Anatomy and Physiology of the Thorax and Lungs

What is the number of the intercostal space between two ribs according to the text?

Where is the sternal angle located in the thorax?

How is one supposed to locate findings in the thorax along the vertical axis?

What should be used as a reference point to locate findings in the thorax?

What should be noted about the number of intercostal spaces between two ribs?

Intercostal Spaces

Each intercostal space is numbered according to the rib above it.
For example, the intercostal space between ribs 3 and 4 is called the 3rd intercostal space.

Sternal Angle

The sternal angle, also known as the angle of Louis, is located at the junction of the manubrium and the body of the sternum.
It corresponds to the second rib and serves as a key anatomical landmark in the thorax.

Locating Findings Along the Vertical Axis

Findings in the thorax can be located along the vertical axis by using anatomical landmarks like the sternal angle.
This approach helps in identifying the vertical positioning of thoracic structures.

Reference Points in the Thorax

The sternal angle is a crucial reference point for locating thoracic findings.
By identifying the sternal angle, practitioners can accurately determine the position of various organs and structures.

Intercostal Space Note

The number of intercostal spaces between two ribs is one less than the higher numbered rib.
This means that there is a direct correlation between the rib numbers and the intercostal space designation.
