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 :)

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

@mohammedalyami7070 Год назад

You are right

@nafisatoyiza5869 Год назад

Yeahhhhhh

@kofipapa2886 Год назад

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

@staceymurray9644 Год назад

I think you a right

@staceymurray9644 Год назад

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 ❤

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

@lisagarlick7060 6 лет назад

Yes

@yngfljm2277 Год назад

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.

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.

@znrgybalance8703 5 лет назад

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

@nicholastaranto6466 5 лет назад

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.

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 ;)

@williamdissing1041 2 месяца назад

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

@hassantimilehin7643 Год назад

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.

@NatureLover78258 2 года назад

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 Год назад

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.
