CVS Anat Flashcards
(use this in addition to Netter's cards!)
What are the 2 layers of the pericardium (+ sub-layers?)
Fibrous pericardium +
Serous pericardium
- Parietal layer (stuck to fibrous)
- Visceral layer (stuck to heart)
Where is the pericardial cavity?
What does pericardial cavity contain?
Between Visceral and parietal layer of serous pericardium.
Serous fluid.
Another name for visceral layer of serous pericardium?
Epicardium
Nerve supply of pericardium?
Phrenic nerve (w somatosensory & motor fibres):
- Fibrous pericardium +
- Parietal layer of serous pericardium
Symp. fibres arising from T1-4 + Vagus nerve (psymp): (viscerosensory n motor)
- Visceral layer (stuck to heart)
3 cavities that thoracic cavity contains?
mediastinum (heart + root of great vessels) + 2 pulmonary cavities
Boundaries of superior vs inferior mediastinum?
Divisions of inferior mediastinum?
Structures in anatomical divs of inf mediastinum?
sup: T1 - T4-5 (sternal plane)
inf: T4-5 - diaphragm
Divs: Ant, Middle, Post
Ant: in front of heart
Middle: heart + root of great vessels
Post.: behind heart
Structures:
Ant: thymus, etc
Middle: =
Post.: thoracic vertebrae, vagus nerve, etc
What structures does posterior mediastinum contain?
TVATET (see notes)
Arrangement of root of great vessels?
SAP:
SVC
Asc Aorta
Pul. trunk
Phrenic vs vagus nerve runs?
Phrenic front
Vagus vehind root of lung
3 branches of aortic arch?
(from R -> L) BCS
right brachiocephalic artery = brachiocephalic trunk
left common carotid artery
left subclavian ARTERY
Is aortic arch in inf/sup mediastinum and why
Sup; it starts and ends at T4-5 level
Location of aorta as it descends?
Left –> center
Location of azygos vein as it ascends?
on right side of body (joining IVC and SVC)
Where does azygos vein drain blood from and what veins does it receive?
thorax region structures
esophageal vein, etc
Fill the 2 lymphatic drainage locations -> ducts in body
Where do each duct drain?
(see pic of guy)
- right side of H&N + right upper limb –> right lymphatic duct
- everywhere else of body –> left lymphatic duct (aka. thoracic duct)
RLD into right braachioceph vein
LLD into left =
