In what type of fracture do we consider the bone to be shattered?
Transverse.
Spiral.
Comminuted.
Greenstick.
The Correct Answer is C
Choice A is incorrect because transverse fractures are the type of fractures where the bone has a horizontal fracture line.
They are usually caused by a strong force applied at a right angle to the bone shaft.
Choice B is incorrect because spiral fractures are the type of fractures where the bone has an angled fracture line that curves around the bone shaft.
They are usually caused by a twisting force applied to the bone.
Choice D is incorrect because greenstick fractures are the type of fractures where the bone is bent and partially broken on one side.
They are usually seen in children whose bones are softer and more flexible than adults.

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 ["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.
