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 :)

Next week I have a physiological exam, and your videos help me understand and save time

[@sapnakarunathilaka6447]

Isn’t it produced in hypothalamus and released by posterior pituitary?

[@mohammedalyami7070]

You are right

[@nafisatoyiza5869]

Yeahhhhhh

[@kofipapa2886]

He has thought that already but he is talking about the nuclei within the hypothalamus that produce the hormone itself.

[@staceymurray9644]

I think you a right

[@staceymurray9644]

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 ❤

[@Joniedelman]

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.

Yes. Totally subbed. I'm going through this right now, and it is fantastic. I'm in actual love. It's crazy cool ✌🏼.

[@michael_leclezio]

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.

Great! Highly recommended.

[@josetrujillo738]

Ninja Nerds! Getting excited for science!

[@Hegeleze]

Would the positive feedback loop created during childbirth be an example of hypersecretion of oxytocin?

[@lisagarlick7060]

Yes

[@yngfljm2277]

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.

[@arturzapotoczny2462]

What about oxytocin as a neurotransmitter in the brain and its role in dopaminergic activity ?

[@rajbogawat6583]

making it soooo easy to understand......thanks alooot

[@stephenshoop6716]

Could you mention the effect of antipsychotic meds on the secretion of oxytocin from the posterior pituitary gland?

[@MrKen59]

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

[@laibashahid9418]

gud job!

10:49 Am I the only person who noticed that wink? 😭😂

Do you have the chinese charecter for "love" tattoo'ed on your back?

[@znrgybalance8703]

If one is low in calcium or other electrolytes, can the hypothalamus inhibit Oxytocin production?

[@nicholastaranto6466]

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.

really like your vids but my vocab is just too narrow to understand all the information =(

[@jasperbrooks2118]

Hello, what lowers oxytocin, does dopamine inhibit it, or serotonin . . .

[@Justanobodybro]

if you isolate urself your oxytocin levels will drop and it will cause anxiety

[@sophiakchouk2242]

everytime u help me do well on a med phys exam I get a rush of oxytocin

[@beautyskitchen4761]

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

[@caprimungeam662]

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 ;)

[@adityasinghjodha3788]

Good topimaster.👌

6:38 I think the suckling should be on the aureola and not the nipple. Right? Not sure.. 🤔

[@NatureLover78258]

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????

[@hassantimilehin7643]

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.

[@jeffshirton374]

It's a breech baby?
