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)
