I love your vids! I watch them when I don't understand what I study but also when I don't want to study but I need to be productive. Your vids are great and I love watching them, it's so better than just studying with my notes. Thank you so much for making it all easier! Have a nice day :)
Definitely me brh🤣🤣😂😂 when u procrastinate u listen to these
Oxytocin-
Paraventricular nucleus.
Cervix-
Stretch receptor.oxytocin.
Gq phospholipase C.
DAG ca++.
IP3. Ca++.
Alveolar gland mechanoreceptor .myoepithelium.
Milk let down reflex.
Hypersecretion- ptosin.
Hyposecretion- uteto inertia.
Postpartum hemorrhage.
Thank you sir
🙏😊🥹
Making my way through your Endocrine playlist. Thank you so much for doing these videos❤️
Great video, as always!
As a side note, what he is describing at 13:50 is Sheehan syndrome.
Ischemia and necrosis of anterior pituitary due to PPH, Sheehan syndrome.
Next week I have a physiological exam, and your videos help me understand and save time
Friend showed me your page, really helpful as a 2nd year med student. Thank you Ninja!
now I'm on my 2nd year med student and I'm totally agree with you.
@@malirax354 now I’m on my 2nd year med student and I’m totally agree with you
@@hamedahmed3942 now I'm retaking my 2nd year final and I'm totally agree with you
Your videos are really Very helpful .... Especially during this lock down period.....i'm 1st yr mbbs student..... From India 🇮🇳
We are Penn State!!
Thank you so mucbh for these videos I don't know why this doesnt have more views and likes! They help so much with my classes!
thank you for sticking through the whole process of making this video
،
Dude, your videos are amazing, teaches me everything I need and more for my Physio class. Well Done
You are doing physiotherapy from where...
Are you a foreigner or Indian
All I can say is that you are good ..you are really helping and continue with the great job ..you helped me in biochemistry when I was in my second year now 4 th year you are helping me in pharmacology ..keep it up
Isn’t it produced in hypothalamus and released by posterior pituitary?
You are right
Yeahhhhhh
He has thought that already but he is talking about the nuclei within the hypothalamus that produce the hormone itself.
I think you a right
The hypothumus gland is near the chi flow of the palm on between the palm of hand and feet are hypothalamus muscle in the hand and foot in between is the chi flow of energy ❤
As per how you drew that baby facing upwards inside the uterus, it's gonna be hell of a delivery, lol
Anyways, love your videos, man.
I was born with my head facing upwards lol
Breech presentation. Poor mom!
Hahah! That baby is not stretching the cervix, that baby is closing his way out!
My body is producing oxytocin for you ........cause you explain so beautifully 😂😂❤️❤️❤️
I can also explain too, so your body can produce oxytocin for me too.
Thank you more than tons for all of your videos... It's incredibly educational, appreciated and generous!!!
Great for 1st year mbbs student india
This lessons are so better than actual school lesson to be honest lol.
When I get done watching all your videos I’m going to go take my Nursing board test ❤ I’m hooked .
Thank you from the bottom of my heart for your so clear and understandable explanations.
Thank you so much sir first year mbbs isn't so bad when you're there to help :DDDD
Why are you so amazing! Tell me what I can do for you to make more vids. How can I support?

Belated Happy teachers day sir and your team🥹🩷🙏🏻🫡🫡🫡🫡
If I had got such handsome teacher I would have never missed my lectures 😆 your videos are effective thank you
the human body/ mamal bodies are astonning. what is also astonishing is that we've figured out how some of these mechanisms you are explaining work. How?? haha. Human ingenuity is really something to behold.
Have been trying like mad to find a simple way to explain hyposecretion and the use of pitocin to augment labor in my birth class but really needed the refresher. This was PERFECT. I think I'm going to use a stuffed uterus and maybe straws to represent receptors.
You just helped me do well on my finals! TYSM
Would the positive feedback loop created during childbirth be an example of hypersecretion of oxytocin?
Yes
hypersecretion would indicate an abnormal amount of oxytocin being released, so I don't think so, since the positive feedback loop would be working as intended.
What about oxytocin as a neurotransmitter in the brain and its role in dopaminergic activity ?
love all your videos, well drawn and explained. they have been very helpful helping me learning how to explain to others x keep videos coming!! mia uk x
So helpful , as a 2nd year mbs student ... work was much easier to understand :)
thank you so much dear your lectures are really useful when I want read the anatomy book I gone confuse but in your lectures just peace of cake .
Ninja Nerds! Getting excited for science!
You are my hero!!! Respect for all your work and big heart ! ❤
Wow...u r such a great teacher, giving a very Clear concept in every video....well done mannn...
Me and my wife we secrete a lot of this oxytocin by scratchy caresses specially on our back after a few minutes you get tears and deep breathing involuntary and very very relax
Could you mention the effect of antipsychotic meds on the secretion of oxytocin from the posterior pituitary gland?
