covering of an organ that contains an epithelial tissue layer and a connective tissue layer
Lines all body cavities that open to the exterior body surface; often adapted for absorption or secretion
Lines open body cavities that are closed to the exterior of the body; _______ layers separated by ______ fluid; two layers to add extra protection; fluid prevents friction
connective tissue membrane; found in movable joints (where bone meets bone); lines fibrous capsules surrounding joints; secretes synovial fluid
small structures found within the skin; e.g. sweat glands and oil glands in dermis, hairs, nails
layer underneath dermis; not part of the skin; anchors skin to underlying organs; composed mostly of adipose tissue
stratum corneum, stratum lucidum, stratum granulosum, stratum spinosum, stratum basale
layers of epidermis, outside to inside
layer of epidermis which only occurs in thick skin, like palms of hands and soles of feet
top layer of epidermis; found all places where skin is found; shingle-like dead cells
Orange-yellow pigment from some vegetables; gets absorbed into skin through blood vessels, which can make you an orange color
Red coloring from blood cells in dermis capillaries; oxygen content determines the extent of red coloring; when it is bound to blood, skin turns bright red
fancy word for redness due to embarrassment (blushing), fever, hypertension (high blood pressure), inflammation, or allergy
whitening of skin due to emotional stress (fear, anger) or anemia (lack of iron), low blood pressure, or impaired blood flow
abnormal yellow skin tone due to liver disorder in which bile pigments are absorbed by body tissues
produce oil, most with ducts that empty into hair follicles, glands are activated at puberty, found everywhere except your palms and the soles of your feet
type of sweat gland that opens via duct to pore on skin surface (secretes sweat through pores); found everywhere, including palms of hands and soles of feet
type of sweat gland where ducts empty into hair follicles (secretes sweat through hair follicles); found in axillary (armpit and genital) regions
composed of mostly water, in addition to metabolic waste and fatty acids and proteins in the case of apocrine; function is to help dissipate heat, excrete waste products; acidic nature inhibits bacteria growth; odor is from associated bacteria
smooth muscle that attaches to follicle; when it contracts, goose bumps appear on skin surface
Boils & Carbuncles
painful, pus-filled bumps that form under the skin caused by bacteria infecting one or more hair follicle
common, chronic (long-lasting) skin disease in which cells build up rapidly on the surface of the skin, forming thick, silvery scales and itchy, dry, red patches that are sometimes painful; cause unknown; symptoms triggered by trauma, infection, stress
third degree burn
burn which destroys entire skin layer (epidermis & dermis & possibly hypodermis); burn is gray-white or black
Basal cell carcinoma
Least malignant, most common type of skin cancer (abnormal cell mass); arises from the stratum basale layer of the epidermis; appears as an abnormal mole on the skin
Most deadly form of skin cancer; cancer of the melanocytes (melanin-producing cells in stratum basale); metastasizes (spreads) rapidly to lymph nodes & blood vessels; detection uses ABCD rule to identify abnormal moles
infection that develops in the moist areas between your toes and sometimes on other parts of the foot; causes itching, stinging & burning
(also called fever blisters) fluid-filled lesions caused by herpes simplex virus type 1 infection; appears as red blisters on lip
inflammation of the skin (red, itchy rash) caused by direct contact to certain substances, such as soap, cosmetics, jewelry, or weeds, including poison ivy or poison oak
