Explain how the heart rate is a good example of dual innervation in the autonomic nervous system. Include the nerves and neorotransmitters involved.

Solution

Ans Heart is resposoble for the dual innervation generally sinoartrial node of pacemaker is involved and this node is dually innervated by both divsions of heart.Sympethatic neurons are most proabably resposible for enhancement of heart rate as a result release in adrenergic stimulations and on the other hand parasymethatic nervous system results in release of cholinergic stimulations which leads to low heart rate
