You can check by putting your thumb and ring finger pinky together and flexing your wrist towards your thumb and “inward”, the tendons should be visible on your wrist if you have it.
You can have 0, 1 or in rare cases 2 on each arm and it can be different on each arm.
I saw a cadaver with 4, most people have from 0 to 2.
I see how you got tripped up though, your palmaris longus is a little indistinct and your carpi radialis is very distinct so it looks very similar and I didn’t explain it as clearly as I could. (Your palmaris longus is the one that’s more towards your pinky btw)
Try making a fist and flexing your wrist as much as you can , the difference should be a bit clearer. The palmaris longus goes over the flexor retinaculum (kind of like the wristwatch areaom the inside of your hand) all the way, while the flexor carpi radialis goes deep and shouldn’t stand out as much. (Try flexing only plantarly and not in the thumb direction if the difference still isn’t clear)
Thats pretty rare. I think its like 2% of people or something like that.
A teacher told me they used to use creases for operative landmarks and surgeons would be worried by people with sydney and simian creases, but they stopped doing that because it turns out the creases don’t correlate to shit.
yeah, i dont know about any genetic abormalities i may have. my dad did kinda have 4-ish kidneys (or maybe just 2 but with more than the required amount of piping) though, we know that. nobody knew until he was 50+ cos nobody looked
where my tongue-curling attached-earlobe havers? we must rise up and overcome our inferiors with our god-like powers!
How many palmaris longus muscles do you have?

GET OUT
Pretty sure 2 both sides
My anatomy professor would like your phone number and I am not kidding.
One. The other one is the flexor carpi radialis.

Aha, yeah, I’m a biologist not a human anatomist. H. sapiens is the least interesting animal imo;)
NO! the superior people are those with one palmar crease in at least one palm!
You’ve got a simian crease?
yeah, on my right hand
