Cardiology Flashcards
What level is the transverse thoracic plane?
T4/5
What is the thymus?
A gland/lymphoid tissure producing T lymphocytes in childhood but becomes involuted to adipose tissue in adult hood
What level does the trachea bifurcate?
T4/5 ( at the level of the sternal angle)
Name the branches of the thoracic aorta’s anterior surface?
Bronchial Oesophageal MEdiastinal Pericardial Phrenic
Where does the azygous vein branch from?
The superior vena cava
What drains into the left venous angle?
Thoracic duct
What drains into the right venous angle?
Right lymphatic duct
Name the two groups of lymoh nodes in the lung?
Tracheo-bronchial
Bronchopulmonary
What is the cisterna chyli?
The swollen start of the thoracic duct in the abdomen
Where does the phrenic nerve supply the diaphrgam?
Passes with the IVC into the abdomen and supplies the diaphragm fromt eh inferior aspect
Name the reminant of the ductus arteriosis?
Ligamentum arteriosum
Which nerve is most lateral in the chest?
Phrenic
Which is nerve is most medial in the chest?
Recurrent laryngeal nerve
What is a central vein?
Close to the heart such that the pressure in them is very similar to the right atrium
What is charateristic of the JVP
visable double pulsation
Not palpable
reflects the pressure in the RA
Should be no more than 3 cm above sternal angle
Where does the right recurrent laryngeal nerve hook under?
The right subclavian artery
DOES NOT ENTER THE CHEST
Where does the left recurrent laryngeal nerve hook under?
Arch of the aorta
DOES ENTER THE CHEST
Where do the supraclavicular nerves supply?
C3, C4 dermatome
‘shoulder tip’
Why can irritation of the diaphragm give you shoulder tip pain?
The nerves of the phrenic and supraclavicular nerves enter the spinal cord at the same levels so the brain ‘prefers’ the more superficial structure and so feels it as shoulder tip pain
What muscles does the left recurrent laryngeal nerve supply?
Muscles of the larynx
Where would you insert a needle for pericardiocentesis?
VIa infrasternal angle and directed superioposteriolry, aspirating continuously
What is the name of the space which lies posterior to the ascending aorta and pulmonary trunk?
Transverse pericardial sinus
What is the name of the depression in the right atrium of the heart which covers the embryological foramen ovale?
Oval fossa
Name the other thing we need to know in the RA but have not been told what it is or anything?
Crista terminalis
