Parenchyma: The key elements of an organ essential to its functioning, as distinct from the capsule that encompasses it and other supporting structures. The parenchyma is thus opposed to the connective tissue framework, or stroma, of an organ.
1 The parenchyma of the brain is nervous tissue (nerve cells and glia). The blood vessels within the brain and the connective tissue associated with these blood vessels are stroma.  The parenchyma of the malignant neoplasm is cancer cells. Other tissues, including blood vessels, which grow to support the tumor are stroma.
