Q

What are the layers of the outermost superficial region is waterproof and why?

A

Stratum granulosum and it is water proof due to housing the glycolipids from lamellated granules and keratohyaline granules.

pustule
Pus filled sac | Pimple
58
Cyst
Fluid filled mass deep
59

(Spider angioma) Tiny red blood vessel lesion formed by dialation of a group of blood vessels radiating from a central arteriole Most common on face neck or chest
60
Scale
Think flake of exfolative epidermis | Ex dandruff
61
Keloid
Abnorm growth of scartissue thick and irrgecular
62
Lichenification
Leathering and thickening | ex: in atopic dermatitis
63

Scratch mark
64
Macule
discolored flat spot up to 1 cm | Ex freckle
65
Fissure
Linear crack in the skin
66
Erosion
Gnawed away Loss of superficial epidermis leaving an area of moisture but no bleeding Ex: after vesicle rupture
67
Ulcer
Open soar on the skin Or mucus membrane Can bleed and scar; sometimes accompanied by infection Ex: decubitis ulcer
68
Petechiae
Reddish brown spot, small purpura | Hemmoragic spots, indicate bleeding
69
Purpura
Purple spot, from hemorrhages into the skin
70
