Hard things from anatomy exam 2 Flashcards
What structures are associated with the right lung
The right lung is associated with the azygous vein, the esophagus, the heart, the SVC and the IVC
What structures are associated with the left lung?
The left lung is associated with the esophagus the heart, the arch of the aorta, the left subclavian artery,and the left brachiocephalic vein
The aortic vestibule is wherw
it is found in the left ventricle right before the aortic valve
The sinus venosum is where?
It is in the right atrium
The conus ateriosis is where?
It is in the right ventricle
which layer of the plesura of the lung is sensitive to pain?
the parietal pleura
What are the layers from superficial to deep around the heart?
You have the fibrous pericardium whcih is attached to the parietal pericardium, then you have the visceral pericardium (epicardium) attached to the heart. The parietal and the viseral form the serious sac.
Layers of the heart
Epicardium, fat, myocardium, endocardium
what drains the thymus?
bracocephalic, inferior thyroid and internal thoracic
arterial supply of thymus?
internal thoracic arter
describe the path of the left phrenic nerve
The phrenic nerve crosses the aortic arch, runs across the pericardium, runs anterior to the root of the lung and then supplies the diaphragm
describe the root of the left vagus nerve
the left vagus nerve crosses the aortic arch and runs posterior tot he root of the lung
What is on the right side of the trachea?
arch of the azygous vein, the right vagus nerve and the pleura
What is on the left side of the trachea?
The arch of the aorta, the left common carotis A, the left subclavian artery and the pleura
What is posterior to the trachea?
THE ESOPHGUSSS
What is anterior to the trachea?
The SVC, the Left brachiocephalic vein, the brachiocephalic trunk, the arch of the aorta and the pulmonary trunk
What is anterior to the esophagus
the trachea, the pericardial sac,
What is posterior to the trachea
verterbal bodies and the descending aorta
What is left to the esophagus
the aortic arch
What is to the right of the esophagus?
the azygous vein
What supplies the inferior part of the esophagus?
the left gastric artery
Where are the lymphnodes that are found in the hilum?
bronchopulmonary nodes
What are the lymph nodes found @ the bifurcation of the trachea?
tracheobronchial nodes
what drains the first intercostal space? and where does it drain into
on the right and left it is the supreme intercostal vein and it drains into the right and left brachiocephalic
what drains the 2, 3 and 4 itnercostal spaces on the right and the left?
superior intrcostal veins
What drains the 5 6 7 and 8 intercostal sapces ont he left?
The acessory hemiazygous
What drains the 9-12 spaces on the left?
The hemi azygous
describe the path of the superior intercostal artery on the left
It crosses the arch of the aorta to go to the brachiocephalic
Where does the thoracic duct pass the diaphragm ? and where does it empty
L1 and it empties into the left junction of the subclavian and internal jugular
Which nodes can compress the left recurrent laryngeal nerves?
The tracheobronchial nodes
Which nerve can the tracheobronchial lymph nodes cmperess?
The left recurrent laryngeal nerve
What types of fibers do the phrenic nerve have?
motor and sensory
What type of fiberrs do the intercostal nerves have
sensory only
Where does the IVC cross the diaphragm
T8
Where does the Esophagus cross the diaphragm
T10
Where does the Aorta cross the diaphragm
T12
Contents of the superior mediastinum
superior vena cava, brachiocephalic veins, arch of the aorta, thoracic duct, trachea, esophagus, thymus, vagus nerve, left recurrent laryngeal nerve, phrenic nerve
Contents of the middle mediastinum
Heart, Pericardium, Roots of the great vessels, Main bronchi, Phrenic nerve
Contents of the posterior mediastinum
Esophagus, Thoracic Aorta, Azygos Vein, Hemiazygos Vein, Thoracic Duct, Vagus Nerve, Splanchnic Nerves
The greater splanchnic nerve contains
generalvisceral afferents and preganglionic sympathetic
the posterior portion of teh left vetrnicle is supplied by
the circumflex artery
where do you insert a needle to fix a pericardial effusion?
left 5th intercostal space
an aneurysm in the aortic arch will result in compression of the
left recurrent pharyngeal
The medial umbilical fold contains what?
The medial umbilical fold contains a fibrous remnant of the umbilical artery
what are the actions of the phrenic nerve?
somatic motor, somatic sensory, postganglionic sympathetics
What fiber types does the greater splanchnic nerve carry?
preganglionic sympathetic fibers and visceral sensory fibers
What fiebr types does the vagus nerve have?
parasympathetic preganglionic to the heart an dlungs
