spinous process

Explanation:

Identify anatomical landmarks on C1 (Atlas) and C2 (Axis)

• Label 9: Points to the transverse foramen (the opening in the transverse process of both C1 and C2).
• Label 10: Points to the superior articular facet/process (the smooth flat surfaces on top of C1 and C2).
• Label 11: Points to the dens/odontoid process (the prominent upward projection unique to C2).
• Label 12: Points to the spinous process (the posterior projection, visible on C2).
• Label 13: Points to the vertebral foramen (the large central opening for the spinal cord in both vertebrae).

Match labels with the provided options

• 9: Transverse foramen
• 10: Superior articular facet/process
• 11: Dens/odontoid process
• 12: Spinous process
• 13: Vertebral foramen

Answer:

No.	Answer
10	Superior articular facet/process
11	Dens/odontoid process
12	Spinous process
13	Vertebral foramen
