Cervical Ribs

[Orleander]

This person has 2 extra ribs, called cervical ribs. Which ones are they???

Opera singer Maria Field is hoping to turn professional after surgeons discovered and removed two extra ribs

I would guess the top two that look a little smaller. They would attach to the cervical vertebrae, which are at the top of the spine.

Thanks Idle.
Is it a genetic quirk, or is it something we may have all had at one time?

 

[Idle Mind]

Probably more of a quirk with how the fetus developed and how the particular gene(s) responsible for growing ribs was expressed. Perhaps similar to the people with polydactyly in that other thread you started.

so it could be inheiritable.
