Basal body
Basal Body
The Basal Body (pronounced: /ˈbeɪsəl ˈbɒdi/), also known as Basal Granule, is a crucial component of the cellular structure, particularly in eukaryotic cells.
Etymology
The term "Basal Body" is derived from the Latin word "basis" which means "base" and the Old English word "bodig" which means "trunk or chest". The term is used to describe the structure because it serves as the base or foundation for the formation of structures like flagella and cilia.
Definition
A Basal Body is a cylindrical structure that is approximately 500 nanometers long and 200 nanometers wide. It is primarily composed of microtubules, which are arranged in a characteristic pattern. The Basal Body serves as the organizing center for the growth of the axoneme of cilia and flagella.
Function
The primary function of the Basal Body is to provide a template for the formation of cilia and flagella. It also plays a crucial role in cell division and can transform into a centriole during this process.
