You may have heard that humans and giraffes have the same number of neck bones. And that's true! But it isn't the whole story. See, all mammal species except for three have exactly seven cervical vert
I had a friend in highschool with 9. Just a weird random family trait. I think she said there are only a couple people in the world with it and most of them were in her family.
There may be a benefit for the giraffes to only having 7 neck vertebra in that it make give it more stability rather than having to counterbalance for more joints.
I wonder how many different skeletal abnormalities there are for humans that may go completely unnoticed or result in no difference in quality of life, such as a cervical rib or Adele’s extra vertebra
Okay immediate extra points for referring to birds as reptiles. It is so overdue that we start consistently doing that I love you guys keep doing it thank you thank you thank you!
I have an extra lumbar vertebra. The one that's supposed to fuse to the pelvis didn’t, and the sides of it are different from each other. One side has the proper locking joint for that region, but the other side has the kind of joint found on the upper back.
I get why they called it that, but it's still confusing that where you get cervical cancer is so far from your cervical vertebrae. (the cervix being the "neck" of the uterus. According to etymology online, the neck meaning is older)
I considered skipping this one (the title does not contain new information to me) but it was fascinating, especially the correlation between cancer and cervical ribs!
We have the same number of vertebrae as giraffes? That seems like a stretch.
