Exam 2 Flashcards
Ch. 19
List the 4 anterior thoracic landmarks
- Suprasternal notch: hollow U-shaped depression just above the sternum, between the clavicles
- Sternum
- Manubriosternal angle: lines up with the second rib
- Costal angle: R & L costal margins form an angle (usually 90° or less) where they meet at the xiphoid process
Ch. 19
What is the Manubriosternal Angle?
- angle of Louis
- in line / lines up with 2nd rib
- useful place to start counting ribs
Ch 19
What are the 4 Posterior Thoracic Landmarks?
- Vertebra prominens: most prominent bony spur protruding at the base of the neck when you flex your head
- Spinous processes: align with their same numbered ribs only down to T4. after T4, the spinous processes angle downward from their vertebral body & overlie the vertebral body & rib below
- Inferior border of scapula: usually located at the 7th or 8th rib
- Twelfth rib
Ch 19
What is unique about the spinous processes landmark?
- align with their same numbered ribs only down to T4
- After T4 the spinous processes angle downward from their vertebral bodies & overlie the vertebral body & rib below
Ch 19
What are the important reference lines to keep in mind when assessing the thorax & lungs?
- Midsternal
