Axial Skeleton
Sternum
Breastbone
Sternum manubrium
Broad upper part of the sternum
Vertebral foramen
Opening in the middle of the vertebra
Anterior arch
Part of atlas that articulates with dens of axis.
Dens of axis
Peglike process that extends superiorly from the body
Spinous process
A bony projection off the posterior (back) of each vertebra
Transverse process
A small bony projection off the right and left side of each vertebrae
Vertebral pedicle
A stub of bone that connects the lamina to the vertebral body to form the vertebral arch
Transverse costal facet
Articular surfaces for synovial joints with the ribs.
Atlas cervical vertebrae
C1, ringlike structure with a short anterior arch and long posterior arch
Axis cervical vertebrae
C2
Cervical vertebrae
Consists of seven vertebrae (bones) that make up the portion of the spinal column located in the neck
Vertebral lamina
Flattened posterior portion of the vertebral arch
Lumbar vertebrae
L1-L5, located in the lower back between the thorax and pelvis
Sternum body
Largest part of the sternum, connects to the ribs via cartilage and forms front of the rib cage, helping to protect the heart and lungs
Vertebrosternal ribs
Ribs 1-7, costal cartilages are directly attached to the sternum
Floating ribs
Ribs 11-12, they have no connection to the sternum
Vertebrochondral ribs
Ribs 8-10, these ribs have indirect attachment to the sternum
Sacrum
Shield-shaped bony structure that is located at the base of the lumbar vertebrae and is connected to the pelvis
Sternum xiphoid process
Smallest part of the sternum that is attached to the inferior end of the body
Thoracic vertebrae
T1-T12, forms vertebral spine in the upper trunk
Coccyx
Tailbone
Transverse foramen
The openings on the transverse processes of all cervical vertebrae
Hyoid
a U-shaped bone in the neck that supports the tongue
