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 ["Mandible protraction of the temporomandibular joint (TMJ)."]
Explanation
Mandible protraction refers to the movement of the lower jaw (mandible) forwards, away from its rest position.
This movement is also known as jaw thrust.
The joint involved in mandible protraction is the temporomandibular joint (TMJ), which is a synovial joint that connects the mandible to the temporal bone of the skull.
This joint allows for a variety of movements, including:
Mandible retraction: This refers to the movement of the lower jaw backward, towards the skull.
Mandible elevation: This refers to the movement of the lower jaw upwards, towards the upper jaw.
Mandible depression: This refers to the movement of the lower jaw downwards, away from the upper jaw.
Mandible lateral excursion: This refers to the movement of the lower jaw to either the left or the right.
Mandible medial excursion: This refers to the movement of the lower jaw back to its midline position after a lateral excursion.
These movements of the TMJ are essential for functions such as chewing, speaking, and swallowing.
However, excessive or repetitive movements of the jaw can lead to TMJ disorders, which can cause pain, clicking, popping, or locking of the jaw.
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.
