The brachial plexus runs in the same track as the _____.
left subclavian artery
Thoracic outlet
the space between the clavicle and the 1st rib
The brachial plexus is a network of nerves originating from the levels of _____
C5-T1
The tract of the brachial plexus runs parallel to __________, which provides a landmark for plotting coronal brachial plexus scan planes.
Subclavian artery and vein
Symptom of Thoracic Outlet Syndrome:
numbness when the arm is above their head
Thoracic Outlet Syndrome
The compression of the thoracic outlet causing impingement of the brachial plexus, this usually results in pain or numbness of the shoulder, arm, or hands.
ECG Monitoring is achieved by placing MR-compatible leads and acquiring images when the heart is at rest. Image acquisition is performed between the _______ which would be during _____.
R-R Interval during distole
The pulmonary vein carrying deoxygenated blood rises from the:
left atrium
The most anterior chamber of the heart is the:
Right ventricle
The most posterior chamber of the heart is the:
Left Atrium
The ______ has the thickest myocardicum compared to all other chambers of the heart.
Left ventricle
The _______ provides prevention of blood flow back from the left ventricle into the left atrium.
Bicuspid or Mitral Valve
The Ascending and Descending aorta are both best visualized on ____ images of the heart.
Sagittal
The area of the heart with the fastest flow of blood is at the ____ due to its close proximity to the muscle.
Ascending Aorta
Coronary arteries are originated from the______
Aortic Root
3 arteries that arise from the Aorta:
- Brachiocephalic artery
- Left Common Carotid artery
- Left Subclavian artery
The inherent pacemaker of the heart supplying electrical signal to initiate contraction and is located in the right atrium and the entrance of the superior vena cava:
Sinoatrial node (SA node)
Receives the electrical signal from the SA node and relays signal to Bundle of His once ventricles fill with blood
Atrioventricular node (AV node)
The Atrioventricular node (AV node) receives the electrical signal from the SA node and relays signal to the:
Bundle of His
Bundle of His branches off onto the periphery of the left and right ventricles along the:
Purkinje fibers
Where depolarization and contraction of the ventricles occur:
Purkinje fibers
