Reply to comment by dfgdfgadf4444 in When people can’t walk it means they have broken neural pathways. Then why can’t you just connect them? by CuteAlexaL
Of course! This is something I’m mostly familiar with from the popular press, so I’ll leave it to someone else to dig up the more technical papers but:
Here’s an article in Science about recent projects and results.
Here’s a more technical article from Nature Medicine from the research team that pioneered this technique
Here’s a human interest story from a hospital network that performed one of these operations which gives a look at what this is like for a patient.

The structure of red meat makes it very difficult for bacteria to penetrate below the surface, which is why you can eat a steak rare as long as the outside gets cooked.
I dont believe poultry meat has the same "impenetrable" properties, so I don't think you can process it in a way that could be safe rare.

I think that's the rationale behind putting it in the cheek (i.e. between the teeth and the lips), and of using a gel instead of a less viscous liquid like a juice: to minimize the risk of aspirating it.
At least one first aid instructor I've had has suggested running the gel into the flesh of the lips and gums, which should reduce that risk even further, but I don't think that was ever a formal part of the training.

There are 12 cranial nerves (basically nerves that come directly out of the brain, not through the spinal cord).
Some of them receive signals only ("somatosensory", S). Some of them send signals only (motor, M) and some do both (B).

There's also the wrist bones one, "Some Lovers Try Positions That They Can't Handle" but I don't remember what they all stand for anymore, haha.

Wait you googled SA node and you still think you're not wrong?
Damn, dude.
The brain controls the SA node, but the SA node can function without the brain. There's also a ventricular pacemaker. There's backups to the backups. The heart is an important organ.

You’re right the ANS can influence heart rate but the heart itself has an intrinsic rate. The SA node has an intrinsic rate between 60-100bpm. The AV nice has an intrinsic rate of about 40-60bpm. The ventricles have an intrinsic rate of about 30bpm. That’s why in complete heart block often the heart rate is about 30bpm as that’s the default rate of the ventricles when signals from the SA or AV node are blocked.

I don't think about ant guts when chewing on chocolate covered giant ants.

It's worth pointing out that Jonathan is still the oldest verified living tortoise disregarding the estimated birth date, because there are solid records of him being transferred in 1882. So he's verified over 161 years old, just not verified for his full estimated 191.
Finding a tortoise with a verified birth date is going to severely limit your options for how old they might be; even the oldest humans alive today are "unverified" because they predate birth certificates. The oldest tortoise with a verified birth date is likely less than 90, and thus very difficult to find on "oldest" lists, just because we didn't start verifying births long enough ago.

Hmmm I think I would be wary putting something in the mouth of someone who is completely unconscious as they have a high risk of aspirating because they lose their protective airway reflexes.
But by all means if someone has reduced consciousness but they’re still able to swallow then we essentially use exactly that in the hospital context: a sugary gel as first line treatment of hypoglycaemia.

Like it doesnt have organs and liquid and its meal inside it?

It lives in a very specific part of your intestines where other microbiota keep its growth in check and under control. Other places, like the small intestine, don't have that protection. If your large intestine gets perforated and the bacteria can escape directly into your bloodstream, you can develop sepsis and die pretty quickly.

>Is that still taught?
Unless things have changed in the past year or so, since I last took a course.
>Call 911 or a trusted family member/spouse of the effected person.
Yes, if someone is in obvious enough distress that you're concerned about either hyperglycemia or hypoglycemia, you're going to want to get help to them. I should have mentioned that.
>Typically a glucometer is gonna be right next to the insulin or in a diabetics medical supplies.
Sure, but as a first aider, you're not typically trained to use it. I mean, it's not rocket science, but (IANAL, just someone who has taken a lot of first aid courses) Good Samaritan laws only tend to protect you within the scope of your training, and for anything you do outside of that training (like taking even a tiny blood sample), you can be held liable for if things go wrong.
Of course, if the 911 operator instructs you to, that's fine (at that point, you're acting under their authority, rather than your own as a first aider), but it's not something I'd recommend taking initiative on.
>If they are unconscious, don't try to put food or water in their mouth.
I was taught this is the only exception to that rule; a small amount of sugary gel (e.g. honey or icing), deposited in the cheek.
