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
