In the systemic circuit, the hearts _______ half pumps blood to all body regions; then blood flows to the heart. a. left; deoxygenated; oxygenated b. right; deoxygenated; oxygenated c. left; oxygenated; deoxygenated d. right; oxygenated; deoxygenated
Damage to what brain area may impair autonomic regulation of heart rate? O pons medulla O midbrain O thalamus basal nuclei O cerebellum
Which of these will increase the heart rate? sympathetic stimulation of SA node parasympathetic stimulation to the SA node the application of adrenalin (epinephrine) to the SA node O A and C O All of the above
Which of the following structures acts to carry electrical impulse to the ventricles? chordae tendineae Purkinje fibers papillary muscles SA node
Which of the following provides parasympathetic input to the SA and AV nodes of the heart? Adrenal gland (suprarenal) O Vagus nerve O all of these choice are correct O Cervical paravertebral ganglia
When the SA node fails, the AV node establishes a new intrinsic heart rate. This will result in Increased parasympathetic output to the SA node Increased blood pressure Increased blood flow through the pulmonary circulation Decreased cardiac output As Decreased sympathetic output to the SA node 20
In the lab, symphatetic stimulation of the heart will decrease heart rate increase heart rate O bring no change to heart rate because of the presence of sinoatrial node
An embolus lodged in the circumflex artery could impair blood flow to what portion of the heart? O right atrium O right ventricle O left atrium O all of the above
If you were running late for lab and had to run to get there on time, the sympathetic neurons of your autonomic nervous system were likely activated and releasing norepinephrine; what immediate effect might this have had on the blood pressure measured in your brachial artery? Increased stroke volume and heart rate to decrease blood pressure Increased stroke volume and heart rate to increase blood pressure Decreased stroke volume and heart rate to decrease blood pressure Decreased stroke volume and heart rate to increase blood pressure DERMA person
Sympathetic nervous system stimulation cases which of the following during exercise? vasodilation and venodilation vasodilation vasoconstriction and venoconstriction vasoconstriction
Which of the following statements best describes the actions of the neurotransmitter noradrenaline in the heart? Noradrenaline acts on α1-adrenoceptors in the sinoatrial node to increase heart rate. Noradrenaline decreases the rate and force of contraction of the heart. Noradrenaline increases the rate, but not the force of contraction of the heart. Noradrenaline acts on β1-adrenoceptors in the sinoatrial node to increase heart rate.
In the absence of neural and hormonal influences the SA node generates action potentials at a frequency of approximately 100 times per minute. However, the resting heart rate is approximately 70 beats per minute, which suggests that: O the parasympathetic nervous system has more control over heart rate while at rest O the sympathetic nervous system has more control over heart rate while at rest the heart is undergoing vagal escape while at rest the heart is not autorhythmic
