- 1Define pleuraA closed sac of serous membrane
Lines the lungs (visceral pleura)
Lines the thoracic wall (parietal pleura)
Also pleura is called mesothelial membrane - 2What is the space between the parietal and visceral pleura called?Pleural cavity
Contains a small amount of serous fluid-around 10ml
Creates a very thin layer lkeading to cohesion of parietal and visceral for breathing - 3What is the superior boundary of the pleural cavities? What is the inferior boundary? What is the medial boundary?Just above rib 1 into the root of the neck
Just above the costal margin
Mediastinum - 4What is the clinically most important recess in the pleural cavities?Costodiaphragmatic recess
- 5What is the costodiaphragmatic recess?Potential space between the inferior of the lungs and the inferior of the pleural cavities
This potential space therefore has the potential to accumulate fluids within a pleural effusion - 6What is the inferior boundary of the lungs and pleural cavities?Lungs; Inferior margin of rib TVI midclavicular, inferior margin of TVIII midaxillary and body of TX
Pleural cavity; Inferior of rib VIII midclavicular, inferior of rib X midaxillary and body of TXII - 7What are the subdivisions of the parietal pleura?Mediastinum part-Reflects onto mediastinum
Costal part-Reflects onto thoracic wall
Diaphragmatic part-refelects onto diaphragm
Cervical pleura-lines cervical extension of the parietal pleura - 8What is the innervation of the parietal pleura?Phrenic and intercostal nerves
Phrenic supplys central diaphragmatic part and mediastinal part
Intercostal nerves supply central diaphragmatic part and costal part - 9What is the parietal pleura sensitive to?Pain, temperature and pressure
- 10What is referred pain?perception of pain in an area of the body some distance away from the actual area diseased or malfunctioning
This area is supplied by the same spinal nerves - 11Where would pain in the pareital pleura be felt?Damage to lower intercostal pleura will cause pain in lower abdomen
Damage to central diaphragmatic part will cause pain in neck and ipsilateral parts of the shoulders - 12Why does referred pain occur?Dermatomes of spinal nerves
- 13What is the innervation of the viseral pleura?Pulmonary plexus
- 14What is the viseral pleura sensitive too?ONLY stretch
NOT pain, temperature or pressure - 15Posterior to the lower part of the sternum, does the right and left pleura come as close to the midline as eachother?No
Left pleura is further from midline than the right
Due to the heart bulging to the left - 16What is the pathway of the oblique fissure?Runs from level of spinous process of T4, crosses the 5th intercostal space and follows the contour of rib VI
- 17What is a bronchopulmonary segment? How many are there on each lung?Smallest functionally independent region of the lung
10 on the right and 9 on the left - 18What is the neurovascular supply to bronchopulmonary segments?Each bronchopulmonary segmment has an associated segmental bronchi and pulmonary artery branch
Trbutaries of the pulmonary veins run along the margins of each segment, intersegmentally - 19What is the shape of a bronchopulmonary segment?Shaped like a cone
Apex at the segmental bronchi
Base peripheral on the surface of the lung - 20What are the bronchopulmonary segments on the right lung from 1-10?A PALM SEED MAKES ANOTHER LITTLE PALM
1=Apical segment
2=Posterior segment
3=Anterior segment
4=Lateral segment
5=Medial segment
6=Superior segment
7=medial basal segment
8=anterior basasegment
9=lateral basal segment
10=posterior basal - 21What are the bronchopulmonary segments of the left lung from 1-10/9A PALM SEED MAKES ANOTHER LITTLE PALM
1+2=Apicoposterior segment
3=Anterior segment
4=Superior lingular segment
5=inferior lingular segment
6=Superior segment
7=Medial basal segment
8=Anterior basal segment
9=Lateral basal segment
10=Posterior basal segment - 22What is a lobectomy?The removal of an entire lobe of the lung
- 23What is a pneumonectomy?Removal of an entire lung
- 24What is a segmentectomy?Removal of a bronchopulmonary segment
- 25What is a pulmonary thrombembolism?Obstruction of a pulmonary blood vessel by a blood clot that became dislodged from another part of circulation
