Question

identify the articulation site that allows us to rotate our head, e.g. shaking the head
o\.○ atlas - axis○ axis - $c_3$○ occipital bone - axis○ occipital bone - atlaspart e (5 of 6)identify the region of the skull that articulates with the atlas.○ foramen magnum○ occipital condyles○ superior articular facets○ mastoid processes

Explanation:

For the first question: The pivot joint between the atlas (C1) and axis (C2) enables rotational head movement like shaking "no". Other listed joints do not produce this specific motion.
For the second question: The occipital condyles, rounded projections on the occipital bone of the skull, form a joint with the atlas (C1). The foramen magnum is an opening, superior articular facets are on the atlas, and mastoid processes are for muscle attachment, not articulation with the atlas.

Answer:

1. Atlas - axis
2. Occipital condyles
