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 C
Explanation
The thumb has three joints: the carpometacarpal (CMC) joint, the metacarpophalangeal (MP) joint, and the interphalangeal (IP) joint.
The CMC joint is a saddle type of joint that allows the thumb to move in multiple directions. A saddle joint has two concave surfaces that fit together like a rider on a horse.
Choice A is incorrect because hinge joints allow only flexion and extension movements, such as the IP joints of the thumb.
Choice B is incorrect because condylar joints have an oval-shaped surface that articulates with a shallow cavity, such as the MP joint of the thumb.
Choice D is incorrect because ball and socket joints have a spherical head that fits into a cup-like socket, such as the shoulder or hip joints.
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.
