What is 3?
These ribs have a direct attachment to the sternum
What are the Vertebrosternal Ribs/True ribs/ ribs 1-7?

What is a meatus?
A shallow depression in a bone, often serving as a muscle attachment site
What is a fossa?
The name of the vertebrae that allows you to shake your head "no"
What is the axis (C2)?
This triangular bone articulates with the ilium at the sacroiliac joints
What is the sacrum?
The name of the trapezoid-shaped superior structure of the sternum that articulates with the cartilages of the 1st pair of ribs

The middle bone of the sternum that allows for the attachment of ribs 2-7
What is the body?
A hole in the bone for nerves or blood vessels
What is a foramen?
A large, blunt, irregularly shaped projection (only found on the femur)
What is a trochanter?
These parts of the thoracic vertebrae articulate with the ribs
What are the costal facets?
This bone is the terminal end of the vertebral column
What is the coccyx?
The structure connecting ribs to the sternum

The part of the ribs that articulates with the transverse process of a thoracic vertebra
What is the tubercle of the rib?
A small, rounded bump used for muscle attachment
What is a tubercle?
A small air-filled cavity found within certain bones
What is a sinus?
This vertebra lacks a vertebral body
What is the atlas (C1)?
The name for the part that links the transverse processes to the spinous process
This indentation on the body of the sternum serves as the site where the ribs attach via costal cartilage
What are costal notches?
The most inferior bone of the sternum
What is the xiphoid process?
A large, roughened bump for muscle attachment
What is a tuberosity?
The rounded end of a bone, typically part of a joint
What is an epiphysis?
This portion of the vertebra connects the body to the transverse processes
What is the pedicle?
The vertebral column and thoracic cage are two of the three main components of this skeleton division
What is the axial skeleton?
This marks the point of greatest curvature on the rib
What is the angle?
This is the narrow, inferior portion of the sacrum
What is the apex?
