Nest
Nest (Medicine)
Nest (pronounced: /nɛst/) is a term used in various medical contexts. It generally refers to a cluster or collection of cells or structures, often of the same type, that are grouped together in a specific pattern or arrangement.
Etymology
The term "nest" comes from the Old English nest, which means a place of rest or retreat. In the medical context, it was first used in the 19th century to describe the arrangement of cells or structures seen in certain conditions or tissues.
Usage in Medicine
In Pathology, a nest is often used to describe the arrangement of cells in certain types of cancerous tumors. For example, in Melanoma, cancer cells may be arranged in nests. Similarly, in Histology, the term can refer to the arrangement of cells in certain types of tissue, such as the islets of Langerhans in the pancreas.
In Embryology, a nest can refer to a group of cells that have migrated from their original location to a new site in the developing embryo. This is often seen in the development of the nervous system, where neural crest cells form nests that will eventually develop into various structures.
