How many cervical thoracic and lumbar vertebrae are there?
Absolutely! They have features unique to the region they are found in, relating to structure and therefore function. Typical cervical vertebrae (C3-C6) usually have bifid spinous processes which point slightly inferiorly. The spinous processes on lumbar vertebrae are oblong in shape and point directly posteriorly. The articular facets of cervical vertebrae face superior-inferiorly, whereas lumbar articular facets face medial-laterally. Cervical vertebrae have transverse foramen on right and left(containing the vertebral arteries), lumbar have none. They have mamillary processes on their superior articular processes. The bodies of lumbar vertebra are larger and thicker than cervical vertebrae, though they are oval/kidney shaped shaped in both regions. The transverse processes of lumbar vertebrae are much longer, for muscle attachment. Cervical vertebrae have anterior and posterior tubercles extending from their transverse processes. The pedicles of lumbar vertebrae are slightly longer and more defined than those of cervical vertebrae. I think that covers everything, let me know if you think of anything else!
How many cervical vertebrae are there in a normal adult?

Which bony foramen does the internal carotid artery run through?
The carotid canal. When viewed from a superior angle, the internal carotid may appear to be transmitted through the foramen lacerum; however, it is not. The foramen lucerum is actually covered by connective tissue and transmits NO vessels or nerves. Though there are many hypotheses as to the purpose of the foramen lucerum, there is no definitive answer.
