DOccipital condyle of skull

Solution

There are 7 cervical vertebrae, $$C_1$$ - $$C_7$$. First cervical vertebrae, i.e., atlas and second cervical vertebrae, i.e., axis, and seventh vertebrae are modified; third through sixth are typical; all contain transverse foramina. Atlas supports head, permits "yes" motion of head at joint between skull and atlas; axis permits "no" motion, i.e., rotation movement at joint between axis and atlas.
