In the cervical spine which SP is least prominent?

• A. C2
• B. C7
• C. C3
• D. C5

Answer: (C)

In the cervical spine, spinous processes are generally short and often bifid, so they’re not very prominent except at certain levels. The seventh cervical vertebra has a long, nonbifid spinous process that sticks out prominently (vertebra prominens). Among the remaining cervical levels, the third cervical vertebra typically has the smallest, least prominent spinous process. Therefore, the spinous process of the third cervical vertebra is the least prominent.
