Cards in this deck (46)
- 1Provides a barrier between highly ordered and regulated internal environment and the constantly changing chaotic environment outside.The integument
- 2Protects against infections as a physical barrier.The integument
- 3Major sensory organ, providing a source of........Pain, light and heavy pressure and temperature and sensation.
- 4What is the integument impervious to?Chemicals and water.
- 5The Integument does not protect us from U.V light. (True or False)False
- 6What is the epidermis?Most superficial of the three layers of the integument.
- 7What is the epidermis made of?Stratified squamous epithelium
- 8Constantly being regenerated from the basal layer.Stratified squamous based layer
- 9The outermost layer consists of dead keratinized cells, which protect.........against infection and desiccation
- 10Produces pigmented melanocytes to protect against UV radiationThe epidermis
- 114 epidermal layerStratum Basale (Basal Layer), Stratum Spinosum (Spinous Layer), Stratum Granulosum, Stratum Lucidum and Corneum
- 12Constantly undergoing mitosis to replace upper layers lost.Basal Layer
- 13Which layer maintains its cells attached to each other through desmosomes.Spinous Layer
- 14Populated by stem cells for keratinocytes and melanocytesBasal Layer
- 15Appears SpikeySpinous Layer
- 16Dead keratinized cells forming the outermost layer of the epidermisStratum Lucidum and Corneum
- 17Found in particularly thick skin in the palms and solesStratum Lucidum
- 18Cell deathApoptosis
- 19Which layer has large keratin and lipid granules in cytoplasm?Stratum Granulosum
- 20The Stratum Granulosum cells rapidly keratinize and undergo apoptosis. (True or False)True
- 21Cell Types of the IntegumentKeratinocytes, Melanocytes, Merkle's (tactile) cells, Dendritic (Langerhans) cells.
- 22Most common cellKeratinocytes
- 23Produces a waxy protein keratin.......which remains inside the cell and eventually kills it
- 24Melanocytes produceMelanin
- 25Humans vary in the amount of melanin produced in skin or by the number of melanocytes?Melanin produced in skin.
- 26Merkle's cells are....Tactile cells
- 27Dendritic (Langerhans) cells are.....Fixed phagocytes
- 28Early warning system of immune system located up to the stratum granulosumDendritic (Langerhans) cells
- 29Most superficial of the sensory receptor cells (stratum basale)Merkel's (tactile cells)
- 30Most of the thickness of the integument is made up of.....Dermis
- 31What is the Dermis made of?Dense irregular connective tissue, rich in collagen fibers and populated by fibroblast
- 32The avascular epidermis is not rich in ........Blood vessels, nerve endings, exocrine glands and the roots of hair and nails.
- 33The Dermis has regions of,Elastin fibers, which provide elasticity to the skin
- 34How is the dermis separated,Superficial papillary layer and a thicker, deeper reticular layer
- 35The two dermal layerPapillary layer, Reticular layer
- 36Accounts for about 20% of the total thickness of the dermis.Papillary Layer
- 37This is also the layer that contains elastinReticular Layer
- 38Cutaneous glands and roots are imbedded in this layer.Reticular Layer
- 39The rich bundle of capillaries in this layer supply the Stratum Basale.Papillary Layer
- 40The papillary layer is deeply folded into the papillae that contain-------corpuscles for --------------------Meissner's, tactile sense
- 41What is the dermis held loosely onto?The underlying muscle and bone by the hypodermis, and loose connective tissue.
- 42Who has more subcutaneous adipose, men or women?Women
- 43Adipose can thicken or thin, depending .........Calorie intake
- 44Adipose protects the body against ........Hypothermia
- 45Melanocytes decrease with age. (True or False)True
- 46Red-headed people produce what variant of melanin?Pheomelanin
