| sebaceous glands | oil glands, most of these are attached to hair follicle |
| Does the epidermis have blood cells? | no |
| epidermis | above the skin |
| 90% of epidermal cells | Keratinocytes |
| Keratinocytes produce | Keratin, a protein that helps protect epidermis from abrasion/penatration, waterproof |
| Where are keratinocytes produced | Stratum basel of epidermis, pushed upwards by new cells, flatten and die |
| You have a completely new epidermis every | 28 days |
| What stimulates keratinocyte production | friction (callus) |
| Another name for langerhans cells | Dendritic cells |
| Where are langerhans (dendritic) cells formed? | The bone marrow |
| Where do langerhans (dendritic) cells migrate to | Basal layer of epidermis |
| Function of langerhans (dendritic) cells | ingest foreign substances and activate our immune system |
| Spider shaped cells | Melanocytes |
| What do melanocytes produce? | Melanin |
| Melanin | Pigment that determines the hair, skin, and eye color |
| We have _____ number of melanocytes | similar |
| What does melanin cover? | Keratinocytes, blocks them from UV radiation |
| Dendritic meaning | Branching |
| Melanocytes are only found in what layer of the epidermis? | Stratum basal |
| Another name for Merkel cells | tactile epithelial cells |
| Hypodermis parts | Adipose tissue, sensory nerve, motor nerve, blood vessels |
| Parts of the epidermis | Kerenocytes, keratin, langerhans (dendritic) cells, melanocytes, Merkel cells. epithelial cells |
| Merkel cells | sense light touch |

| Vellus hair | Peach fuzz found on face, arms, legs, stomach |
| Vellus meaning | Wool |
| Vellus hair becomes _____ hair in males during puberty | terminal |
| What skin layer is stratified and keratinized | the epidermis |
| What caused skin to be water resistant and prevent water loss when secreted by lamellar bodies? | Lipids |
| Our skin surface teams with _____ | bacteria |
| What slows bacterial growth on the skin? | Acid mantle |
| _____ and ______ have ingredients that kill bacteria | Sweat and sebum |
| What does sweat do that pulls heat away from our body? | Evaporate (Evaporative cooling) |
| How many liters of sweat do sweat glands secrete under normal conditions | 0.5 liters |
| What do your blood vessels in your skin do to bring hot blood to the surface of the skin to release heat | Dilate (widen) |
| Your blood vessels in your skin _____ which pulls blood vessels deep to trap heat | constrict (Skinnier) |
| What does the skin produce when exposed to UV rays | Vitamin D |
| Vitamin D helps our.... | Digestive tract absorb calcium |
| Vitamin D deficiency causes | Rickets, weak bones |
| What does sweat contain? | Salt, water, small amounts of urea (waste) |
| Sweat glands are distributed over the entire skin surface except | nipples and parts of genitals |
| Up to ____ sudoriferous glands per person | 3 million |
| Contract of sudoriferous glands force what out of the skins surface | sweat |
| two types of sweat glands | Eccrine and Apocrine |
| Eccrine glands are more what then apocrine sweat glands | numorous |
| Where are eccrine glands abundant? | Palms, soles of feet, forehead |
| Eccrine glands secrete 99% | water, but also some salt and traces of waste |
| Eccrine sweat prevents | overheating |
| How many apocrine glands do you have | approximately 2,000 |
| Where are the only places that apocrine glands are found in | Axillary and genital regions |
| Are apocrine glands smaller or larger than eccrine glands | larger |
| The sweat that apocrine glands secrete is | water, some salt, traces of waste, and fat |
| Due to the fat, apocrine sweat is | milkey and viscous |
| Apocirne sweat is oderless but bacteria on the skin feed on it and create | body oder |
| apocrine sweat glands begin functioning at | puberty |
| Do apocrine glands play a huge rule in maintaining body temprature | No |
| Two types of modified apocrine sweat glands | cerominous glands, mammary glands |
| Cerominous glands (part of apocrine) | produce earwax (cerumen) |
| Mammary glands (part of apocrine) | produce milk |
| Nail Matrix | thickened proximal portion of nail bed, responsible for nail growth |
| Eponychium (nail) | Known as cuticle, layer of clear skin along the bottom of a fingernail/toenail |
| Nail plate | also known as nail body, the actual fingernail made of keratin |
| Free edge | Nail tip, free part of nail plate, distal |
| Nail fold | Skin folds over the proximal and lateral borders of the nail |
| Nail root | proximal part of nail plate, embedded in the skin |
