Palms of your hands and soles of her feet.
Calluses should never be completely removed this can lead to injury or infection. The skin is composed of the epidermidis and the dermis.
The epidermidis has no blood vessels and has many small nerve endings. It is made up of:
- The deepest & living layer. Stratum germinativum: the _______
And has a special column shaped cells that produce___. A dark skin pigment called melanin. Helps protect sensitive cells in the dermis from exposure to excess___of the sun or tanning lamps. The type of melanin produced determines our skin color. - Just above is the stratum _____.Where skin cell_____begins.
- In this layer of cells are dying as they were pushed to the surface to eventually replace other dead cells shed from the skin. Stratum ____.
- This slayer is clear and transparent under the skin surface with small sells through which light can pass. Stratum ______
- The horny layer stratum_____ is the outer layer of the epiderm is the one we see and is cared for and continually sheds cells contain significant amounts of____. A fibrous proteins component of hair and nails. Cells combine with lipids and fats produced by the skin to make it a protective Water resistant layer.
Basal layer, melanocytes, Ultraviolet energy.
Spinosome, shedding
Granulosum.
Lucidum
Corneum, keratin
Thermos is highly sensitive made of connective tissue 25 times thicker than the epidermidis with numerous blood Bessel’s length Cecils and nerves. Sweat glands oil glands and hair follicles as well as___. These are tiny involuntary muscles at the base of the hair follicles that cause goosebumps. And _____ , which are small cone shaped projections of elastic tissue the point upward into the epidermis. The dermis is made up of the ______ superficial layer and the ______ deeper layer.
Arrector pili muscles
Papillae
Papillary
reticular 
The papillary layer is directly between the epidermis and is the outer layer of the dermis. And it has dermal papillary small cone shaped elevations under the hair follicle with some loops capillaries or tactile corpuscles with nerve endings sensitive to touch and pressure also has melanocytes pigment producers.
The reticular layer is deeper supplies the skin with oxygen and nutrients and contains the following structures: \_\_\_\_\_cells \_\_\_\_\_\_oil glands \_\_\_\_\_\_ vessels \_\_\_\_ follicles \_\_\_\_\_\_pili muscles \_\_\_\_\_ endings.
Subcutaneous (adipose) tissue is under the dermis.
Fat Sweat and oil Lymph and blood Hair Arrector Nerve
Lymph resembles plasma but contains only water and other colorless substances bathe the skin cells removes toxins and other cellular waist and has immune functions that help protect the skin and body against disease.The skin cannot be nourished from outside and only from the foods that we eat.

The skin surface is covered with the following nerve fiber endings.
Motor nerve fibers that causes goosebumps. Secretory nerve fibers perspiration and sebum. And ____ fibers that react so he called touch pressure and pain and send messages to the brain found in papillary layer.
The skin gets a strength form and flexibility from two structures composed of flexible protein fibers sounds within the dermis these two structures make up 70% of the dermis and our___and___.
____ is a fibrous proteins that gives skin form and strength gifts structural support and holds all the structures together they allow skin to stretch and contracts when healthy and we can do to age a lack of moisture environmental damage like tanning and sun exposure changes and weight make it lose its tone in suppleness wrinkles and sagging result from fibers losing strength. These fibers are Interwoven with_____. A protein similar to collagen that forms elastic tissue gives flexibility and elasticity allows skin to regain its shape after stretching as we age all these fibers weekend and create sagging.
Sensory nerve fibers
Collagen
Elastin
Collagen, elastin
The skin contains two duct glands that extract materials from the blood to form new substances._____ glands (sweat glands) &______ glands (oil glands)
_____glands Excrete sweat have coil bace/secretary coil YouTube like that that opens at the surface of the skin to form a sweat pore. Most numerous at the Palms soles forhead and armpits. Regulate body temperature illuminate waste and increase activity with heat exercise emotion and drugs excretion of sweat is controlled by the___normally _____pints of liquids with salts or eliminated daily through sweat pores.
Sudoriferous

Sebaceous glands are connected to hair follicles, they have little sacs with ducts that open up to the hair follicles. The secrete Sebum a fatty secretion that lubricate the skin and preserve softness of hair made of 25%___. Which helps maintain skin in good condition and a major component of olive oil found all over the body (the face and scalp )where they are larger but not on the palms and soles. When sebum hardens and the duct becomes clogged a pore impaction or ____,a hair follicle filled with keratin and sebum is formed. Which may lead to Acne papule or pustule.

It is a myth that cosmetics absorb past the epidermidis the epidermidis prevents absorption of a very large majority of what comes in contact with the surface of the skin including cosmetics only traces of certain substances make it past this effective barrier.
Cosmetic products are designed to not penetrate pass the epidermidis making the skin a barrier to absorption.

Oh the weakening of collagen and elastin fibers as we age happens faster when the skin is frequently exposed to UV energy without protection the UV energy reaches our skin into forms UVA and UVB energy. UV is not light since not visible to human eyes so it’s called UV energy. They both influence the skin at different levels. UVA penetrate ____ than visible light and causes the skin to ____ by affecting melanocytes the cells producing melanin skin pigment. UV energy can weaken collagen and elastin fibers and cause sunburns wrinkling and sagging. _____ protects us from UV energy exposure. UVB is not as deep as UVA both are damaging to skin and eyes UVB contributes to the body synthesis of _____ and other minerals we need approximately _____minutes per day for appropriate synthesis of vitamin D.
