• Vertebral foramen is where the spinal cord is located.
• Transverse process is where the parts of the arch that extend from the body of the vertebra to two lateral projections.
• Intervertebral foramen, a hole that allows the spinal nerve to exit from the vertebral column
• Cervical curvature is convex, thoracic curvature is concave, whereas the lumbar curvature is convex and the sacral (pelvic) curvature is concave.
• Scoliosis is lateral curvature, kyphosis is an exaggerated thoracic curvature, and lordosis is exaggerated lumber curvature.
• Atlas (C1) is the only cervical vertebra without the body.
• Axis (C2), it has a unique process called the dens process, which runs superiorly through atlas.
• Vertebra prominens (C7), it has a spinous process that projects sharply in a posterior direction.
• Rib facet is where rib attaches to one vertebra
• Demifacet has a smooth attachment point
• Sacrum is a large, wedge-sharped bone composed of five fused vertebrae.
• lines of fusion are called transverse lines, and can be seen on both anterior and posterior sides.
• Sacral promontory is a rim on anterior superior part of the sacrum, and the ala are two expanded regions of the sacrum.
• Sacral hiatus is the inferior opening of the sacrum
• Coccyx is terminal portion of the vertebral column and usually consists of four fused vertebrae.
• Hyoid is a floating bone at the junction of the floor or the mouth and the neck
• Thoracic cage is made up of the ribs and sternum
• There are 12 pairs of rib
• Angle of the rib (costal angle) is the part of a rib that makes a sharp bend at about the same distance from the midline as the inferior angle of the scapula.
• Sternal end is the one that attaches to a coastal cartilage prior to joining the sternum.
• The first seven pairs of ribs have their own individual costal cartilages; the eighth to tenth pairs share one costal cartilage between them; and the eleventh and twelfth pairs do not have any associated costal cartilages.
• The first 7 pairs of the ribs is called true ribs
• the 8 to 12 pairs of the ribs is called false ribs
• ribs 11 and 12 called floating ribs because they are not attached to the sternum.
• Sternum is composed of three fused bones: Manubrium, body, and xiphoid process
• Manubrium - upper part of the sternum, articulates with clavicles at the sternoclavicular joints
• Body - middle portion of the sternum, articulated with the manubrium superiorly and the xiphoid process inferiorly
• xiphoid process - where the manubrium meets the body of the sternum
• Xiphoid process is a bladelike part that is the most inferior segment of the sternum.
