Document Summary
Title (150 characters including spaces) informative and reflect study include species. No direct measurement of symp activity: changes in map and hr can give indication. Don"t have to any change is significant. You can either give the difference of the numbers or the starting and ending numbers. Include in methods that any difference means p<0. 05. Then get broader: determine reasonable explanations for the observations. Sv determined by contractile force of heart and venous return. Signals from working muscles + signals to activate cardio system. Results in sympathetic response that increases hr -> co fig___ - also vasoconstriction in periphery counteracted by vasodilation in redistribution of blood to working muscles -> shown by decrease of tpr response for de (fig___) Co2 increase in blood -> ph decreae detected by central chemoreceptors -> somatic motor neuron received excitatory signals -> innervate muscles that aid in inspiration and expiration.
