foliate, circumvallate and fungiform are tongue papillae where taste buds are located, right? they are not the real taste buds. That is one of the misconceptions.

@abigail Gamboa Yeap! Filiform papillae doesn't contain taste buds, but circumvallate and fungiform papillae do!

exactly! each papilla has hundreds of buds which have the receptors

I had the same question.

Thank you!

i love this guy. he's a bumbling mess he sounds like hes tutoring his crush! lol

thank you so much

thanks!

gives a well general overview

Besides opening the ion channels, Doesn't the Gprotein cause PLC to generate something ?

hello khanacademy, i have been a fan of your videos and had had much help while preparing for my boards and entrance examinations. now i am in a reputed medical college and a small part of the credit does go to you. but to see this much misinformation being propagated is very saddening. i would really request whoever doing this video to please read proper books before doing this because people often just watch your videos before an exam and they might be misguided.

The video is clearly not made by an expert rather a person who just googled five minutes before making the video.Taste buds are different from taste papillae and taste receptor cells do not have axons rather they synapse with neurons having axons going to brain. This video according to me is merely jargons for a layman.

Ok so the narrator said that intramembranous g protein, after being dissociated, can do a couple of things. One of them is opening ion channels and he did not talk about the other one right?

the other one, he meant, was the firing of action potential. yeah, it could be stated as one thing. coz its just steps in the same process.

thank you!

But if the salt molecule only activates via ion channels how can it go on a sweet receptor and activate a g protein?

@calebm6818

It doesn't need to. By adding the ion channel, the Na+ from NaCl depolarizes the membrane and effectively stimulates the sweet cell. I think his point was to show that it is the cell and its wiring, and not the type of receptor, that determines flavor perception.

Nice😍🥰😘😘

Nice video, but I think he incorrectly refers to papillae as tastebuds. No?

Axons from the taste cell???? Nooooo

Yes, I thought the taste cells synapse with the sensory afferent neuron?

Goose-tatory.

so much misinformation D:

what? will salt molecule even activate the sweet cells? it's not quite possible naturally, right? only sweet molecules activate the sweet cells.

@calebm6818

3 жыл бұрын

Yes, it isn't possible naturally. I think he meant that a salt molecule can activate the sweet cells IF you add in the ion channels that are activated by the salt molecules.

that's a clear information... can u just give us the references

what about the filiform tastebud

@al-yamantaha9732

Ncebakazi Dlamini filiform rarely has any tastebuds unlike circumvallates or foliates which can have around 3000 and 1500 tastebuds respectively.

what he's describing as taste buds are actually papillae. NOT taste buds.

Sir please tell a little louder.

The taste cells don’t have aksons

Too slow

This guy should be arrested.

Nope, it's an ionic compound. Atoms in molecules are glued together by covalent bonds.

Breathe Leo, basic chemistry doesn't distinguish between electrostatic bonds and covalent ones....but they will qualify that to the non laymen someday in their journey.
