Endocrinology | Parathyroid Gland | Calcitonin 

I usually start with these videos that way when I get to class I already understand everything the professor is talking about. Ninja Nerd Science videos usually give me twice as much information in half the time of my professors.

I am not a medical student or pre med... as a genomics scientist I can say that Zach does a terrific job explaining!!! Amazing!

Hey Zach. I'm an mbbs student and today I'm here to wish you a "very very happy teachers' day" man. You certainly are a great teacher and life savior😇. I've my endocrinology test by tomorrow and you're lectures have once again saved from wasting so much extra time on guyton than is needed.

"I like milk too but that's not the point" 😂

That feeling of joy when you finish watching the video and you understand every single thing

I am grateful that you are in RU-vid.

Our whole PA program is watching your vids as a supplement to our lectures. Thanks!

Why can't the people who get all my tuition money teach like this?

You are a true blessing, you managed to teach me about endocrinology in short videos which doesn't add up to 5 hours, in which my lecturers took 4 classes of 2 hours each to teach but i didn't understand much... THANK YOU SO MUCH NINJA NERD

I just wanted to say thank you one more time. I'm a brazilian med student and your classes are so helpful to me. It is amazing to watch and learn with u guys!

Just to clarify: overall net effect of PTH activity is INCREASED blood calcium and REDUCED blood phosphate; VITAMIN D causes INCREASED calcium and INCREASED phosphate. This makes sense if you remember that responding to LOW CALCIUM is the key here - the systems are not trying primarily to alter blood phosphate (which is generally much less clinically concerning at abnormal levels). Excellent lecture!

MBBS student, I've got endocrinology exam tomorrow, you've made me understand everything 😭❤️

I could never quite understand this topic until this video. Thank you so much, your lectures are absolute gold!

As someone who had primary hyperparathyroidism (adenoma on LR parathyroid), I really appreciate this. I wish gen practitioners knew more about parathyroid problems.

Can’t describe how amazing is you lessons.. I never get bored of them 😍😍

I like those videos (like Dr Najeeb's for example), where you can relax and get knowledge with clear explanation where you don't have to rack your brains to understand.. Well done!!

I watched lots of videos - including my uni lectures - to understand the relationship between calcitonin, V D, and the PTH, and finally, I understood it with this video. Thanks a lot man.

As you teach incredibly … i just wanna meet you once in my lifetime … thankyou sir for your such efforts that are making my journey to be a doctor easier and easier💯

You are my LIFESAVER!!!!!!!! I adore you

Ninja nerd science - I adore you!!! All of your videos are immense...so informative and interesting. THANK YOU :D

I am preparing for Canadian Dental Boards exam and bro u really made it easier to understand and ingrain this stuff in brain . Thanks a lotttt

My mother just had a high PTH level. So looking forward to this video to learn more.

Ninja Nerd videos are my go to when I dont understand any concept. They always give the appropriate depth of information in a way that I can really remember it.

Yes Ninja nerd you are helping us. Pls make more videos. Thank you for your excellent work .

Sir!!! God bless you, infact I'm more thankful that you decided to open a RU-vid channel to educate us, thank you soooo much sir. I'm really excited, you explained this perfectly 🥺❤️

Thank you so much!! My teachers are using your videos for the course and I'm not sad about it

You are a great teacher. Your ways of explaining are far better than those of lecturers of my med school

This channel had saved me. I hope there will MICRCOBIOLOGY AND PARASITOLOGY lecture vids avail soon. More power to this channel!

This was an amazing overview and answered so many questions. Thank you.

Somehow it seems inadequate to just say THANK YOU for this incredible lecture on a subject that is of paramount importance to me. I have been diagnosed with hyperparathyroidism. My doctors gave me an overall view of what the diagnosis entails, and I did some research online, but I didn't really understand the process until I found your lecture. It is so amazing that such a tiny gland has such a responsible job to do! It is also amazing that the malfunctioning of the gland can have such an impact on the whole body and interfere with my energy level, control of my body temperature, mood swings, etc... Again, THANKS A MILLION for sharing your knowledge with us. I feel a lot more confident now that I know the process. I can only hope that when they do the surgery they will find that just one of the parathyroids needs to be taken out. Would hate to face the rest of my life without their help! :)

Wt a lecture sir, a mind opening lecture of my life as per my endo studie.May God bless u sir...

Hi Zach. I think you do a wonderful job explaining. You break it down so that it is easily understood. I am going back to be a nurse practitioner and have watched many videos of yours. You are an awesome teacher. Thank you.

It is the first time I find this topic interesting.. Thank you ninja sir 🙋

Wow, that was powerful discussion! Thank you. You deserved 100percent applause!!!

one of the best lectures i have heard. thank you so much

Hey it is of great pleasure to inform you that I passed my exams because of your videos, keep up the good work and God bless you, thank you very much.

“PTH ready to FRICK THINGS UP” 😂

I hope you always stay blessed, healthy and gets wealthy but still be the wonderful teacher that you are. Ma shaa Allah !

This is so much better than powerpoint presentations in schools.

you are one of the best teachersi ve ever watched may god bless u

Prof, you are unique to me, and i have a heartfelt thanks to you. I hope long live to you 🙏🙏🙏

If my professor explained this, it was not possible to understand. If Zach explain things it's so easy to get it. Thank you. :D

I've learned so much since I started to watch your video lessons, you're a genius!! Thanks again!

I have a business background and extremely curious mind and I must say you're making me go to med school for how clearly you explained everything! Makes sense to prepare ourselves prior to going to a doctor and these videos help a lot! Thanks

lmao when he pulled out the secret board, what a flex. love all your lectures (and your sense of humor that makes them more engaging!) 💞

Thank you very much Zach. You are the best. I spend less time poring through textbooks before I understand. God will bless you
