Question

BlackTom AI · Accepted Answer

Restating the question and options for clarity: Which of the below statements are incorrect when referring to cervical vertebrae?
Option 1: 'There are 10 cervical vertebrae.'
Option 2: 'They all possess transverse foramina'
Option 3: 'Allow a greater degree of mobility than other vertebrae'
Option 4: 'They include the only vertebrae to articulate with the skull.'
Option 5: 'They include two unique vertebrae with their own names, the atlas and axis.'

Analysis of each option:
Option 1: 'There are 10 cervical vertebrae.' This is incorrect because the human cervical spine consists of 7 vertebrae (C1 through C7). The count of 10 would imply a fuller upper spine than anatomically present in the cervical region, which misstates basic vertebral anatomy. A student should flag this as false based on standard vertebral counts.
Option 2: 'They all possess transverse foramina' This statement is generally correct. All cervical vertebrae have transverse foramina in their transverse processes that transmit the vertebral arteries (and veins). While C7’s transverse foramina are smaller, they are typically present, making this a true statement overall.
Option 3: 'Allow a greater degree of mobility than other vertebrae' This is true. The cervical region especially enables substantial range of motion (flexion/extension, lateral bending, and some rotation) compared with thoracic and especially lumbar vertebrae, due to their articulations and unique features like the atlas and axis.
Option 4: 'They include the only vertebrae to articulate with the skull.' This is true because the atlas (C1) articulates with the occipital condyles of the skull, forming the atlanto-occipital joint, enabling nodding movements of the head.
Option 5: 'They include two unique vertebrae with their own names, the atlas and axis.' This is true. C1 is the atlas and C2 is the axis, both having distinctive structures (no vertebral body for C1 and the dens of C2) that set them apart from other vertebrae.

Putting it together, you can see that the only statement that is incorrect is Option 1, while Options 2–5 are correct descriptions of cervical vertebrae.
