In which type of vertebrae do we find transverse foramen?
Cervical Vertebrae.
Lumbar Vertebrae.
Thoracic Vertebrae.
Sacral vertebrae.
The Correct Answer is A
The cervical vertebrae are the only vertebrae that have transverse foramina, which are openings in the transverse processes that allow the passage of the vertebral arteries and veins.
Choice B is incorrect because lumbar vertebrae do not have transverse foramina.
They have large bodies and short, thick transverse processes that serve as attachment sites for muscles.
Choice C is incorrect because thoracic vertebrae do not have transverse foramina.
They have costal facets on their transverse processes that articulate with the tubercles of the ribs.
Choice D is incorrect because sacral vertebrae do not have transverse foramina.
They are fused together to form the sacrum, which has four pairs of sacral foramina on each side that transmit sacral nerves and vessels.

Correct Answer is ["Foramen transversarium"]
Explanation
The foramen transversarium is a canal that is found in the transverse process of the cervical vertebrae, C1 through C7.
It is an opening in the bone that allows the passage of the vertebral artery, vertebral vein, and sympathetic nerves.
The vertebral artery passes through the foramen transversarium in C1-C6 vertebrae, while the vertebral vein passes through the foramen in C1-C7 vertebrae.
The sympathetic nerves pass through the foramen in C1-C6 vertebrae as well.
Injuries to the foramen transversarium can cause damage to the vertebral artery and vein, leading to a variety of symptoms, including dizziness, headaches, and visual disturbances.
Correct Answer is B
Explanation
The joints between the vertebrae are secondary cartilaginous joints (symphyses) that are formed by the intervertebral discs between the vertebral bodies.
A symphysis is a type of joint that has a fibrocartilaginous disc between two bones that allows slight movement.
Choice A is incorrect because synarthrotic joints are immovable joints, such as the sutures of the skull.
Choice C is incorrect because sutures are fibrous joints that are found only in the skull.
Choice D is incorrect because gomphosis is a type of fibrous joint that anchors a tooth to its socket in the jaw.
