Term | Definition |
---|---|
Afferent/Efferent | Afferent- signal traveling towards integration center from sensor Efferent- Signal traveling away |
Proteins | 1. primary (polypeptide, parathyroid H 2. secondary (coiled/bent polyp's 3. tertiary (myoglobin) 4. quarternary (multi polyP's, chemical changes) |
Cell volume | 1. hypotonic-h20 moves in, lyse 2. isotonic- same volume, no movement 3. hypertonic- loose h20, shrivel |
oxidation reduction | oxidases, hydrogenases, dehydrogenases. energry for muscle contraction and work |
Cell reproduction | 1. M-phase 2. prophase 3. metaphase 4. anaphase 5. telophase |
epidermal cell layers | 1. stratum basale 2. stratum spinsosum 3. stratum granulosum 4. stratum lucidum 5. stratum corneum |
skin glands | 1. sweat- eccrine-widespread, small, clear fluid apocrine- deep subq, larger, puberty 2. sebaceous- prevent h2o loss, in dermis 3. ceruminous |
Membrane potential | difference in charge slight - inside, +out, @ rest -70mV. 3 Na+ out / 2 k+ in |
local potentials | deploarization- MP moves toward 0. Inhibition-k+ moves out increase magnitude of MP, hyperpolarization- Mp moves away from 0, |
Heat loss | 1. evaporation 2. radiation 3. conduction 4. convection (negative feedback) |
