What is a spine?
These vertebrae have transverse foramen
What are the Cervical Vertebrae (C3-C7)?
These ribs connect via cartilage but not directly to the sternum
What are the vertebrochondral ribs/ribs 8-10/false ribs?
The largest of these openings in the skull allows the spinal cord to exit the cranial cavity
What is a foramen?

What is a condyle?
This portion of the vertebra connects the body to the transverse processes
What is the pedicle?
The number of articulation points between a floating rib and the vertebral column
What is 1?
These projections of a vertebra act like puzzle pieces, locking one vertebra to the next at the facet joints and guiding permitted movements of the spine
What are articular processes?
This broad, superior surface of the sacrum articulates with L5, transferring the weight of the spine into the pelvis
What is the base of the sacrum?
The sweeping lower edge of the rib cage you can feel, created by the false ribs
What is the costal margin?
