Definition: The word "agglutination" in Greek, often translated to English as "aggregation," refers to the process by which a group of cells, such as a neuron or a cell in a cell nucleus, come together into larger units, which are called aggregates (also known as ganglia). The function of these aggregates is not always understood completely. The word was originally used in classical Greek medicine and the Bible. In ancient texts, it referred to the ability of certain cells (such as neurons) to combine or "agglomerate" together to form larger structures called agglutination units. In modern times, the term has become more general and is sometimes applied more broadly to aggregates found in cells throughout the body including blood cells, fat cells, epithelial cells, muscle cells, and nerve cells. Aggregation in the body is often associated with the release of neurotransmitters or hormones into the bloodstream or to certain tissues.
