Q
Epidermis

Constist of several layers of stratified squamous epithelium.
- cells produced in basal layer
- cells pushed up flattened, fill up w/ keratin & die
- layers of packed dead cells accumulate in the outermost layer, where they are sloughed off.

Injury to the body tissue caused by heat, chemical, electric, radiation, or gases
39
First degree burn
Burn involving only epidermis
•characterized by erythema (redness) &; hyperesthesia (excessive sensation)
40
