Anatomy of the Thorax Flashcards
Borders of the superior thoracic aperture
T1
Rib 1
Sternum
Suprapleural membrane
Attached to transverse process of C7 and medial margin of rib 1
Orders of structures at the superior thoracic aperture from back to front
Vertebrae, esophagus, trachea, artery place, nervous plane, venous plane
Crura
Tendons that extend from bottom of diaphragm to vertebrae
One to L3 on the right and the other to L2 on the left
Where do the 1. Inferior vena cava 2. Esophagus 3. Aorta pass through the diaphragm
- tendon part - at T8 level
- muscle - at T10 level
- passes behind - at T 12 level
What nerves innervate the diaphragm
Phrenic nerves (C3/4/5)
True vs false ribs
True: 1-7 (articulate with vertebrae and directly with sternum)
False: 8-12 (vertebrae and indirectly/not at all with sternum)
Typical ribs
Articulate with their vertebrae and the one above
Where does the sternal angle correspond on the vertebral columb
T4/5
Intercostal nerves
The anterior rami of thoracic nerves (T1-T11)
Least protected structure in costal groove
Which nerves supply anterior abdominal wall
T7-12
Which dermatome is the umbilicus in?
T10
Which bronchi is more vertical and wider
The right
Fissures in right and left lung
Right: middle and oblique
Left: oblique
Borders of axillary inlets
Scapula
Clavicle
First rib
Which sternocostal joint is not a true joint?
The first
Where are the pain receptors in the pleura?
Few in the visceral pleura
Many in the parietal pleura
What vertebral level does the trachea
1. begin
2. divide
at?
- C6
2. T4/5
Lingula
On left lung only
Projection of the upper lobe
