Spheroid
Spheroid
Spheroid (/sfɪərɔɪd/) is a term used in various fields of study, including mathematics, physics, and biology. In the context of medicine, it is often used to describe the shape of cells or organisms that are approximately spherical but not perfectly so.
Etymology
The term "spheroid" is derived from the Greek word "sphaira," which means sphere, and the suffix "-oid," which means "like" or "resembling." Thus, a spheroid is something that resembles a sphere.
Definition
In medicine, a spheroid is often used to describe the three-dimensional structure of cells or tissues grown in culture. These structures are not perfectly spherical, but are elongated or flattened, resembling the shape of an egg or a rugby ball. Spheroids are often used in research to study the behavior of cells in a more realistic three-dimensional environment.
