@user-bx2cs8nt9t 8 лет назад

Hmmm. What are some of the different factors that can contribute to hormonal imbalances? Since the hypothalamus and the pituitary gland regulate so many hormones, why is it some people experience a deficiency or an excess of only some of the hormones rather than necessarily all of them when there is a hypothalamic or pituitary dysfunction? If the hypothalamus was, for example, not properly distributing GnRH and TRH, how would that affect the pituitary gland's release of FSH/LH and TSH?

This really makes me wonder if there is a connection between my high level of TSH...Hypothalamus constantly producing TRH to send to the pituitary to make TSH, and my neuropathic gut pain (visceral hypersensitivity) - pain generated in the hypothalamus. Interesting. Maybe when I start levothyroxine and TSH is normalised I will find out. Whilst this is not typical, it could be possible in my case.

@Politickticktickin 6 лет назад

It detects markers in the blood and releases the appropriate hormones. For instance, if it finds that testosterone is too low in a nigga's blood compared to the baseline level, it will release GnRH, which will trigger LH and FSH production in the anterior pit gland, which will stimulate the dude's nuts to produce testosterone. As for bitches, it's just swapped with estrogen and ovaries. Fact up, curry nigga.

Regarding PRL, the hypothalamus secretes both inhibitory and excitatory hormones that regulate prolactin secretion.

@corkey29 8 лет назад

hypothalamus communicating with the pituitary via the portal system would not be considered paracrine because of the utilization of the blood stream. This would be classified as endocrine signaling.

@roanclairelabio2642 Год назад

hi? what are the hypothalamic neuropeptides?

@sarahfellows3074 2 года назад

What I am keen to learn is the reason why or how the hypothalamus knows which hormone it should release. Fir example, I have learned that in body temperature regulation, if the blood going through the capillaries is either too hot or too cold, then the relevant nuclei in the hypothalamus respond by sending a message down to the veins to either dilate or constrict, to the skin to shiver or to sweat . So that heat is conserved or dissipated. I am interested to know how the hypothalamus recognises what the body needs and does depending on the outside stimulus in more detail. Cab anyone help? Many thanks For example, say someone saw somethung thar they found attractive. The image would enter through the eyes go to the optic nerve and back to the occipital lobe where the image would be interpreted as attractive. Then, it must somehow go from the outer cortex into the hippocampus and into the hypothalamus to release certain hormones in the pituitary which I imagine then kicks off the release of oxytocin hormones and others, in the body? But how does the hypothalamus detect oh my human perceives this image as attractive? If someone could help illuminate me I would be very grateful.

Why does the communication of the Hyothalamus and Anterior Pituitary through a portal system considered a paracrine secretion? Is it not endocrine? if not please explain to me, I'm confused. Thanks!

@alexanderpugmire6600 8 лет назад

because endocrine signals are long distance hormonal signals ... the study of hormones was called endocrinology before autocrin and paracrin functions were found so it was to late to rename things

@LeoBrightLight 8 лет назад

I agree it's too late to rename things, after all the medical world is constantly changing. Hence, books are constantly revised. paracrine is cell to cell communication, autocrine is to itself while endocrine is a communication via blood flow.

@momenakhatoon5996 9 месяцев назад

I am a little confused, because in the previous video (@ ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-ER49EweKwW8.html), it was written that the Hypothalamus will release ADH / Oxytocin, but in this video it is written that the posterior pituitary release ADH / Oxytocin. Can they be interchangeable??

@shivangirawat797 7 лет назад

@dejanmarkovic3040 3 года назад

Wait, how can it be that simple? What about how other regions affect the hptlms or the pituitsry or vice versa? When I hear prolactin, I think post nut clarity, bit also pro-lactin...sounds like estrogen to me. But I paused the video amd googled it...turns out estrogen inhibits prolactin, while dopamine induces it...and where does T come in all thst? The more you know, the less you know...god damn it...and how does all this manifest functionally? How can you talk about fsh without dht, is there a longer video on all this on your channel? I truly dig this khanacademy videos, but was a bit too reductionist, even for a lay simpleton like me...bit still, thank for for clarifying all those acronyms, I'm gonna gk make some notes now. Edit: Sry, I just saw a bunch of related videos in this topic delving deeper into many of those..

@krijgsmand77 7 лет назад

I thought GH from the pituiritary goes to the liver where it is converted into IGF1. Doesnt that mean that 'flat peg' is incorrect? Since GHis not a direct hormone then... Anyone who has the answer?

@PavanMehat12 7 лет назад

That is correct GH effect on growth is indirect as you said because it acts on the liver to increase IGF-1 production which acts an endocrine function. Further it acts on bone and other connective tissue to release IGF-1 as a paracrine factor. But GH has other direct functions on the liver. It acts on the liver to increases gluconeogensis, adipose tissue to increase lipolysis and on muscle to increase amino acid uptake and protein synthesis. So in terms of GH's growth actions it is indirect, but in terms of its metabolic effect it is direct. However, I think the reason it is classified as direct it is not acting on another endocrine gland (ex. TSH on thyroid). But it is important to realize that although classification systems are absolutely essential to medicine, they is a degree of arbitrariness in classifying things, and every classification system will have grey areas. But an excellent question as this is a more sophisticated detail about the ever complex endocrine system.
