Cervical vertebrae have which landmark that's not found on any other?
Spinous Process.
Transvers Processes.
Costal Facets.
Transverse Foramina.
The Correct Answer is D
The transverse foramina are openings in the transverse processes of the cervical vertebrae that allow the passage of the vertebral arteries and veins.
They are not found on any other vertebrae.
Choice A is incorrect because spinous processes are bony projections on the posterior aspect of all vertebrae that serve as attachment sites for muscles and ligaments.
Choice B is incorrect because transverse processes are lateral projections on all vertebrae that serve as attachment sites for muscles and ribs.
Choice C is incorrect because costal facets are articular surfaces on the thoracic vertebrae that articulate with the heads of the ribs.
They are found on all thoracic vertebrae except T11 and T123.

Correct Answer is ["Occipital bone"]
Explanation
The occipital bone is a flat, unpaired bone located at the posterior aspect of the skull, forming the lower part of the back of the head.
It features several surface landmarks, including the external occipital protuberance, which serves as an attachment site for muscles and ligaments.
The occipital bone also contains several foramina, including the foramen magnum, which allows the spinal cord to pass through and connect to the brain.
The occipital bone is an important site for the attachment of muscles involved in head movement and posture.
Correct Answer is ["thoracic costal facet"]
Explanation
The thoracic costal facet is a feature found on the thoracic vertebrae, which are the bones that make up the mid-back region of the spine.
The costal facet is a small, flat surface located on the transverse process of the thoracic vertebrae, where it articulates with the head of the rib.
There are two costal facets on each thoracic vertebra, one on the transverse process and one on the body of the vertebra.
The costal facet is an important anatomical feature as it provides stability and support to the rib cage and facilitates the movements of the thoracic spine during respiration and other activities.
Injuries to the costal facet can result in rib fractures or dislocations, which can be very painful and require medical intervention.
