Gap junctions are for animal cells, for plant cells we use the term plasmodesmata.

If this is a short distance.... A Short. Distance. Short. Distance... A short distance. If this is a short. Distance.....

Extracellular signal molecules communicate through: 1. Direct contact signalling 2. Paracrine signalling 3. Synaptic signalling 4. Endocrine signalling 5. Autocrine signalling

I use Khan Acadamys videos so much to support my training to be a nurse in Finland and I have to say that, this lecturer make me get things so much better than enyone else. He´s voice and way of speaking and also the sound cuality makes me motivated. it´s in the details. It is how he uses his tone to point out certain things. He´s a natural and I am a fan for sure.

Khan Academy thank you for helping me through my entire freshmen year (:

This channel saves my life

where my AP bio kids at? :)

Plasmodesmata is a type of communicating juction while gap junction is also a type of communicating juction but it is found in nervous tissues and heart so don't get be confused with gap junction and plasmodesmata as told in this video

Khan Academy! Thank you for provide helpful videos!!

thanks ...this will helped with my cytology exam tomorrow

I think the cells can communicate with each other without gaps through the glycoproteins and glycolipids which act as receptor molecules to link two cells but it's not the protein itself

Missed you! God, i love your videos!

شكرا على الترجمة نفهم دروس thank you Doctor

Thank you very much for your great presentation

very good video that is very informative. Thank you so much

This was very helpful

For Voice-A Grade and thanx for teaching

At 0:28 you say plants have gap junctions but I think you mean animal cells have gap junctions and plants have plasmodesmata :)

what programe do you use to do this drawings? i would have much more fun studying if i could draw what im studying on my computer too

Thank you Sal so much!!

I'm from Egypt so I'm not strong enough in English if it is useful to attend you translate the Arabic language better because you are a great service and people of the Arabs are so much Bstffoa Thank you

why does the molecules of Autocrine would even get out in the first place if it would also go back to its own???

hello! thank you very much for your videos, they really help me a lot!! i just have a request if you could please write on a white screen instead of a black one because i would like to print images of the videos and the black screen just makes it harder to print. ill appreciate it if its possible. and again thank you very much

Who is this speaking?, I would like to find some more of his videos, very easy on the ear :)

is this close to the mode in which cell communicate and intergrate during homeostasis?

I’m doing a presentation for this. I hate eighth grade smh.
