ENDOCRINOLOGY; HYPOTHALAMUS; ADH & OXYTOCIN by Professor Fink

Professor Fink first describes some of the major functions of the Hypothalamus of the Brain, including the Thermoregulatory Reflex Center, the Appetite/Satiety Reflex Center, Osmoregulatory (Thirst) Reflex Center and the Parturition/Milk Let-Down Reflex Center. The function of Antidiuretic Hormone (ADH; Vasopressin) is then described and the Negative Feedback Loop that regulates the tonicity of the body fluids.

I love how you emphasize the positive feedback mechanism of labor contractions!

[@cynthiadouglas-ybarra3824]

Professor Fink, I am a successful RN and I give you at least partial credit. Your classes made me think and now I'm encouraging my students to subscribe to your you tube channel. Keep up the good work.

[@stephaniebernal5100]

Teacher of the decade!

[@flaviagarcia10]

I love your classes! You explain the meaning of the words, mainly when they come from latin or greek. You use of ton of voice for emphasize things and catch our attention. You make clear analogies. The way you teach makes everything so easy to understand. Thanks for doing it with love. I'm never tired to listen to you. You make learning fun and easy.

[@ashnaali4029]

This is the best explanation on hypothalamus I have seen so far. You are a genius professor fink, has humongous amount of energy . Love your lectures 👌👌👌

[@oldhag287]

Favorite of mine. The concept of negative and positive feedback is crucial!

[@KingSexy]

I believe only Professor Fink knows how to teach. I had different science classes with different teachers, but they were waste of time and gave hard exams. Pro. Fink helped a lot to clarify the related topics.. Thank you Pro. Fink

Colostrom does indeed contain antibodies (which I stated on the video lecture). It also contains significantly LOWER amounts of both sugars & fats & calcium than mother's MILK. You are correct to point-out the presence of lymphocytes and growth factors, as well as proteins in general. The quote below is taken from Wikipedia. Thank you for your clarification. -- professor fink "Colostrum is very rich in proteins, vitamin A, and sodium chloride, but contains lower amounts of carbohydrates, lipids, and potassium than mature milk. The most pertinent bioactive components in colostrum are growth factors and antimicrobial factors. The antibodies in colostrum provide passive immunity, while growth factors stimulate the development of the gut. They are passed to the neonate and provide the first protection against pathogens." [Source: en.wikipedia.org/wiki/Colostrum]

[@kimho7258]

Professor Fink, I have viewed most of your lecture videos since 2014 for my science courses. I am North Cal so I can't attend your classes 😢😢😢

[@JennyPhan2014]

Really awesome lecture! Wish I would've taken this class in person. Only comment is that OXT receptors are in more places than just the uterus and mammary glands (i.e., amygdala, prefrontal cortex, nucleus accumbens), which are regions in both males and females.

[@professorfink]

Thank you for your kind words, Jenny!You are absolutely correct about the Oxytocin Receptors on neurons in the brain.However, I chose not to lecture on that (especially because their exact roles in HUMANS are still unclear).

[@JennyPhan2014]

Great video but supra optic is the one that releases ADH and paraventricular releases oxytocin! I don't understand how the students don't have to know alot of the rods/terminology! They are soo lucky, we're expected to know all of it. Now I just wish my prof was as great as him :(

[@conspiracytheorist2181]

If a mother doesn't breast feed the infant, the suckling trigger of the oxytocin release is not happening, so presumably less oxytocin is being released in the mother's brain. Does this diminish the level of emotional affection and bonding that the mother experiences with the infant, as compared with, say, a second child of the same mother who is breast fed? Because we can assume that the second infant would trigger more oxytocin. I'm thinking about the psychological feedback loop, and the consequences for the child's attachment status with the mother. The emotional bond could potentially be weakened on *both sides* of the relationship, not just the child's side.

[@professorfink]

+ConspiracyTheorist What you have proposed sounds logical, but I do not know of any scientific studies that have tested this and shown it to be correct.

[@conspiracytheorist2181]

professorfink Thank you for responding.

[@conspiracytheorist2181]

+Trinitro phenylnitramine Interestingly, in today's New York Times Health section, new studies were cited that demonstrate a reduced risk of breast cancer among mothers who breast fed their children as infants, among other health benefits.

[@heidihowe6846]

probably- b/c i found out that i was not breast fed and my father would come form his 12 hr shift and i was crying. My Mum left in in my crib all day crying- i guess. My father would pick me up and i would stop crying....I think drinking canned milk caused a lot of issues for me. Even after 48 hr's. My sis was breast fed. My late mother apologized for not breast feeding me- she said she just did what the Dr told her to do- The Dr told her to give me canned milk- IDK. why.

[@philipadjapong6095]

@@conspiracytheorist2181 I have read this statement somewhere too. Does it have to do with breast sucking in general? It sounds silly and weird to me though.

[@diangoodas]

This video helped me so much, I even got a ah haw moment...Thank u Professor Fink!!!.

[@yuniaguirre]

Part 2 please!!!

[@wassimabdou7649]

Profesor I heard that oxytocin is also called the love hormone and the release of the hormone makes you attached to the baby and that we administer it to prevent post partum depression. My question is who is responsible for this feeling since hormones are not related to feeling ? Is it the limbic system that is related to feelings or the oxytocin that is related to feelings ? Thank you profesor

Awesome! Thank YOU

[@matthauszerede]

Professor Fink, i just read a paper about the effects of oxytocin on males and how it helps the flow of sperm during ejaculation. When you say that this hormone doesn`t act on males you`re talking about only uterus and mammary glands?

[@professorfink]

All books and lectures are presented for a particular level of understanding. My lectures are intended to be an intermediate level of understanding of Human Physiology. EVERY topic can be presented at a more advanced, deeper and more detailed level. Yes Oxytocin does have other actions. I presented only the most important actions.

[@25sweetspicy]

very interesting

[@PepsiGurl93]

In summary: Posterior Pituatry-"Neuroohypothyisis"- releases ADH(negative feedback, retain water) and Oxytocin(positive feedback, uterine contractions, boob milk). Anterior Pituitary-"Adenohypothysis"- cuboidal epithetilial cells. Adeno=gland Parturition=Childbirth Breastfeeding is good because oxytocin causes muscle contractions that bring the uterus back to its shape prior to childbirth.

[@pavlosstag9625]

I don't get why the source of ADH is neurohypophysis and not hypothalamus could someone please explain me?

[@professorfink]

The neuron cell bodies are located "up" in the Hypothalamus. But the ADH neurotransmitter hormone is "released" from the synaptic knobs of the neurons "down" in the neurohypophysis. As long as you understand this, I think either answer is an acceptable one.

[@pavlosstag9625]

Now it's clear thank you very much :)
