Cheer Up! Stop sulking.
What is the anterior interventricular sulcus?
This muscular band is located in the right ventricular apex and connects the interventricular septum to the anterior papillary muscle.
What is the moderator band?
This vessel likes to hang out with the posterior descending artery in the posterior interventricular sulcus.
What is the middle cardiac vein?
Striated heart muscle cells.
What are cardiomyocytes?
The parts include papillary muscles, chordae tendineae and leaflets.
What are the atrioventricular valves?
OR
What are the tricuspid and mitral valves?
This is where the circumflex artery finds its groove.
What is the left atrioventricular sulcus?
This muscle band begins from the RV septum and extends across the tricuspid orifice onto the anterior wall.
What is the parietal band?
This vessel is tucked into the right atrioventricular groove and joins the coronary sinus.
What is the small cardiac vein?
These make up organized rows within the myocardial bundles.
What are myofibrils?
The parts include cusps, nodules and lunule.
What are the semilunar valves?
OR
What are the pulmonic and aortic valves?
The right coronary artery dives into this groove.
What is the right atrioventricular sulcus?
A band of muscle located just inferior to the pulmonary valve.
What is the supraventricular crest?
This vessel has a long journey from the apex of the heart all the way to the coronary sinus.
What is the great cardiac vein?
These hold those cardiac muscle cells together, end to end.
What are intercalated discs?
The third leaflet that differentiates the tricuspid valve from the mitral valve?
What is the septal leaflet?
This groove knows how to get down and shake it's booty! (Also where the middle cardiac vein hangs out.)
What is the posterior interventricular sulcus?
This muscle band originates at the RV septum and bifurcates into two other bands.
What is the septal band?
This vessel brings blood return from the hardest working chamber of the heart.
What is the posterior vein of the LV?
Repeating units of actin and myosin within the myofibrils.
What are sarcomeres?
The most anterior-facing valve of the heart.
What is the pulmonary valve?
Does it actually exist or do we only imagine this line running along the external right atrium?
What is the sulcus terminalis?
This spaceship, er, I mean band goes by another name too.
What is the crista supraventricularis?
Venous return from the left atrium moves through this vessel.
What is the vein of Marshall or the oblique vein? Or even, what is the oblique vein of Marshall?
Intercellular channels distributed throughout the myofibrils.
What is the sarcoplasmic reticulum?
Cartilaginous tissue found around the valves and structures.
What is the annulus fibrosus or the skeleton of the heart?
