A&P EXAM #2 QUESTIONS WITH 100%
CORRECT ANSWERS
\.Integument - ANSWERS✔-largest system of the body
\.Outer epidermis - ANSWERS✔-has no blood supply
\.inner dermis - ANSWERS✔-connective tissue
\.Accessory structures - ANSWERS✔-Hair, nails, multicellular exocrine glands
\.Epidermis - ANSWERS✔-"upon" dermis
\.subcutaneous layer - ANSWERS✔-fat layer, loose connective tissue
\.Funtions of skin - ANSWERS✔-protects
excretes
maintains body temp
synthesizes vitamin D3
stores lipids
Detects touch, pressure, temp
,\.True - ANSWERS✔-Epidermis is Avascular stratified squamous epithelium (no
blood supply!!!)
\.Keratinocytes - ANSWERS✔-protein synthesis (make keratin-waterproof barrier)
\.Thin skin - ANSWERS✔-Covers most of the body
has only four layers of keratinocytes
\.Thick skin - ANSWERS✔-for places w/ high amounts of friction
covers the palm of the hands and soles of the feet
has five layers of keratinocytes
\.Stratum Lucidum - ANSWERS✔-layer only found in thick skin. Clear layer
\.Stratum corneum - ANSWERS✔-exposed surface of skin, water resistant, shed
and replaced every two weeks (looks like corn flakes)
\.Stratum Granulosum - ANSWERS✔-The Grainy layer. stops dividing and starts
producing
\.stratum spinosum - ANSWERS✔-the spiny layer. continue to divide, increasing
thickness of epithelium.
, \.Stratum Germinativum - ANSWERS✔-where mitosis occurs (reproduction) the
germanitive layer.
\.Epidermal ridges - ANSWERS✔-what forms fingerprints?
\.Dermal papillae - ANSWERS✔-"tiny mounds" strengthen attachment between
epidermis and dermis
\.Melanocytes - ANSWERS✔-Give us our pigment; contain melanin; "black cells"
protect from UV radiation
protects from sun
\.Insensible Persperation - ANSWERS✔-the persperation that you dont even
realize occured (2 liters a day)
\.Sensible persperation - ANSWERS✔-The persperation you notice (vigorous
working out) water excreted by sweat glands
\.Dehydration - ANSWERS✔-from damage to stratum corneum
from immersion in hypertonic solution
\.Hydration - ANSWERS✔-results from immersion in hypotonic solution (eg
freshwater)
causes swelling of epithelial cells, evident on the palms and soles
