my mother says we all have nicotine receptors in our brains. Lol! And we should all have a little nicotine. !?

Question

She also says my tongue was a fetus. She claims to have a medical licence. Susan E. Ingalls is her name is she lieing or nuts?

Answer 1

We all have the thing called "nicotinic receptors" in our brain. Nicotinic receptors are present in moderate to high density in the brain areas containing dopamine cell bodies. A little amount of nicotine would stimulate increase in dopamine production thus producing a "pleasure" effect. However, increased dopamine not only gives such pleasurable feelings but it also can adversely affect the following:
>>cardiovascular functions such as vasoconstriction, thrombosis and increasing blood pressure and heart rate.
>> lung functions such as bronchoconstriction, alveolar damage, and lung cancer .
Well, normally we do not need any amount of nicotine- nicotine as a very toxic agent.

Answer 2

Your brain DOES have a form of nicotine receptors as the first answerer says, however that doesn't by any means justify putting nicotine into your body, especially if you're putting arsenic and such in it at the same time.

Your body also has alchohol receptors in the brain. These kind of receptors are intended for extremely small intakes, the kind you are already getting through eating your veggies.

So to answer your question,

1) She is sort of lying that you have nicotine receptors.
2) She is definitely lying that we should all have some nicotine (assuming "a little" means on the scale of cigarettes)
3) She is indeed nuts

Hope that helps

Answer 3

We do have an entire nicotinic nervous system. And a muscarinic. You might want to do a web search on the autonomic nervous system.

Answer 4

I think she is referring to nicotinic acetycholine receptors. They aren't really "nicotine" receptors. They are receptors for the neurotransmitter acetycholine.
