Pleura & Lungs Flashcards
Subtypes of Parietal Pleura of Lung;
Cervical Pleura
Mediastinal Pleura
Costal Pleura
Diaphragmatic Pleura
Parietal pleura has different name, according to their region present
Cervical pleura covers
Apex of the lung
Membrane between the Inner border of 1st rib to C7 transverse process
Suprapleural membrane / Sibson’s fascia
Present over the cervical pleura
Suprapleural membrane / Sibson’s fascia is degenerative part of
Scalenus medius muscle
Suprapleural membrane / Sibson’s fascia contains
Scalenus minimus muscle
Cervical pleura is separated from the Subclavian artery and Subclavian Vein by means of
Suprapleural Membrane
Nerves supplying the Pleura of Lungs
- Intercostal Nerve
2. Phrenic Nerve
Pleura supplied by Intercostal Nerve;
- Costal pleura
2. Peripheral part of Diaphragmatic pleura
Pleura supplied by Phrenic Nerve
- Mediastinal pleura
2. Central part of Diaphragmatic Pleura
Arrangement of Structures in the Hilum of Left Lung;
A - pulmonary Artery
B - hyparterial Bronchus
V - left pulmonary Veins
Surface In front of left hilum and its related structures;
Cardiac surface
- Left auricle
- Anterolateral surface of LV
- Lingula
Lingula is?
Is extension of Lower end of Cardiac notch
Its not a lobe
Structure above; Left Hilum
Arch of Aorta
Structure behind; left hilum
Descending thoracic aorta
Nerve anterior to left hilum;
Left Phrenic Nerve + Pericardiophrenic Vesselss
Nerve Posterior to left hilum;
Left Vagus Nerve
Arrangement of Structures in the Hilum of Right Lung;
- Eparterial bronchus
- Pulmonary artery
- Hyparterial bronchus
- Lower pulmonary vein
Surface in front of Hilum of Right Lung and Structures related to it;
Cardiac surface;
- Left auricle
- Anterolateral surface of Right Atrium
- Right ventricle
Structures above hilum of Right lung;
- Arch of Azygous
* Trachea
Structures in front and above to Hilum of Right Lung;
- Right Brachiocephalic vein
* Superior Venacava
Structure Behind the Hilum of Right lung;
Esophagus
Nerve anterior to Hilum of Right Lung;
Right Phrenic Nerve + Pericardiophrenic vessels
Nerve Posterior to Hilum of Right Lung;
Right Vagus nerve
Blood supply up to Respiratory Bronchiole; is by
Bronchial artery
Number of Bronchial artery in each lung;
Right lung has - One Bronchial Artery
Left Lung has - Two Bronchial Artery
Left Bronchial, derived from
Two left Bronchial arteries are derived from Descending Thoracic Aorta
Right bronchial artery is derived from,
Right 3rd Posterior Intercostal Artery
After Respiratory Bronchiole, the lungs is Supplied by;
Pulmonary artery
Rasmussen Aneurysm is mainly due to
TB
Pseudoaneurysmal dilatation of the pulmonary artery, due to weakening of the vessels wall
By adjacent Cavitatory TB
Trachea is dividing at the level of (vertebral)
T4 > T3
Into Right and Left Bronchus (are called Primary Bronchus)
Other name for Segmental Bronchus
Tertiary Bronchus
Lobar bronchus is also known as
Secondary bronchus
The part of Lung which is aerated by Tertiary / Segmental Bronchus
Bronchopulmonary Segment
- Wedge shaped
- Surgically resectable segment
Structure Between the Two BPS
Intersegmental areolar septum
Intersegmental areolar septum is derived from
Pulmonary pleura
Intersegmental structure is
Pulmonary vein, Present between the two segments
Intrasegmental structures are;
- Tertiary Bronchus
- Bronchial artery
- Pulmonary artery
Superior Lingular and Inferior Lingular lobes of Left lung corresponds with;
Middle lobe of Right Lung
