Question 10

What are the two (2) types of Cholinergic receptors?

Answer 10

1. Muscarinic
2. Nicotinic

Question 11

What is the difference between nicotinic and muscarinic receptors?

Answer 11

Nicotinic receptors work in the central nervous system and at the neuromuscular junction. While muscarinic receptors work in both the peripheral and central nervous systems, they are mainly found in the visceral organs.

Answer 13

Preganglionic and Postganglionic neurons
