Chapter 18 Ribs
A rib x-ray usually consist of what projections
AP or PA and obilique projections
Ribs 8 to 12 are called
False Ribs, because they do not completely surround the thorax.
How long are the anterior end of each rib
Approximatley 3 to 4 inches inferior to its posterior end.
The manubrium's xiphoid is located
In the distal tip of the manubrium and is also a usful positioning landmark. In childhood the xiphoid process is formed only of cartilage; it ossifies in adulthood.
The ribs are attached where
They are attached posteriorly to the thoracis vertebrae, forming the costovertebral articulations.
What kind of bones are the ribs
They are long, flat, slender, curved bones and most have costal cartilage at their anterior ends.
Ribs 1 to 7 are called
True Ribs, they attach anteriorly to the sternum forming cartilaginous amphiarthrodial joints.
If the area of interest is primarily posterior which projection would you use
AP, for greater detail of the posterior ribs
The connection between the rib and its associated cartilage is called
Costochondreal articulation.
Ribs 8, 9 and 10 are attached how
Attached to bands of costal cartilage that attache to the sternum.
Lower ribs are below the
Diaphragm
Upper ribs are above the
Diaphragm
Ribs 11 and 12 are also called
Floating Ribs, They have no cartilage and are not attached anteriorly.
The manubrium's body is located
In the middle portion of the sternum, it is long.
The Manubrium is located
In the superior portion of the sternum
If the area of interest is primarily anterior which projection would you use
PA, for greater detail of the anterior ribs
Another name for breastbone
Sternum
The lateral aspects of the ribs are called
The axillary ribs or axillary portions, since they are located within or near the axillary region.
The Thoracic Cage is
The bony structure that surrounds the organs of the chest and upper abdomen
The thoracic cavity and the abdominopelvic cavity are separated beneath the lungs by
The diaphragm.
The manubrium's upper margin is indented to form
The jugular notch, also known as the manubrial notch or the suprasternal notch. This is a positioning landmark
The Sternum has 3 parts, what are they
The manubrium, the body or gladiolus and the xiphoid process
The junction of the manubrium and the body forms a palpable bony ridge called
The sternal angle.
Cavities of the trunk are (2)
The thoracic cavity and the abdominopelvic cavity.
The term thorax referes to
The upper portin of the trunk, the chest
