Skin Practice Exam Questions Correctly Answered.
integument - CORRECT ANSWER a.k.a. skin
means "covering"
epidermis - CORRECT ANSWER outermost protective shield of the body
NOT VASCULARIZED (gets nutrition by diffusion through the tissue fluid from blood vessels in dermis)
epidermis - CORRECT ANSWER skin layer composed of EPITHELIAL CELLS
dermis - CORRECT ANSWER tough leathery skin layer
VASCULARIZED
dermis - CORRECT ANSWER skin layer made of FIBROUS CONNECTIVE TISSUE
hypodermis (superficial fascia) - CORRECT ANSWER subcutaneous tissue just deep to the skin
technically NOT SKIN, but shares some of the skin's protective functions
hypodermis (superficial fascia) - CORRECT ANSWER consists of mostly ADIPOSE & some AREOLAR CONNECTIVE TISSUE
hypodermis (superficial fascia) - CORRECT ANSWER stores fat (shock absorber & insulator) thickens when one gains weight (breasts & hips females... anterior abdomen males...)
hypodermis (superficial fascia) - CORRECT ANSWER archors skin to underlying structures (mostly muscles) loosely (enough that the skin can slide relatively freely over them)
epidermis - CORRECT ANSWER made of keratinized stratified squamous epithelium
4 distinct cell types (keratinocytes, melanocytes, merkel cells, langerhans' cells)
4/5 distinct layers (stratum BASALE, stratum SPINOSUM, stratum GRANULOSUM, stratun LUCIDUM, stratum CORNEUM)
keratinocytes - CORRECT ANSWER produce KERATIN (fibrous protein)
keratinocytes - CORRECT ANSWER tightly attached together by desmosomes
keratinocytes - CORRECT ANSWER created in stratum basale next to the basement membrane
keratinocytes - CORRECT ANSWER move upward by new cells being made underneath
keratinocytes - CORRECT ANSWER flattens out when nearing the surface
when dead- scalelike structures a little more than keratin-filled plasma membranes
keratinocytes - CORRECT ANSWER completely replaced every 25-45 days
callus - CORRECT ANSWER thickening of epidermis caused by persistent friction
melanocytes - CORRECT ANSWER spider shaped cells
