Where does epithelium comes from?

Back 2

Where does epithelium comes from?
anytime epithelium is destroyed or rupture it doesn’t completely disappear, it leaves clumps of epithelium cells called epithelium rests

Front 5

Explain the brith of a cyst:

Back 5

Something may come along sometime throughout life usually inflammation that will stimulate one the epithelium rest and will start to enlarge and grow->as clumps of epithelium rest or cells get larger the cells in the middle get further and further away from their blood supply->so they start to die and break down->then you get the birth of a cyst and-> as the cells in the center continue to break down it attracts more fluid from the outside because it’s a hypertonic solution like concentrated salt water as it attracts more fluid cyst gets larger
