DEFINITION OF COMPOUND EPITHELIUM
3
A multilayered arrangement of cells, Only basal cells resting on the basement
membrane. Apical cells vary in shape and size. A group of cells arranged in many layers, with
out having intercellular spaces and material like fibers and ground substance.
It is also called as stratified epithelium.

STRATIFIED COLUMNAR EPITHELIUM
12
1. Stratified columnar epithelium
is very rare2.It is found in the largest duct of salivary glands (Parotid, Submandibular)

The transitional Epithelium/UROTHELIUM
15
1.The transitional epithelium is a special type of stratified epithelium.
2. It is found in urinary passages.
3.When the bladder is full, the apical cells stretches and become squamous.
4.In the relaxed bladder, the apical cells are balloon like/ umbrella like/dome like.

SPECIALISED EPITHELIUM
20
1. Olfactory epithelium is specialized
2. The olfactory cells are modified bipolar neuronal cells.
There is no regeneration in these cells, no mitosis
They carry yellow pigment.
Found in the roof and on nasal turbinate.3. Taste buds also have specialized
epithelium.4. The hair cells of inner ear are also modified epithelium SC= SUSTENTACULAR CELL,OC=OLFACTORY CELL,BC=BASAL CELL.

Applied anatomy
21
1.All glands arise from epithelium.
2.The tumor arising from epithelium is called as cancer.
3.Kartagener’s syndrome is due to non action of cilia resulting in Bronchectesis, dextrocarida and situs in versus.
