Embryology
What is this (be specific) and what is the embryological origin?
Ascending aorta; truncus arteriosus
Please identify the structure and what is its function?
left ventricle and pumps blood to the rest of the body (systemic circulation)
What is this and what does it connect?
Pulmonary Trunk; right ventricle to right and left pulmonary arteries to lungs
What electrical bundle is located here and what is its function?
SA node: it determines rate and rhythm
please label all arrows.
superior vena cava, right atrium, inferior vena cava, aortic arch, main pulmonary artery, left atrial appendage, left ventricle
What is this and what is its embryological origin?
right common cardinal vein and proximal portion of the right anterior cardinal vein
Please identify this muscle and what chamber is it located in.
pectinate muscle; right atrium
What are all the branches off the aorta? Medial to lateral on both sides
Brachiocephalic artery splits into right subclavian and right common carotid; left common carotid and left subclavian artery
Please identify this bundle (in order from top to bottom)
Intercostal neuromuscular bundle: vein, artery, and nerve (VAN)
Please level all arrows.
left atrium, left ventricle, inferior vena cava, right ventricle, right pulmonary artery, left pulmonary artery, aorta
Please identify what the probe is pointing at and what two vessels it connects.
Ligamentum Arteriosum; aorta to left pulmonary artery
Please identify when does it contract and why?
Papillary muscle and systole contraction - prevents prolapse
Please identify this vessel and what vessels drain into it?
SVC: left and right brachiocephalic vein, azygos vein
What nerve is this? What would happen clinically if this were to be damaged?
Left recurrent laryngeal nerve; hoarseness/dysphagia (slightly)
Please label all the arrows.
From top left and clockwise: SVC, ascending aorta/proximal arch, thoracic aorta/distal arch, esophagus, azygos vein
Please label all sections demonstrated.
T.A., Bulbus cordis, primitive ventricle, primitive atrium, sinus venosus
Please identify which and all parts of this valve.
Aortic valve, annulus (not pictured?), Left semilunar cusp (coronary), right semilunar cusp (coronary), posterior semilunar cusp (non coronary)
Please identify these vessels.
Azygos vein, hemiazygos vein, and accessory hemiazygos vein
What nerve bundle is this and identify each component.
Sympathetic trunk/chain; white and grey rami communicates, thoracic ganglia
Please level all the arrows.
From top left and clockwise: liver, Right ventricle, liver, fungus of the stomach, left lung, esophagus, Right lung, inferior vena cava
Right common cardinal vein, right horn, right posterior cardinal vein, right umbilical vein, right vitelline vein (same on left side)
So you think you know every muscle of the heart, eh? Name every single muscle of the heart
Atrium: pectinate muscle, smooth atrial muscle
Ventricles: papillary muscles, trabecular carnae, smooth ventricle muscle
Septal muscle?
Please identify this vessel and what parts of the heart does it supply?
RCA; right atrium, right ventricle, SA node, inferior and posterior portions of left ventricle, and posterior 1/3 of the inter ventricular septum
What is this green vessel and what does it drain into?
Thoracic duct; junction of left subclavian veins and left internal jugular vein
Please label all arrows.
