@khanacademy Was there meant to be a second part to this video? You left the video saying "next we'll talk about how you have to have the right amount of a hormone or things will go awry", but the next video in the playlist is about meningitis... ?
@b562r The pituitary gland is itself regulated by the hypothalamus, so in that sense the latter would be called the master master gland! :) It really depends, some people give the title to the pituitary gland whereas others prefer to give it to the hypothalamus. The important thing is that out of this "misunderstanding" you now know the relationship between the pituitary gland and the hypothalamus! Hope this made sense. :) - First semester medicine student.
@zatoichi37 According to Sylvia S. Mader, "The thyroid gland is composed of a large number of follicles. Each follicle is a small spherical structure made of thyroid cells filled with triiodothyronine (t3), which contains three iodine atoms, and thyroxine (t4), which contains four."
@GwennyN T3 is secreted only in very small amounts from the thyroid gland. It is not the major product. T3 derives mainly from the peripheral deiodination of T4. By no means would the ammount of T3 produced by the thyroid be enough for a person to live. In any case T4 is inactive whereas T3 is the active form of thyroid hormone.
Very nice! Will be waiting for the next video. I remember when studying for the MCAT it had broken up adrenal into ad + renal as explained in the video, and I was like, OMG how have I never noticed that before?! One of those "...duh" moments. Interestingly, most medical terms make sense if you take a moment and consider their etymology ;) Also helps in remembering them.
Adrenal = adjacent to the renal organ. My reaction was the same as Sal's -- it probably should've been obvious, but I def. never put 2 and 2 together until Dr. Sneeze mentioned it.
wireless signals, wow, amazing way of seeing it, never thought of it that way and never knew the pituary gland does that much, thank you fascinating stuff. I'm 27 and have finished university (college in american english), but I still have a hunger to learn and your videos are the perfect way, enteractive and stimulating, less hassle than picking up a book ;) and easier to follow. Thank you for what you're doing, it's an inspiration :)

the thyroid does not make t3. it only makes t4. t4 is converted to t3 in other glands, mainly the liver.

@zatoichi37 the point he is making is that the thyroid does make t3, not that it makes enough to support body function
