in the heart, the endocardium is the innermost layer of tissue that lines the chambers of the heart. its cells, embryologically and biologically, are similar to the endothelial cells that line blood vessels

I don't think the suffix "-um" has a true definition

[Daytonite, BSN, RN]

The -um is a Latin suffix that is attached to the two combined word roots, endo- and cardio-, to form a noun. The word would not be correct if combined as endocardio, so the -um is attached to make the word the correct part of speech, a noun, in this case--endocardium.

The heart is encased in two protective layers. The outer layer - the pericardium - covers the heart. It folds in on itself at the aorta forming the epicardium of the heart. Between these layers is a small amount of fluid that affords the layers a non-stick surface.

The epicardium forms the outer layer of the heart, the myocardium forms the middle layer and the endocardium the innermost layer.

The endocardium has a smooth inner surface to allow blood to flow easily through the heart's chambers.

The muscular myocardium is the thickest layer and the workhorse of the heart.

I think the suffix is actually "-ium," not "-um." The suffix "-ium" comes from Greek and means "small" (Ref: Dictionary of Word Roots and Combining Forms, D.J. Borror).

The literal translation of "endocardium" would then be something like, "small stuff on the interior of the heart."

This book lists no suffix "-um" although the word datum/data comes to mind. Perhaps that's just a Latin (I think) singular/plural construction that has no specific meaning as a suffix.

Other "-ium" words that quickly come to mind include:

• paramecium
  
• Endomysium/perimysium/epimysium
  
• Endoneurium/perineurium/epineurium

TRUE!!!!

[suespets]

think of the um in any word as " of " or "pertaining to."
