The largest organ and its layers…
The skin
Outer layer: epidermis, contains inner basal layer and horny cell layer
Middle layer: dermis, contains collagen and connective tissue
Inner layer: subcutaneous layer, contains adipose tissue made up of lobules of fat cells
Structures in the epidermal layer..
Hair: vellus(fine) and terminal(dark, thick, on head)
Sebaceous glands: produce sebum (secreted in hair follicles) decrease in their function can cause dry skin
Sweat glands
–Eccrine glands: clear sweat
–Apocrine glands: milky in the axillary area
Nails: hard plates of keratin
What are the functions of the skin
Protect against infection
Perception: nerves, feeling, sensing
Regulate temperature: by sweating and also from adipose tissues in subQ layer
Identification from others
Communication: turn certain colors with certain feelings
Repair lesions
Absorbs vitamin D
Skin conditions specific to black patients
Keloids
Pigmentary disorders
Pseudofolliculitis
Melasma
Variables that could influence skin color
Emotional states Temperature Smoking cigarettes Prolonged elevation of extremities Extremities in a dependent position Prolonged inactivity
Where should you assess the skin during an examination
Inspect the body as a whole
Look at skin tone & color
Look between places: breasts abdominal folds
Always inspect feet, toenails, in between toes, heels, and butt

What are primary lesions?
They develop suddenly on unaltered skin
What are secondary lesions?
They occur after the primary lesion, from itching/scratching, infection, etc.
