Wonder why you Tan?
• Basal Layer- special cells called melanocytes– Produce black
pigment called Melanin
– Sun exposure increases the rate of melanin production resulting in a tan
Different Pigmentations
• Albino- marked deficiency of pigmentation
Why do we Sweat?
• Two Important Glands– First Gland
Sudoriferous (sweat)• Produces sweat
through the pores, plentiful on palms, soles, forehead, and armpits
• Main function to cool the body, excrete waste, and moisten cells
Why do we get Acne?
• Second Gland – Sebaceous (oil)
gland– Yield an oily
secretion called sebum
– Sebum helps destroy harmful organisms on skin
– Blocked ductules lead to sebum build up and acne
Loss of hair?
• The bottom of the hair follicle is covered in papilla
• The papilla reproduces and is responsible for formation of hair
• Hair loss occurs from death of papillae
Hair Color
• Melanocytes found at the base of the hair follicle– Melanocytes
produce melanin which ranges in color from yellow to reddish brown to black
– Varying amounts of melanin produce ranging colors of hair
