People SO need to save their money from paying these OUTRAGEOUS tuition fees. ESPECIALLY when there are WONDERFUL breakdowns like this. This is ABSOLUTELY amazing! THANK YOU VERY MUCH!!!
This just showed in my FB wall, shared by a friend, and, hey, a penguin prof, let's see it! Well, now I'm here literally crying (really!) for the emotion to have seen the light and a "structure" in something that has always been dark and hard to understand to me Thank you so much!
THANK YOU SO MUCH!!!!!! This was so clear and easy to understand. You saved me from hours of meaningless meandering on the internet and in my textbook! Awesome video!!!!!!
Do you know that YOU ARE MY HERO you make everything so much easer with your sweet voice and unique way of explanation! A lot of your video have helped me A LOT. Thank you so much for everything, you're an amazing educator
Great job simplifying what can seem like a complex, intimidating system to students seeing it for the first time! I tutor and this is a very clearly done explanation. Thank you! God Bless!
hey i just wanna say thank you soo much for your lessons youre much more better than our Dr. i think he needs to watch this. and i just shared that video with my friend. thanks again n keep it up.
The soma of sensory neurons are contained in the dorsal root ganglia just a short distance outside the spinal cord, and are pseudo-unipolar neurons, which do not have dendrites, but rather one projection (hence uni-polar) from the soma which bifurcates into two AXONS, one of which is long and goes to the receptor, and the other shorter one returns via the dorsal root into the spinal cord. The fact that the longer one from the receptor is an axon is what allows the strength of the signal to be maintained from the receptor than a dendrite would allow.
A very nice vid! However, you create some confusion at the very beginning (1:00) - when you draw a sensory neuron. This purple neuron seems to have it's body (indicated by the star) in the CNS, while it should normally be closer to periphery. Also it's projection conducting nerve impulse from a receptor to the body looks like the only long axon, while it should be one of many dendrites. In other words, this neuron has wrong direction.
@Yevgen Kiosya, I think you're mistaken, in that the soma of sensory neurons are contained in the dorsal root ganglia just a short distance outside the spinal cord, and are pseudo-unipolar neurons, which do not have dendrites, but rather one projection (hence uni-polar) from the soma which bifurcates into two AXONS, one of which is long and goes to the receptor, and the other shorter one returns via the dorsal root into the spinal cord.

So much easier to understand, Thank you so much why do professors like to make themselves sounds cleverer by using such complicated words to explain something so simple :D
Thank you very much! I have a question here, since you seem to be proficient in neuroscience: how is the sympathetic nervous system triggered by visual cues? does the signal come directly from the visual cortex to the pre-ganglionic neuron via the spine? or does it have to pass through the amygdala and other regions in the hind brain region? I am asking this because I presume that an animal wont have much time to react in situation of a visible danger, hence can the amygdala etc be by-passed?
Actually visual input is pretty quick. Less than a few microseconds. Most of the time it will be a cranial/brainstem reflex if an animal is in danger. At the same time some neurons would go down and activate motor neurons in the ventral horn of the spinal cord which will release acetylcholine/norepinephrine to trigger fight or flight response. It would be somatic nervous system activity at point, not so much autonomic.
Does anyone know if calcium still enters the preganglionic neuron via voltage gated channels in order to release ACh to the ganglion? And is the action potential started again in the postganglionic neuron because Na diffused in after ACh binded causing the cell to depolarize?

Wow.. never thought studying the synaptic pathways could be such fun and actually so uncomplicated... Thank you Penguin Prof!!!!! You are ACE!!
You have an amazing voice that is pure sunshine. You could wake the dead with that voice.
Iam a prof Anaesthesia It is one of best ANS Vedio I saw I will recommend this to my ug pg students. Thank u
Thanks SO MUCH for letting me know!!!
You have an amazing talent, you explained in a clear way. That's a great job. Please do videos, don't stop ur work. Spread the knowledge as you can
Thank you, I will!!!

