On the perforated acetabulum of dinosaurs

Is the perforated acetabulum actually a defining characteristic of dinosaurs and do anchiornis, microraptor, and scansoriopteryx lack this structure as is claimed in [Feduccia’s study]?(https://www.researchgate.net/profile/Alan-Feduccia/publication/271658034_Jurassic_archosaur_is_a_non-dinosaurian_bird/links/54f3b2b00cf2f9e34f080189/Jurassic-archosaur-is-a-non-dinosaurian-bird.pdf?origin=publication_detail) I’m aware that Feduccia is a crank largely rejected by most paleontologists today but I’m wondering about the details of this study and why they may be wrong.

(What’s up with my post being downvoted simply for asking a question?)

Help! Does my left acetabulum (right in picture) appear to be damaged? For context, I broke my femur when I was 11 and had a rod placed. I’ve had leg pain on/off since, but recently it just keeps getting worse. Went to the orthopedic, Dr. was uncertain about the cause of pain

How to pronounce Acetabulum?

Salve! Let me explain first. I’m a med student and Acetabulum is also an anatomic part of our body besides its usage as bowl. By the way in my country we don’t learn latin in schools. Just because im curious about latin literature I started learning latin in college on my own with Rosetta Stone. The long and the short of it, my anatomy professor pronounced it β€œASSETABULUM” but my Latin language resources pronounce it as β€œAKETABULUM”

Since english is not my main language i hope you understood what i mean as the pronounciations above. Can you help me to choose the correct one?

Eka Pada Sirsasana – hip joint makes a strange sound, femur head may be getting stuck in acetabulum?

Hey everyone. Recently eka pada sirsasana was added to my practice. I don’t have the most open hips in the world so needless to say the posture is bordering on making me regret being alive.

I’ve looked around this sub for some tips and so far they seem to help (prep with reclined pigeon and firelog before eka pada, I already sit in padmasana and or cross legged even on chairs, I try my best to really tap into that external hip rotation in my primary postures, my teacher actually tried to prep me for it by entering from a reclined position but that actually caused me more pain than sitting upright). This week I was actually able to get a leg behind my head (still had to hold it there myself, and couldn’t fold), and I had the energy to attempt and hold there for a few breaths three times per side (which is huge for me since even last week I would attempt once, let go at two breaths, and then kind of writhe on the floor in pain before moving onto backbends). I was absolutely sure that through daily attempts I would manage to enter it in a few months at least, but today I noticed something about my joints and I’m not sure anymore.

Every time I pull my knee back I hear this soft β€œclick” from my acetabulofemoral joint (I think that’s the name). Doesn’t quite sound like a regular joint crack. Kind of feels the head of the femur gets stuck against the β€œsocket”? Like if you were to fasten a seatbelt, that kind of noise. This doesn’t happen just for this posture, it’s actually very frequent but I’ve been dismissing it for a while (just now I switched my position in my chair and the clicking happened again). Also happens if I do those β€œcircles” in the air with my knee, sometimes when I raise my leg for uttita hasta padangustasana or supta padangustasana, if I draw my knee in towards my chest even if I have no hip rotation... I feel no pain when the sound happens (google told me that’s when I should REALLY worry) and usually if I repeat the sound-producing movement right after I won’t hear it again. I’ve tried to look this up but I probably don’t know how to describe it well because I can’t seem to find anything.

I’m now worried that my skeleton simply won’t permit me to ever access this posture, because the femur head is too large (kind of like how some people will never get their knees to the floor in baddha konasana or will never be able to do the frontsplits / samakonasana because the joint traps the femur head too much to allow those movements). I’m really

"Acetabulum" - need clarification on the etymology.

So the acetabulum is a pocket in the coxal (hip) bones where the femur's head (round part) inserts.

Its etymology, taken literally, means "vinegar cup". The "cup" part makes sense due to its round nature, but the "aceta-" prefix leaves me confused. Is there a story behind this name? What am I missing?

SERIOUS: This subreddit needs to understand what a "dad joke" really means.

I don't want to step on anybody's toes here, but the amount of non-dad jokes here in this subreddit really annoys me. First of all, dad jokes CAN be NSFW, it clearly says so in the sub rules. Secondly, it doesn't automatically make it a dad joke if it's from a conversation between you and your child. Most importantly, the jokes that your CHILDREN tell YOU are not dad jokes. The point of a dad joke is that it's so cheesy only a dad who's trying to be funny would make such a joke. That's it. They are stupid plays on words, lame puns and so on. There has to be a clever pun or wordplay for it to be considered a dad joke.

Again, to all the fellow dads, I apologise if I'm sounding too harsh. But I just needed to get it off my chest.

Something to think about.

After listening to several encounter stories, every now and then you hear them speak of a sound that has a resemblance of knuckles cracking, and it’s almost always what alerts the victims of the dog man’s presence. When i first heard of this i was very intrigued and got to speculating. The best conclusion i got to is a second socket the femur head can slip into (this explain the popping sound witnesses hear ) whenever it wants to change from all fours to a biped stance. I really love this detail cause it gives the dog man some credence from eyewitnesses and a biological tone rather than a supernatural origin. This does not mean ghosts or demons don’t exist but things of this subject (dog man, bigfoot, or crawlers) become easier to understand once seen from the natural world.

For context I'm a Refuse Driver (Garbage man) & today I was on food waste. After I'd tipped I was checking the wagon for any defects when I spotted a lone pea balanced on the lifts.
