Valves of the Heart, Cardiac Skeleton, and Connective Tissue of Heart

The “skeleton” of the heart is, of course, not made of bone. Between the atria and the ventricles, a layer of thick connective tissues surrounds the valves of the heart, and provides an attachment point for the connective tissue that keeps the heart from over-expanding. The chordae tendineae also use the cardiac skeleton as one of their primary attachment points.

Posterior view of arteries and veins of the heart and lungs

The coronary sinus is clearly visible, as the largest vein on the body of the heart. “Coronary” means “crown”, so if one thinks of the heart as a head, anything labeled “coronary” likely goes around it in a somewhat-encircling fashion.

The anterior cardiac veins drain directly into the right atrium, but the majority of the other cardiac veins (excluding some of the smallest), including the great cardiac vein, drain into the coronary sinus. The junction between the right atrium and the coronary sinus is marked by the Thesbian valve.

The inner ear and labyrinth, in situ and isolated. Innervation and vasculature displayed in situ.

Arterial and venous circulation of the tympanum (eardrum).

You can see how the inner ear sits within the temporal bone in these illustrations, and can get more of an idea how it fits into the skull. The vestibulocochlear nerve is shown clearly as the white chord-like structure entering from the bottom of the center illustration. This nerve carries signals to the brain regarding both hearing and balance.
