Where to place the stethoscope to auscultate the middle lobe of the right lung?
Place stethoscope between ribs 4 and 6 in mid-clavicular and mid-axillary lines.
Where to auscultate the lung bases?
Auscultate posteriorly in the scapular line at T11 vertebral level.
What is the level of the horizontal fissure of the right lung?
The horizontal fissure is at the level of rib 4.
What is the level of the oblique fissures of the lungs?
Oblique fissures are at the level of rib 6 anteriorly, rising to the level of T3 posteriorly.
At what level does the larynx become the trachea?
The larynx becomes the trachea at C6 level.
What are important bony landmarks for the spot test?
Sternal angle and xiphoid process.
What is the arterial supply of the intercostal spaces?
Anterior intercostal arteries branch from the internal thoracic artery; posterior intercostal arteries branch from the thoracic aorta.
What is the venous drainage of the intercostal spaces?
Anterior intercostal veins drain into internal thoracic veins; posterior intercostal veins drain into azygous vein.
What is the order of the intercostal neurovascular bundles?
From superior to inferior: vein, artery, nerve (VAN).
What mnemonic helps remember diaphragm openings?
‘I Ate (8) 10 Eggs At 12.’
I 8 = inferior vena cava pierces at T8, 10 Eggs = esophagus pierces at T10, At 12 = aorta pierces at T12.
What type of muscle is the diaphragm?
The diaphragm is a skeletal muscle.
What nerves make up the phrenic nerve?
The phrenic nerve is made up of the anterior rami of C3, C4, C5.
What does the long thoracic nerve supply?
The long thoracic nerve supplies serratus anterior.
What results from paralysis of the long thoracic nerve?
Paralysis results in winged scapula.
What vessels are found on either side of the sternum?
Internal thoracic artery and a pair of veins.
What is the most inferior part of the pleural cavity?
The costodiaphragmatic recess.
What happens to the costodiaphragmatic recess with fluid build-up?
Fluid build-up results in ‘blunting of angles’ and a fluid level seen on x-ray.
What is the ‘tongue’ of the superior lobe of the left lung called?
The lingula.
Where is the cephalic vein located?
The cephalic vein is located in the delto-pectoral groove.
At what level does the trachea bifurcate?
The trachea bifurcates at the level of the sternal angle.
What structures should you be able to spot in the respiratory anatomy?
Thyroid cartilage, cricoid cartilage, arytenoid cartilage, epiglottis, hyoid bone.
Where do inguinal ligaments attach?
Between ASIS and pubic tubercle.
What is the deep ring in relation to the inguinal ligament?
The deep ring is the midpoint of the inguinal ligament.
What is a direct inguinal hernia?
A bit of peritoneum is forced through the posterior wall of the inguinal canal and directly out of the superficial ring.
