Lungs and Diaphragm Flashcards
Inferior limit of the parietal pleura on the midaxillary line
10th rib
On the midaxillary line, thoracentesis can be performed between these ribs so as to avoid puncturing the lung
8th and 10th ribs
This side of the pleura is sensitive to stretch but insensitive to common sensation
Visceral pleura
Subdivision of the parietal pleura that is also known as the cupula
Cervical pleura
The inferior and superior lingular segements are part of what lobe of the lung?
Left superior lobe
The lung apex extends _ cm above the clavicle
2.5
The trachea is _ long and _ in diameter
5 inches, 1 inch
The trachea spans these vertebral levels
C6 to T4
Total number of secondary bronchi
5
The eparterial bronchus is also known as the
Right superior bronchus
Bronchopulmonary segments of the inferior lobes
Superior, Anterior basal, Medial basal, Posterior basal, Lateral basal
Three segments of the right superior lobe
Apical
Anterior
Posterior
The lateral and medial bronchopulmonary segments form the
Right middle lobe
Most common site of aspiration when lying supine
Superior segment of the right lower lobe
The inferior lingular segment of the left superior lobe is the most common site of aspiration when patients are (position)
Lying on the left side
Malignant neoplasms of the superior pulmonary sulcus involving the lung apex
Pancoast tumor
Horner’s syndrome affects this part of the nervous system
Cervical sympathetic ganglia
The inferior and superior tracheobronchial lymph nodes drain into the
Paratracheal lymph node
The first two ribs are supplied by what artery?
Superior intercostal artery of the costocervical trunk
The upper six ribs are supplied by the
Anterior intercostal arteries
The posterior intercostal arteries are branches of the
Thoracic aorta
In thoracentesis, the needle is passed on the superior side of the ribs to avoid damage to the
Neurovascular bundle
The respiratory bronchiole is lined with _ epithelium
Simple cuboidal
In the respiratory tree, glands and cartilage are absent from _ onwards
Bronchiole
Sensory innervation of the diaphragm
Central: Phrenic merve
Peripheral: Intercostal nerves
The right lymphatic duct drains the:
Right side of the body above the diaphragm
The right phrenic nerve pierces enters this diaphragmatic hiatus
Caval hiatus
Aside from the esophagus, this structure passes through the diaphragm at the level of T10
Vagus nerve
Dermatome at the xiphoid
T7
