Homework Answers
1) Correct answer : Option E
Muscarinic and nicotinic receptors are cholinergic receptors and they bind exclusively to acetylcholine
Where as alpha 1 and alpha 2 receptors bind to epinephrine and nor epinephrine
2) Correct answer : Option A
Parasympathetic post ganglionic fibres binds to acetylcholine but not epinephrine
Preganglionic neurons of both sympathetic and para sympathetic neurons release acetyl choline
They differ only in post ganglionic neurons
Sympathetic post ganglionic neurons - epinephrine
Para-sympathethic post ganglionic neurons - acetyl choline
3) Correct answer : Option E
All the above statements are correct
None of them are incorrect

11. Acetylcholine is both an excitatory and inhibitory ligand depending on the location of its receptor. What does Acetylcholine do that makes it "excitatory"? a. It causes a cell membrane to depolarize and produce Excitatory Post Synaptic Potentials b. It opens K+ ion channels when it binds to its receptors c. It causes a cell membrane to hyperpolarize 12. The bonding of Acetylcholine to its muscarinic receptors on smooth muscle causes gated K+ channels to close. This action is described...
