The mitochondria is the powerhouse of the cell.

 

[deleted407021]

Our brains think about themselves.

Dank meme bro. 10/10 would generate ATP again

I'd answer, but I'd have to get pretty deep into neurobiology, and it'd probably be over your head.

ayyy lmao

 

[bunchesonothing]

Not the coolest, but something that often makes people go... "woah"... is that the inside of the gastrointestinal tube is technically considered to be the outside of your body.

On a more serious note, I remember being pretty mind blown in biochem reading about how when you're starving, you exhale acetone (its a byproduct of ketone metabolism or something? idk).
I really wanted to find an anorexic person to see if they could remove their nail polish with their breath.

 

[7331poas]

I mean. At the microscopic level, all the biochemistry we know and the organic mechanisms about them.

Doesn't it blow your minds that we moved from the original theory of the carbocation all the way to the point we are at now.

There are more bacterial cells in your body than human cells.

I had to google that - I remind you of Einstein with a unibrow?

The most fascinating thing about the human body, for reals, is that multicellular life is even a thing. It's like, communism at the cellular level. That different cells got together, and one was like, "I'm going to do the thinky bits," another was like, "I'll just contract and relax for all eternity," and another was all, "I'll form the anus!" is just astounding, evolutionarily. Like, it's just incredible how multicellular life and specialization happened. That and mitochondria- I'm glad we became friends with those little guys.

Oh, and I really love the development of the cardiovascular system- simple hearts to two chambers to three and finally four. Amazingly cool. Humans though, we're just kind of animals like any other and not all that interesting on our own. Evolution is really what makes the human body amazing to me, just the intricacies of it.

I know right! Everytime I think about how complex we are, I feel more and more like we shouldn't even exist. Like holy ****

Metabolism is cool. Cancer Metabolism is cooler

A single Purkinje neuron looks like this....

 

[alpinism]

That ATP is needed for muscle relaxation, hence rigor mortis after death.

The fact that ischemic heart muscle creates injury currents leading to ST segment changes is also pretty cool.

I had to comment just so to show my pic. So, here it is lol.

Btw, it is an absolutely amazing show (assuming your sense of humor aligns with that of the show's)!

Already had to

The thing that always tripped me out was the fact that your vision is generated just by the bipolar cells of the retina having a high RMP. Since your rods and cones are essentially just on/off switches for the bipolar cells, are we really seeing? Or is it all just a figment of our minds? Bruh...

 

[NotWayneBrady]

... and then I think about the human knee, and all I can think is "what the hell, evolution."

Once you start getting into human perception everything gets weird.

The heart can beat by itself. Take it out of the body and it still beats, for a while.

Oh and every time I pee, I just look and think "man, this all used to be my blood"

 

[What is up doc?]

That a single human rib can transform into an adult woman. This has only been shown in vitro tho

Given the advances in cloning technology, not even a whole rib is needed these days.

[Astra]

I think the reason that hungry people have bad breath is the build up of acid from bacteria on their teeth.

I think the coolest thing is how quantum physics governs cellular processes. Like quantum tunneling in enzymatic activities, or proton tunneling as a mechanism for DNA mutation. Someday, maybe our grandkids will have to take quantum biology in medical school.

Or outside of humans, how quantum entanglement may play a role in bird migration. Crazy.

Ventricular escape rhythm

 

[Munty]

I really like this thread.

I took a class just on sensation and perception and I just loved how visual receptive fields work and how they lead up to specific neurons (such as the grandmother cell) that respond to VERY specific stimuli.

Or how incoming sounds are analyzed for the inter-aural time and level differences to determine the location a sound is coming from.

That whole class was pretty cool.

Not related to humans, but when I first started doing microscopic analysis in my research I just sat there in amazement watching plant cell cytoplasmic streaming moving around the chloroplasts in live cells.

V(D)J recombination in developing B cells is ridiculous.

Or cancer, which is basically capitalism- the strongest cells prosper while the remainder of the organism is sucked dry.

 

[yeasureyoubetcha]

Does that mean Bernie Sanders is the cure for cancer!?

Oh god I hope not! You'll get 1/2 the cure

Cancer, unlike many parasites, doesn't care if the host dies - they are some of the most elegant, greedy and arrogant cells ever.

That's why DKA patients have fruity-smelling breath!

How one carbon atom and a couple of hydrogen atoms can be the difference between a good time and being blind. Illustrates the incredible specificity between substrates.

Hence capitalism- consume and acquire like you're going to live forever, and screw everything and everyone else.
