Function
The epidermis provides this
Protection
Waterproof
UV protection
Another name for the cutaneous membrane
The skin
skin color and UV protection are the responsibility of this
melanin
T or F. the skin cells that are the most superficial are dead essentially
True
Skin detects stimuli. Stimuli is processed by the NS.
The dermis has several items that live there. List 1 function of any two structures here.
thermoregulation
reduce friction
fight bacteria
sensory perception
This structure is made of sheets of hardened keratinocytes in order to provide protection to a distal end
nails
Detection of stimuli includes what types of sensations
pain, pressure, touch, temperature
This vitamin is produced when the sun is exposed to sunlight for a period of time
Vitamin D
Can you connect the IS to the MS?
Arrector pili muscles make hair stand up to help trap the heat
Provide some protection to the muscles that lie under
Who can tell me what collagen does?
Toughness
Hydration
This structure contains less dense levels of keratin which allows for flexibility. It is also elongated, not as tightly packed and has differing levels of melanin.
Hair
Name 3 structures located in the dermis
oil glands
sweat glands
nerve stuff
blood vessels
hair
How many feet are in a yard?

Besides making your beautiful or semi handsome, what does hair do? Or is is hairdo?
Protects against heat loss and UV radiation.
Some minor protection against ouchies
These types of cells protect, cover, and line
Epithelial cells
Eslatin does this
Gives skin elasticity
T or F. Keratinization is cells become harder, flatter and tightly packed to form a protective barrier
T
Know why this is important
There are two ways the the skin regulates heat. Describe 1 of them
Heat is transported to the skin's surface via the blood stream. Sweat is produce in the dermis, and transferred to the skin. Heat from the skin is transferred to the sweat. Sweat evaporates.
Blood vessels constrict. Heat is kept away from the surface, warming deeper structures. Arrector pili muscles stand.
These structures are responsible for lubricating the skin against friction as well as having antibacterial assistance

(I bet someone says Titanic)
This is the muscle that gives us goose bumps, helping hair to trap heat
