Key Learning Points
Nervous Control of The Heart
Sympathetic Nervous System Page 3
- The Sympathetic Branch(a) of the autonomic nervous system speeds up the heart.
- The Sympathetic Branch, like the parasympathetic branch effects, the SA node(b) atrial muscle(c) and AV node(d) and in addition the HIS Purkinje system(e) which is part of the conduction system and the ventricular muscle(f)
Baroreceptor Influence Page 4
- Baroreceptors(a) are stretch sensors for the autonomic nervous system.
- The Carotid Sinus(b) is a concentration of baroreceptors at the base of the internal carotid artery.
- Based on information received from baroreceptors, the vasomotor center(c) stimulates the parasympathetic(d) and sympathetic(e) nervous systems.
