like?
Cube shaped
Nuclei are round and occur in the centre of the cell
What is the function of cuboidal epithelium?
Secretion
Absorption
What is secretion?
Release of useful substances
