Postganglionic Fibers Puns

Hello to all.

Studied a lot biology on my own. Just have a few questions. Someone with the relevant knowledge will probably find it easy to solve these puzzles for me. So... could you please explain to me:

1. The difference in the above terms.
2. Is it true that a nerve consists only of axons? (same as white matter) If this is the case how axon-to-axon communication works?
3. There's a lot of mixing between the terms neuron/nerve. Sympathetic nerves activate organs during the fight-or-flight response. These nerves are the pre/postganglionic fibers? If this is the case these nerves have only one long axon?
4. Does neuron-to-neuron communication exist outside the brain? Like a chain of neurons from axon terminal to dendrites etc? Without forming a nerve necessarily... the same way a sensory neurons pick signals from the skin.
5. Where do 86 billion neurons exist if the whole sympathetic system works with just a bunch?

Why is it that these fibers are always unmyelinated? Why would any fiber be unmyelinated when it means it would conduct impulses much more slowly..?

Edit: also the majority of perifferal sensory fibers..

Ok I am curious why the sympathetic chain which would benefit from having a faster signal, have unmyleinated fibers for the majority of the fiber? The sympathetic preganglionic is short right and then the postganglionic fiber is long so wouldn't it be better to have myleinated axons so the signal could travel faster?

In retrospect, after S05E16, "Dr. Julian Bashir, I Presume", do you consider this to be an intentional error, designed to hide the truth about himself, or was this a genuine mistake? Later episodes suggest this isn't the kind of mistake he'd make, but since this could have cost him his desired post on DS9 (S03E22, Explorers) I'm wondering what you guys think.

Here's the episode description from Netflix: "Sisko returns from a trip to Bajor with the blueprint for an ancient space vessel that operates like a sailboat, using solar pressure for propulsion."

Sounds pretty harmless, right? Like a filler episode?

Well, it is, in a sense. Nothing all that consequential happens in the episode. Bashir sees an old classmate that he's jealous of, Jake gets accepted to a school on Earth, and Commander Sisko gets motivated about building an ancient ship.

Let's go through all of those and talk about how they connect with the title of the post.

• Bashir sees an old classmate that he's jealous of.

  • Aside from confusing a preganglionic fiber for a postganglionic nerve (rookie mistake!), Julian was the #1 student in his class. Now he's been ignored by the girl that effectively dethroned him, something he's clearly uncomfortable with. He spends the entire episode talking about how terrible she is, or worrying about how she'll react when they speak. When they do finally speak, they clearly become fast friends. She didn't recognize him because she thought he was Andorian, and was a fan of his work.
  • I recently read that most Star Trek villains are just regular people "having a bad day" and that they cease to be villains once you understand them better. Obviously that's not always the case, but most enemies in Star Trek are not truly evil. Even The Borg aren't beings of pure hate. Bashir creates an antagonist for himself, which turns into a friend just as soon as he speaks to them and gets to know them better. That's the core of a Trek antagonist.

• Jake gets accepted to a school on Earth.

  • The conversations that happen aboard the ancient Bajoran vessel between Jake and Benjamin are SO Star Trek and SO Federation. In The Federation, everyone is encouraged to be their best self. It's a lot easier to "be your best self" when the governments of the world have merged, and most societal problems are solved. Many fans see joining Starfleet as the ultimate example of a Federation citizen being their best self, and although that may ring true for a lot of like minded people, there are a lot out there like Jake who aren't interested. Although Jake chooses to stay home at first to be with his father, he later chooses to stay home for at least an extra year in order to stay onboard DS9 and experience all that the "frontier", as Bashir calls it, has to offer. If that's not Star Trek, I don't know what is.

Go post NSFW jokes somewhere else. If I can't tell my kids this joke, then it is not a DAD JOKE.

If you feel it's appropriate to share NSFW jokes with your kids, that's on you. But a real, true dad joke should work for anyone's kid.

Mods... If you exist... Please, stop this madness. Rule #6 should simply not allow NSFW or (wtf) NSFL tags. Also, remember that MINORS browse this subreddit too? Why put that in rule #6, then allow NSFW???

Please consider changing rule #6. I love this sub, but the recent influx of NSFW tagged posts that get all the upvotes, just seem wrong when there are good solid DAD jokes being overlooked because of them.

Thank you,

A Dad.

So far nobody has given me a straight answer

I am currently in the hospital. I had a back operation yesterday. The surgical nurse came in my room and started asking questions about my back. She asked me if I had any falls during the last year. I responded just one. It was after summer.

She laughed and said in 20 years of doing this she never was told that joke.

..... Will get a reward.

Because they work on many levels

Well, toucan play at that game.

Argon does not react.

'Eye-do'

This is my first post pls don't kill me lol.

The people in the comment section is why I love this subreddit!!

Cred once again my sis wants credit lol

Keep in mind, my son is 4 years old, so everything is an original to him.

I had to work late into the evening yesterday, and he was just going to bed when I got home. I had left home for the office nearly 14 hours prior, had a long day, lots of meetings, traffic, etc.

When I walked through the door, I was exhausted, run down, and starving. My wife hugged me and asked how my day was, and I replied, "Done. It was a good day, but has got me exhausted. I just want to grab a bite and go to bed. I'm hungry."

From my son's bedroom, I hear him shout, "Hi Hungry! Nice to meet you!"

Not only did it make me laugh, but I completely forgot about how hungry and tired I was. I went to his bedroom, and we laughed together about it. It was exactly what I needed.

Edit: Thanks for all the awards, kind strangers! I'll let my son know y'all enjoyed his joke too!

I heard parents named their children lance a lot.

He should have a good vowel movement. His next diaper change could spell disaster though.
