34B Frog cardiovascular Physiology: computer simulation 1. What was the baseline lovingness ordain for the frog? autonomic nervous system: 59-63 bpm 2.Which wave is larger, the one for atrial parsimoniousness or the one for ventricular contraction? Why autonomic nervous system: Ventricular. It shows the capability of the ventricle as it pumps blood, and it is a thicker muscle to pump stronger as it contracts 3.At what time during the contraction cycle was it possible to make up an extrasystole? Ans: The time during the relaxation part of cardiac cycle. 4.By clicking the ninefold stimulus bottom and delivering 20 stimuli/ sec, were you able to make tetanus? Why or why not? Ans: No, because of the long absolute refractory period, it cannot be tetanized by multiple stimuli. 5.What happen to the heart assess with pneumogastric stimulation? Ans: HR slows and eventually stops during vagal stimulation 6.What happen during vagal escape? Ans: HR increases gradually. 7.List the frog heart rate for the following conditions: Ans: 49 Bpm with 5 C Ringers solution. 59 Bpm with 32 C Ringers solution. 8.Describe the resolution of tem on heart rate Ans: A decrease in temporary worker causes a decline in HR; increasing the temp increases the HR, therefore being a direct relationship amidst the two. 9.

Describe this effect match your prediction? Explain Ans: Yes, as temperature increases so does HR as in a fever, aforesaid(prenominal) affect with cold; temp drops, so does HR. 10.What was the heart rate after manipulation with pilocarpine? Ans: 44 bpm with pilocarpine. 11.Did this effect match your prediction? Explain. Ans: Yes, pilocarpine is a direct acting cholinergic agonist that decreases the HR. 12.What was the heart rate after treatment with atropine Ans: 70 Bpm with atropine. 13.Are the effects of pilocarpine and atropine the very(prenominal) or opposite? Ans: Opposite 14.Same question with adrenaline? Ans: 80 Bpm with epinephrine. 15.Did this effect prediction? Explain. If you motive to get a full essay, order it on our website: Ordercustompaper.com
