9.8 Control of heart rate in mammals

Students should:
$i Understand how the autonomic nervous system controls heart rate including: aortic and carotid baroreceptors and chemoreceptors cardiac centre in the medulla oblongata sympathetic nerve stimulated to release noradrenaline at the SAN parasympathetic nerve stimulated to release acetylcholine at the SAN. ii Understand the role of the autonomic nervous system in causing the release of adrenaline to increase heart rate.$
