coronary arteries Arteries that supply the heart's muscle fibers with nutrients and oxygen.
corpus callosum Tightly bundled nerve fibers that connect the right and left hemispheres of the cerebrum.
The Coronary Arteries."The Right Coronary Artery (a. coronaria [cordis] dextra) arises from the right anterior aortic sinus.
The coronary arteries arise at the point of maximum blood pressure in the circulatory system.
Blockage of coronary arteries, shown in Figure 16, is usually the result of gradual buildup of lipids and cholesterol in the inner wall of the coronary artery.
With the advent of subsecond rotation combined with multi-slice CT (up to 64-slice), high resolution and high speed can be obtained at the same time, allowing excellent imaging of the coronary arteries (cardiac CT angiography).
pharmacologic action: relaxes smooth muscle - dilates veins, dilates coronary arteries, reduces left ventricular filling pressure, lowers systemic vascular resistance, decreases myocardial oxygen demand.
Uses: treat angina pectoris.
When a person has a "coronary" we mean s/he has a block (usually an atherosclerotic plaque) in the coronary arteries that supply the heart with fresh oxygen.
Chest pain due to severe shortage of blood to the heart muscle - cells do not die
Pain only occurs during activity but not at rest
Caused by narrowing of coronary arteries (atherosclerosis)
Heart attack (myocardial infarction) ...
