Answer to Question 1

Jefferson's

Rationale: The Jefferson's fracture involves fracture to both the anterior and posterior arches of C1.

Answer to Question 2

the mandibular condyles are projected anterior to the petrous pyramids

Rationale: Correct hyperextension of the head and neck for the SMV will be evidenced by the mandibular condyles lying anterior to the mandibular condyles. When the mandibular condyles lie within the petrous pyramids, this indicates the head was not hyperextended enough.
