stratified squamous
around mouth and esophagus can be reached from an opening on the exterior (mouth, nose,ears,uretha,etc.) often adapted for absorption and secretion |
|
|

|
damaged epidermis and upper dermis and the skin blisters
A blistering sunburn is an example |
|
|
|

|
What are the two ways that cancer is classified?
|
Benign and malignant
|
|
|
|
True or false skin cancer is the most common type of cancer
|
True
|
|
|
|
Basale Cell Carcinoma
|
least malignant
most common cells of stratum Basale are altered so that they cannot form keratin and longer honor the boundary between epidermis and dermis sun exposure |
|
|
|
Squamous Cell Carcinoma
|
arises from the sounds of the stratum spinosum
Gradually forms a shallow ulcer with firm raised border Grows rapidly Usually found around the scalp ears dorsum of hands and lower lip |
|
|
|
Malignant melanoma
|
Cancer of melanocytes
Only about 5 percent of skin cancer Often deadly Appear spontaneously Some developed from pigmented moles Spreading brown to black patch. Grows quickly 50 percent survival rate |
