Flashcards in Anatomy Deck (25):
Which nerve runs anterior to hilum and is the most lateral vein (anteriorly)?
Which nerve runs posterior to hilum and is the most medial vein (anteriorly)?
Order of pericardium layers
fibrous pericardium - serous pericardium - pericardial cavity filled with pericardial fluid - visceral serous pericardium
What is it called when the heart doesn't beat normally due to increased pressure in the pericardial sac from fluid
Bleeding into the pericardial sac
Pericardia centesis process
needle into the costal angle posterosuperiorly aspirating continuously
What is the transverse pericardial sinus?
a 'space' within pericardial cavity, posterosuperiorly.
Relation of transverse pericardial sinus to other vessels
posterior to ascending aorta & pulmonary trunk,
finishes anterior to SVC
Use in clinical situations
Identify the great vessels before open heart surgery
Where is the apex beat?
5th intercostal space at the midclavicular line.
What veins joins to make the brachiocephalic veins?
right and left internal jugular veins and subclavian
What joins to the SVC?
The brachiocephalic vein
The aorta sections
Ascending, Arch, Descending/Thoracic, Abdominal
Branches of aorta
Brachiocephalic trunk (right subclavian & right common carotid), left common carotid artery, left subclavian
Appendages of heart
auricle (extensions of atrium to allow for blood to be taken on
Grooves in the heart
coronary groove on right hand side (holds the RCA)
anterior interventricular groove (boundary between ventricles & holds LAD)
What is the coronary sinus and where is it?
the vein that drains all coronary vessels and is located on the base.
It drains into the RA
Right marginal artery
Posterior interventricular artery
LAD/ anterior interventricular artery
Laterally (diagonally) branch
Left marginal artery (circumflex artery)
The walls in the heart names?
What is the name of a hole in the wall and how does it cause hypoxia?
deoxygenated blood mixes and circulates the body and reduces oxygen.
The interior of RA
opening of SVC
opening of IVC
opening of coronary sinus
crista terminalis - line of rough to smooth muscle
oval fossa - depression on smooth muscle left from fetal development
The of interior ventricles
moderator bands to create a shortcut of electrical currents.
Valves & features
Tricuspid (3 cusps & tendonous chords and papillary muscles)
Pulmonary (2 cups)
Mitral (2 cusps & tendonous chords and papillary muscles)
Aortic (2 cup)
