11.2 Study Exam Questions.
1. What three mechanisms
regu- late the heart pacemaker, cardiac center, and the endocrine
system
2. What is the common name
for sinoatrial node?
pacemaker
3. At what rate does the SA
node tell the heart to beat?
How does the SA node
communicate this to the 60 and 100 bpm; it sends out an electrical impulse
heart?
4. What collective branch of
the nervous system is
associated with the cardiac
center of the heart parasympathetic branches
5. Which segment of the
nervous system directs the
heart to in- crease the
number of beats per
minute? Which segment of sympathetic stimulation; parasympathetic stimulation
the nervous system directs
the heart to decrease the
number of beats per
minute?
6. What is the function of
the baroreceptors
7. Which hormones released by Monitors blood pressure and send sensory
the endocrine system affect
the heart rate information back to the cardiac center stimulating
either the parasympathetic or sympathetic
branches
epinephrine and norepinephrine