Zack can you do more vid on mental health and we need more videos about Maternity Super thank you!
I'm just gonna say my favorite part of this video was that uterus drawing lol Great content though! these videos are awesome supplementary content for anyone in med or nursing school
Dude I am just cracking the fuck up. The content is great but it just is fucking totally entertaining and there is a comical element here, even if it's just in my own head.
Your videos help me a lot in understanding the concept
Tq ninja! u expalined very clearly,really helpful for last minute studies...
Man, sometimes its hard to keep up with you...thank goodness we can pause and rewind!!
Awesome explanation sir
Yes. Totally subbed. I'm going through this right now, and it is fantastic. I'm in actual love. It's crazy cool ✌🏼.
Every time l finished the video I raelly loss the wards for thank you🤝😊💕
It's a breech baby?
thank you ninja nerd science !
making it soooo easy to understand......thanks alooot
Thank you so much for these videos
Hope you the best
Great! Highly recommended.
Thankyou so much bro... You so Clever... ❤️
You r underrated bro
10:49 Am I the only person who noticed that wink? 😭😂
Student Midwife here... your videos are getting me through my degree haha
When oxytocin is released, it’s presents isn’t selective, or is it? That same hormone would still hit the uterus without a baby? Curious
Phenomenal lecture 👌
@Ninja Nerd Lectures
Could you explain the effect of oxytocin on the lelevl of pain during menstrual period, please?
If one is low in calcium or other electrolytes, can the hypothalamus inhibit Oxytocin production?
My guess is oxytocin would be the least of your worries if your plasma levels of calcium or other electrolytes are very low (especially if this is associated with severe dehydration). But rather than the hypothalamus actively inhibiting OT due to the deficiency, I would say that the nerve conduction would be impacted and therefore result in sub-optimal OT secretion + signalling. Fear, anxiety and stress (and the pathways associated) can inhibit OT synthesis, however.
I love your videos - but you're stressing me out with that complete footling presentation - in labour no less! 😅
Your such a great teacher!!
thank you so much it's very helpful
You said the baby is stretching the cervix - you know (I hope) its actually other hormones effects on the uterus causing contractions (labor) shortening the longitudinal muscles and lengthening the vertical muscles of the cervix. Not the baby ;)
Sir plz one vedio
Topic:- Psysiological responses of exercise in hot conditions
Subhan Allah ❤️❤️🥰
Thank you so much 💕💕
you are really helpful, thank you !!!!!!
شرح جااامد جدا ❤️❤️😂🇪🇬
Heavily underated
I was a little bit confused that you said oxytocin is CAUSED by male ejaculation, but later you say that it stimulates/causes male ejaculation. Is it sort of the sexual arousement and especially right before ejaculation, stimulates oxytocin, and then that causes the actual ejaculation? Maybe someone can explain it to me
Btw your videos are amazing
I WANNA DO BAD THINGS TO YA!! I WANNA MAKE YOU YELL...
I WANNA DO BAD THINGS TO YA!! DON'T WANNA TREAT YOU WELL...
God bless you Doctor!
Thanks
+Sr Brt you're welcome!
Very helpful sir 👍
Please can you do other physiology lectures like on GIT and brain and netvouse system please please
6:38 I think the suckling should be on the aureola and not the nipple. Right? Not sure.. 🤔
Thank you so much this is very helpfull 👍🏻
Many many many thanks Ninja
Thnxx... It helped me alot😊😊😊
Please can this oxytocin open up the cervix while in labor because I have c section before but I don't want another c section again because am scared
Thank you!
you are the best
Thankyou sir
Amazing!
Thank you
Well I would have gulped all this lecture in if I had not started my OBSTETRICS posting in Medical school.
You need to review this video as there some errors in some of the basic function about Oxytocin you discussed.
So fantastic💙😔
Thank you 🙏
Hello, what lowers oxytocin, does dopamine inhibit it, or serotonin . . .
if you isolate urself your oxytocin levels will drop and it will cause anxiety
Thank you Soo much
Intercorse in the mid of 2nd trimester can cause utrine contration and harm for baby to cause miscarriage due to oxytocin that naturally release during foreplay????
Progesterone is secreted all through the pregnancy state. Progesterone demodulates Oxytocin receptor, ensuring carrying the baby till term if there are no precipitating factors that can induce Labor.
During Labour, there's an abrupt drop in Progesterone, and concomitant peak in oestrogen. This modulates the action of Oxytocin receptor, and causes expulsion of the products of conception.
Useful
really like your vids but my vocab is just too narrow to understand all the information =(
Excellent 😊
everytime u help me do well on a med phys exam I get a rush of oxytocin
Good topimaster.👌
😅👍👍
Which hormone is produced in explusion of milk from breasts when baby sucks it?is it prolactin or oxytocin?
Do you have the chinese charecter for "love" tattoo'ed on your back?
Wow!~ just wow!
VERY NICE
TnQ sir♥
SIR
YOU ARE SO AMAZING
