ONCOCYTES Meaning and
Definition
-
Oncocytes are specialized cells found commonly in certain tissues and organs of the human body, primarily in the salivary glands, thyroid gland, and kidneys. These cells are characterized by their large size, abundant and densely-packed mitochondria, and granular appearance.
Oncocytes derive their name from the Greek word "oncos," meaning "swelling" or "mass," referring to their enlarged cell size. The cytoplasm of oncocytes contains a significant number of mitochondria, which are responsible for energy production within cells. This increased number of mitochondria gives oncocytes their characteristic granular appearance when observed under a microscope. The mitochondria within oncocytes often possess distinct structural modifications, such as increased membrane folds, indicating their high metabolic activity.
Although the precise function of oncocytes is not fully understood, their association with certain glands suggests their involvement in secretory processes. It is believed that the large number of mitochondria in oncocytes helps to meet the energy demands required for secretion. Oncocytes are also thought to play a role in fluid and electrolyte balance within the glands they reside in.
In certain pathological conditions, such as oncocytomas, which are benign tumors composed primarily of oncocytes, the number of these cells can become significantly increased. Oncocytomas are typically slow-growing and rarely cause health complications. However, further research is needed to fully elucidate the function and significance of oncocytes in normal and disease states.
Common Misspellings for ONCOCYTES
Etymology of ONCOCYTES
The word "oncocytes" has its roots in the Greek language. It is derived from the combination of two Greek words: "onkos" meaning "mass" or "bulk", and "kytos" meaning "cell". Hence, the term "oncocytes" refers to cells that have an increased amount of cytoplasm, giving them a larger size or volume compared to other cells. It is commonly used in the medical field to describe a type of cell found in certain organs, such as the thyroid gland or the salivary glands.
