Lungs Flashcards
Cervical pleura which is a subdivision of the pleura of the lungs is AKA
Cupula
In thoracentesis needle should be inserted at MIDAXILLARY LINE between which 2 ribs
Ribs 8 & 10
Which pleura is sensitive to pain, touch, temperature and pressure
Parietal pleura
Costal
Nerve?
Intercostal nerve
Mediastinal
Nerve?
Phrenic nerve
Diaphragmatic
Nerve?
Phrenic and intercostal
Insensitive to common sensation but sensitive to stretch
Visceral pleura
Visceral pleura is innervated by
Pulmonary plexus
How many lobes in right lung
3 lobes
What fissures in right lung
Oblique
Horizontal
Fissures in left lung
Oblique
How many lobes in left lung
2 lobes
Where the parietal and visceral pleura meet
Root of the lung
Forms the lower division of the upper lobe of the left lung
Superior and inferior lingular
Largest subdivision of a lobe
Bronchopulmonary segments
Anatomical and surgical unit of lung
Bronchopulmonary segments
Called epaterial bronchus
Right superior bronchus
Lining epithilium of bronchi
Pseudostratified epithelium with goblet cells
FBA
When sitting or standing where will it lodge
Posterior basal BPS of the right lower lobe
FBA
Supine where will it lodge
Superior BPS on the right lower lobe
FBA
Lying on the right side
Posterior BPS of the right upper lobe
FBA
Lying on the left side
Inferior lingular BPS of the left upper lobe
In aspiration pnemonia whicg BPS is usually associated
Superior segments of lower lobe
Bronchial A is from
Descending thoracic aorta
Pulmonary arteries is from
Pulmonary trunk
Bronchial veins drain into
Azygous and hemiazygous veins
Pulmonary veins empty in
Left atrium
Horner syndrome
Ptosis Enopthalmos Miosis Anhydrosis Vasodilation
In thoracentesis
Needle is inserted
_____ the rib
To avoid damage to intercostal nerve and vessels
Above the rib
Thoracentesis
Needle is introduced to pleural cavity in the
Midaxillary linein 8th intercostal space
Thoracentesis
Highest level at which this procedure might safely done without injuring the lung is
8th ICS
Thoracentesis
Lowest level of the pleural cavity will lie at the level of which rib at the end if expiration un the MAL
10th
