What direction do the cranial facets in the cervical spine face?

• A. Cranial-Caudal
• B. L-M
• C. Caudal - Cranial
• D. V-D

Answer: (D)

The cranial facets are oriented along the ventral–dorsal axis. In the cervical spine, these articular surfaces face toward the front (ventral) and back (dorsal) rather than strictly toward the head/tail or side-to-side. This ventral–dorsal orientation helps create the cervical joints that allow substantial neck flexion and extension, with a degree of rotation, while keeping the joints aligned to limit sideways shear. In contrast, directions like cranial–caudal or left–right don’t describe the plane in which these facets predominantly face.
