I Swear, I could kiss you man.
You got me through Immunology as an undergrad and now I'm on my PhD and still watching your videos for guidance. Thank you so much!

An eleven year old video explained to me a better concept that is too detailed, then the newly uploaded ones . Thankyou so much 🐝

Mr. Hasudungan,
I commented a while back in one of your newest videos about how I didn’t like the fact that now you weren’t doing hand drawings. Now, in this 2012 video I see how much effort and quality you have put into your videos. It really touched me to see how you colored that entire big arrow with those thin markers. I haven’t checked out if you have released new videos but regardless of the method, I am grateful for your channel and I really thank you for the time you devote to making these videos.

I once learned an entire semester of calculus from an amazing tutor. Now, Armando, you are doing this again for me in AandP. Thank you for your diligent studying and hard work so you can pass the knowledge on. So grateful

If what this man does doesn't count as charity, I don't know what will. Thank you so much.

[alakkis]

your explanations are 100X better than those in my university

[maggiebalakrishnan]

your video taught me more than my stupid textbook ever dreamed of! i actually said "oh!" multiple times while watching. i love all your videos and i geek out on your art. please keep up the awesomeness!

Hey,
Possibly there is some controversy with this, but what I know, and the sources I use state that pendrin is a IODIDE transporter, and therefore Iodide has to be in the colloid for conversion. It states that "On the lumenal side of the apical membrane Iodide is oxidized"

Love your videos!!! I watch them to help me prepare for practicals and exams, they're perfect for integrating all the information from my textbook. I just wanted to note that T3&T4 are amino acid derived hormones, not lipid. Thanks!!

[Isl-pbvt]

Armando thank you for these classes. I was a second year med student when i started to watch your videos and now i am a resident( soon will be consultant) and still watching you. You are a legend!

[dewaldhart]

Armando, you have been a lifesaver during my first undergrad in Physiology, and now for my second one in Medicine. Thank you for making concepts look so easy and fun. I can literally watch a video of yours once and it sticks :)

[johnborleo]

[triotrio]

[yejikim]

Thank you so much. T3 and T4 were just floating in my head and this is just what I needed!!

[eriwa___]

it been 10years and this video still helps....God bless you man

Very cool, but a few comments.
TRH receptor is coupled to a Gq protein in the tyrotroph cell, and TSH receptor is coupled to a Gs protein in the follicular cell membrane. 
Another detail is that the negative feedback acts directly and indirectly: by directly inhibiting the production of TSH by the tyrotroph and indirectly diminishing the production of TRH receptors on the surface of tyrotroph cells.
Last, but not least, when the iodine attaches to de 5, 3‘, 5‘ carbons or 3, 3‘, 5‘ carbons, it is called “reverseT3“ (rT3) and has no biologic activity, T3 has only biologic activity if the iodine is in the 3 and 5 carbons (regardless if it is attached to 3‘ or 5‘ carbon).

Very useful video, congrats.

[sanak]

I am thanking God for randomly reaching in your channel...no words . it's beyond words...thank you soooo much..just by a single video..I get addicted to your teaching

[hohohohahahah]

Oh armando, i love you for the rest of my medical life 😂
