ANSWER.
* Control of the heart rate and force of contraction are controlled by the
autonomic nerve system,where the sympathetic nerve system through
influence of epinephrine and nonepinephrine from the adrenal medulla
increases the heart rate,while the parasympathetic nerve system through
the vagus nerve decreases the heart rate.increase the heart rate above 100
per minute is known as Tachycardia,while a decrease in heart rate below 60
per minute known as Bradycardia.
Control of the heart rate and force of contraction are controlled by the [ Select] nervous...
5. Activation of the sympathetic division of the autonomic nervous system produces _____ in heart rate, and activation of the parasympathetic division produces _____. a. decreases, additional decreases in heart rate b. increases, additional increases in heart rate c. increases, decreases in heart rate d. decreases, increases in blood pressure
Please answer ALL questions. 1. Select the correct combination for a sympathetic increase in heart rate A. acetylcholine -- alpha receptors -- increased potassium permeability B. norepinephrine and epinephrine -- beta 2 receptors --increased permeability to sodium, potassium, and calcium C. acetylcholine --muscarinic receptors --increased potassium permability D. norepinephrine and epinephrine -- nicotinic receptors --increased permeability to calcium E. norepinephrine and epinephrine -- beta 1 receptors -- increased permeability to sodium and calcium 2. If there is loss of plasma...

Besides heart rate, name another factor that is also controlled by the sympathetic nervous system to affect cardiac output. Briefly explain why
select the right answer: question: Drugs with a positive inotropic effect: a) increase heart rate b) decrease heart rate c) increase force of cardiac contraction d) decrease force of cardiac contraction
The autonomic nervous system can change the rate of the heart by: (could have multiple correct answers) a) beta1 adrenergic receptor activation. Increases in cAMP lead to increased amounts of Na+ influx (though If channels) and Ca2+ influx of the pacemaker cells. This increases the frequency of APs of the pacemaker, and increases the rate of contraction. b) beta2 adrenergic receptor activation. Increases in cAMP lead to increased amounts of Na+ influx (though If channels) and Ca2+ influx of the...
