Q

Why is the 1st rib is considered to be atypical?

A

It is shorter and wider than the other ribs
It only articulates with the T1 (the corresponding vertebrae)
The superior surface is marked with two grooves, which make way for the sub-clavian artery and vein.
Scalene tubercle seperates the two grooves.
