coronary cushion

From this it is clear that the condition depends primarily upon the amount and condition of the blood supplied to the coronary cushion.

This should run immediately under the coronary margin of the wall, and should stop short of injuring the coronary cushion beneath.

Repair after this operation is rapid, and takes place both from the exposed podophyllus membrane and from the coronary cushion.

Superiorly the cavity is quite narrow, and extends to near the lower surface of the coronary cushion, while inferiorly, at its open portion, it is often 1/2 inch to 1 inch wide.

The coronary cushion being continuous with the plantar, the backward and outward movements of the latter will tend to pull upon and tighten the former, especially in front.
