Anatomy and Molecular Basis of Autonomic Innervation of the Heart,) and contractile function (positive inotropy), whereas parasympathetic nerves diminish heart rate (bradycardia) and attenuate sympathetic effects on contractile function. Under normal conditions, the two systems are well balanced to maintain a normal response to external stimulation.

Clifford Nass,Erica Robles,Qianying Wangection of the postganglionic neural axons innervating the heart. Axonal degeneration develops within days after transplantation and leads to total depletion of cardiac norepinephrine stores and eventual disappearance of nerve terminals in the transplanted tissue, resulting in total cardiac denervation.

The Ouroboros Model, Selected Facets,. Most sympathetic neurons use norepinephrine as a primary neurotransmitter. Acetylcholine is the main neurotransmitter released by preganglionic and postganglionic vagal nerve terminals, which wrap around the heart and activate the parasympathetic nervous system. Sympathetic and parasympathetic sys
