Okay, not all the videos can be bangers! 😂
🖐️ You might actually be missing a muscle… and that’s completely normal.
Try this: Touch your thumb to your pinky and slightly flex your wrist.
See that tendon pop up in the middle of your wrist? That’s your palmaris longus.
Don’t see it? You may be one of the people who simply doesn’t have one. 👀
The palmaris longus is considered a vestigial muscle—meaning it likely played a bigger role for our ancestors, but has become less important as humans evolved.
And the cool part? You can function perfectly well without it.
Human anatomy isn’t identical from person to person. Sometimes, normal has variations.
Try it yourself 👇
