AIIMS 2019 Zoology Skeletal System MCQ Question

Cervical vertebrae are unique among vertebrae due to the presence of transverse foramina, which are openings in the transverse processes that allow for the passage of the vertebral arteries and veins. This anatomical feature is essential for supplying blood to the brain. In contrast, while all vertebrae possess a spinous process (A) and a centrum (B), these structures are not exclusive to cervical vertebrae. The transverse process (C) is also found in other vertebrae but lacks the foramina characteristic of cervical vertebrae.
