Which of the following isare characteristic of the parasympa

Which of the following is/are characteristic of the parasympathetic nervous system, but not of the sympathetic nervous system?

A ganglia in or near target tissues

B nicotinic receptors on postganglionic neurons

C muscarinic receptors on some target tissues

D 1 receptors on some target tissues

E 1 receptors on some target tissues

Solution

A. ganglia in or near target tissues. The parasympathetic nervous system is a slower system that moves along longer pathways. Preganglionic fibres from the medulla or spinal cord project ganglia close to the target organ. They create a synapse, which eventually creates the desired response.
