Shh is expressed in the most posterior location of the limb bud and works in concert with FGF signaling. If Shh were lost or inhibited in a late developing embryo after limb bud formation has been initiated, what structures would still form? a) Only middle structures such as the radius and ulna b) Only proximal and middle structures such as the humerus, radius, and ulna c) Only proximal structures such as the metacarpals and phalanges d) Only distal structures such as the metacarpals and phalanges e) Only middle structures such as the humerus f) None of the above g) All of the above
