Flashcards in Cardiology Deck (39)
What level is the transverse thoracic plane?
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?
Where does the azygous vein branch from?
The superior vena cava
What drains into the left venous angle?
What drains into the right venous angle?
Right lymphatic duct
Name the two groups of lymoh nodes in the lung?
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?
Which nerve is most lateral in the chest?
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
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
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?
Name the other thing we need to know in the RA but have not been told what it is or anything?
Which valve is bicuspid?
Where do the coronary arteries arise from?
The right and left aortic sinuses
Which valves have papillary muscles?
Mitral and tricuspid
What carries fibres of the RBB to the papillary muscle of the anterior cusp?
Moderator band (septomarginal trabecula)
Where are the chemoreceptor nerve endings in the heart?
Root of the aorta and IV septum
