Question | Answer |
Contains 4-5 layers, produces keratin, lacks blood vessels, composed of stratified squamous epithelium, serves as the outermost protective layer of the skin | Epidermis |
Thickest layer, contains special sensory receptors, contains irregular, dense connective tissue, contains muscle fibers, hair follicles, glands and many nerves and blood vessels, serves as a reservoir for water and electrolytes | Dermis |
Another name for the hypodermis, composed of loose connective tissue and insulating adipose tissue, binds the skin to underlying organs, contains the major blood vessels that supply the skin | Subcutaneous layer |
base cell layer, layer of reproducing cells, another name for stratum germinativum | stratum basale |
horny layer, most superficial layer, consists of flattened keratinized cells | stratum corneum |
granular layer, cells begin to die | stratum granulosum |
clear layer, absent in thin skin | stratum lucidum |
spiny layer, contains prickle cells | stratum spinosum |
responds to light touch | Meissner's corpuscles |
responds to heavy pressure | Pacinian corpuscles |
body of the nail | nail plate |
projects from the skin | hair shaft |
produces heavily keratinized cells | hair follicle |
portion of hair embedded in the skin | hair root |
a layer of epithelium under the nail | nail bed |
part of nail embedded in the skin | nail root |
moon-shaped white area nearest the root | lunula |
protrudes into the base of the follicle, provides the nutrients supply | hair papilla |
hair shaft is flat and ribbon-like shaped | kinky |
hair shaft is oval | wavy |
hair shaft is perfectly round | straight |
pale and fine hair | vellus |
coarser and longer hair | terminal |
white nail bed | anemia |
horizontal furrows | malnutrition/illness |
nails take on a blue cast | cyanotic condition |
loosening of the nail from the nail bed | onycholysis |
axillary and genital areas, located deep in subcutaneous layer | apocrine glands |
secrete earwax, modified apocrine glands, found in the lining of the external ear canal | ceruminous glands |
secrete perspiration/sweat, most numerous sweat glands, abundant on the palms of the hands, soles of the feet, forehead, neck and back | eccrine glands |
secrete breast milk, located in the breast | mammary glands |
secrete sebum, associated with hair follicles, secreted to help the hair stay soft, pliable and waterproof | sebaceous glands |
skin secretions and melanin | chemical barriers |
prevent the entrance and loss of substances | physical barriers |
immune system helps fight infections and attacks foreign objects | biological barriers |
heat escapes from all over the body | radiation |
heat moves to cooler objects | conduction |
air currents replace warm air with cooler air | convection |
water leaves the skin in the form of a gas | evaporation |
baldness | alopecia |
lack of melanin | albinism |
pigment-producing cells | melanocytes |
lowering of the body temperature | hypothermia |
accumulation of bilirubin in the skin | jaundice |
patches of de-pigmented white skin | vitiligo |
persistent friction causes a gross thickening of the epidermis | callus |
area where blood has escaped and clotted in the tissue spaces | bruise |
acute trauma that causes a separation of the epidermal and dermal layers | blister |
a cut below the dermis, suturing helps speed up the healing process | deeper cuts |
healing is accompanied by the formation of granulations | large, open wounds |
a cut that only involves the epidermis | shallow cuts |
dried blood clot and fluids | scab |
consists mainly of fibrous proteins that forms from plasma, cells, and platelets | clot |
example is sunburn, superficial partial-thickness | first degree burn |
deep partial-thickness, blistering normally occurs, burn effects some of the epidermis and some dermis | second degree burn |
full thickness, destroys the epidermis, dermis and accessory organs, occurs when immersed in hot liquid, fire or corrosive chemicals | third degree burn |
skin graft, removal of a thin layer of skin from an unburned area and transplant it | autograft |
leaves extensive scars, burn too extensive, cadaveric skin from a bank is used to cover the injury, temporary covering that decreases the size of the wound and helps prevent infection and helps preserve deeper tissue | homograft |