Thank you so much!
I have an A&P final and I'm so glad I found you just in time!! I subbed, thank you Penguin Prof.
Finally a video of the ANS involving receptors and where the targets are!!! thank you!!!!!!
Such a helpful video! Thank you so much!! I love the way that you explain the functions of the body. Makes it so much easier to understand.
Thank you so much! I cannot help myself but to post a thank you comment here. It helps me a lot to understand the differences of three pathways.
THANK YOU SO MUCH!!!!!! This was so clear and easy to understand. You saved me from hours of meaningless meandering on the internet and in my textbook! Awesome video!!!!!!
spent the entire day reading about this.. watch this once and suddenly it all makes sense !!!
+Claire Amie Woo hoo!!! Excellent! Thanks for letting me know!
Simply superb I am prosthetic engineer working on EMG sensors you saved my life.
I am so glad to hear that!!! Thanks for watching!
Do you know that YOU ARE MY HERO you make everything so much easer with your sweet voice and unique way of explanation! A lot of your video have helped me A LOT. Thank you so much for everything, you're an amazing educator
Thanks. Simply the best video to explain neuro-receptors
Great job simplifying what can seem like a complex, intimidating system to students seeing it for the first time! I tutor and this is a very clearly done explanation. Thank you! God Bless!
Spectacularly well-explained.
I just can't even begin to... Amazing!!! Thank you so much
Thank you thank you thank you thank you so much mam. You have explained so nicely each and every thing so clearly in just 12 mins
Best video I have seen yet on this topic!
Wow - thanks so much! Glad it was helpful!
thank you so much penguin prof.
easily understood with your lovely voice
I have exam in a few hours...you are really a lifesaver!!
You are funny and explain things so I can understand! Thank you!
Thank you, this really helps! I also love the voice :-) You made it sound a lot more interesting rather than boring and daunting.
Thank you so much! I learned more here than in my college class!
PenguinProf, you're AMAZING!!!!
Great job.thank you so much for the so helpful video
I have to learn this for university admission test, and I didn't understand it at all, till I saw this video. Thank you!!!
hey i just wanna say thank you soo much for your lessons youre much more better than our Dr. i think he needs to watch this. and i just shared that video with my friend. thanks again n keep it up.

somehow your descriptions seem to sit me and feel less like jargon, thank you
YOU ARE THE BEST!!!
Thank you for this!! Very helpful!!! =)
Thank you so much!!!! It looks so much easier now :)

Thankyou, you made it really simple :)
THANK YOU SOOOOO MUCH!!!!!!!!
This is AMAZING!!!!!!!!!!! Can't stress that enough. :D
YOU ARE AWESOME, YOU MADE IT SO MUCH EASIER THAN MY PROFESSOR LOL
+lynda idir Thank you for watching!!! The ANS drives people crazy but really it's not so bad after all... keep at it!
HollyS**t - This updated lecture is a very different presentation.
thank you so MUCH !!!!!!
Simplifying and making your videos fun makes you brilliant! Be my friend! :D
Mariana Braga hi
Thanks so much, that unravelled my confused brain!
So much easier to understand, Thank you so much
why do professors like to make themselves sounds cleverer by using such complicated words to explain something so simple :D
mucho gracias sañora
De nada!

Do as many videos as you can
I'm trying!!! 🐧😀🐧
amazing
thank u so much its really helpful
It's amazing 😍😍❤
awesome
how adrenaline is secreted?
either direct from ganglion or ACH convert into adrenaline
Does anyone know if calcium still enters the preganglionic neuron via voltage gated channels in order to release ACh to the ganglion? And is the action potential started again in the postganglionic neuron because Na diffused in after ACh binded causing the cell to depolarize?
You talked about the adrenal gland above the kidney... If you need a kidney, just let me know.I wil give you mine 😂
Wow - that's quite an offer! Hopefully that won't be necessary!!!
You are my life
Video starts at 0:48
tq
Is there. A summary or a mind map ?
+Sehli Mohamed The summary is at around 11:44 of the video. :)
a hundred likes from me! thank you!!!!!!!!!!!!
Oh my god fuck my textbook after this
Is the most useful video thanks
Like and subscribe ❤️💋
I love u
Thank you very much
