Neurotransmitters: Type, Structure, and Function
HTML-код
- Опубликовано: 23 июл 2024
- We know that neurotransmitters are signaling molecules that travel across the synaptic space to interact with receptors and propagate signals from one neuron to the next. But what are these molecules? What are their structures? How do they work? Let's get a closer look!

Acetylcholine has two major classes of receptors: nicotinic and muscarinic. Nicotinic is always excitatory and located on all skeletal cells. Muscarinic can be excitatory or inhibitory and is located on smooth and cardiac cells. Also good to note parasympathetic post ganglionic are cholinergic so they produce acetylcholine, but sympathetic post ganglionic are adrenergic so they produce norepinephrine and act on different receptors (alpha and beta).
Thankyou for knowledge
Really concise and informational video. Keep up the good work.
Thank you for explaining subjects slowly and clearly...you're helping!
I don’t know how you knew I have an exam covering neuropharmacology and NTs on Friday but if you could keep doing that that would be swell
You are awesome and keep up the great work. You have helped me and a lot of others.😁😁
This is the first time I understand the mechanism of neuroscience.thank u.
the unconventional part that i've not acquainted in, very helpful all this material
great video! helped with second year uni class :)
Easy to undersrand.Thank you so much.
Oh wow. I was just studying action potentials recently and now this comes up. You're a miracle dave.
Make sure to check out the tutorial immediately before this one, it's all about the action potential! Very thorough.
Exellent explainations!
So so helpful video... Keep up sir
Super lecture thanks Sir
First , Thank you very much for the video and wonderful details ,second , is it possible to know how to find out the mechanism how to analyze the problem of the patient and how to solve it , is there speceific tests to know where is this long chain brekdown and fix it , finally can you guide me how to know that
well done ,thank you
Very good video.
ThaNk yOU
I'm still trying to grasp the unconventional neurotransmitters. If they can move between cells through the membrane does that mean they don't transport via the vesicles? And what message do they give the other cell? Very confusing and I am trying to explain for an essay on the ECS.
Thank you so much!!!
Great lecture for laymen too. Thank you very much. It is understandable even if you aren't prfessional (I'm an engineer), also detailed enough and the content was very pointed, which was really important for me to pick some information fast for my thougts. You are an excellent lecturer, professor ! ;)
Hello! Great video!! Do you have any pharmacology/physiology books as a recommendation that talk about all the things mentioned in the video? Thank you!!! :)
Yoooo Dave love you bud
Thanks so much
Good video
Interesting ☺
Perfect👏
Great info! Which playlist will this be part of?
Biopsychology!
Oh my God ,this man is great
oh boy I sure do love neurons
Professor I have a question about subtituted tryptamines like DMT. I know they function through our serotonin pathways but would you classify it as a neurotransmitter? Thank you.
In my opinion they are not neurotransmitters per se but act as agonists of serotonine. They seem to be an aberration in mammals and only exist in tiny concentrations, so like a flawed byproduct or are created in certain diseases. Compared to other neurotransmtiters - they dont seem to have specialized enyzmes for further processing and dont seem to have unique coressponding receptors. Natural neurotransmitter have aswell some kind of re-uptake mechanism.
Yo, Dave, you delta-9-tetrahydrocannabinol friendly?
Hello, I have a question. What are the main neurotransmitters affected by THC. I had a really bad experience 4 years ago with an edible. My brain did not respond well to it. I am not sure which hormones were affected the most. I experienced severe depression, paranoia, anxiety, DP/DR. 4 years later I am wanting to come off of antidepressants. But I need to know the neurology of my brain and what I can take or do to help it heal from whatever the THC had done. Can you please offer me some advice. And yes I have a Psychiatrist who is aware of all of this and is helping me taper off of my medication. I am on week 3 of a 6 month taper. Never had depression before until I tried that edible.
You doing better now?
Thanks heavens.
I might be a nerd.
Welcome to the club!

A very informative video, but I hope the editor uses font and figure colors that are more light and gentle to the eyes, because some students watch these videos in series, and it might lead to eye strain (which I had, during @5:50). 😞
LOL bro that intro, just, why? 😂
Catagoey
Opioid peptides aka endorphins
THIS IS 1:19
i wont get bore if the videos would be lenthy i.e 21min and more so think of it more detailed videos
