Some people are born with extra ribs called cervical ribs which grow from the C7 vertebrae in the neck. It’s a weird and rare mutation that a lot of people don’t even know they have, although it is also a cause of thoracic outlet syndrome, which is where pressure is applied to the nerves, veins, and arteries running into the arms. It can be really painful, and in some rare cases can cause gangrene in the arms. If left untreated it can kill you if you’re really unlucky. (source: I have the non-cervical rib induced variety).
