BASILAR PLATE Meaning and
Definition
-
A basilar plate is a flat, elongated, and rigid bone structure that forms the floor or base of the skull. It is located in the area around the back of the nose, between the eyes, and towards the back of the head. The basilar plate is primarily composed of two bones called the sphenoid and the occipital bone.
This structure serves as a vital support system for various important organs and structures within the skull. Firstly, it provides a solid foundation for the brain and protects it from potential injury or trauma. Secondly, it forms the roof of the nasal cavity, separating it from the brain. The basilar plate also provides structural support for the eyes, by forming the posterior wall of the eye sockets (known as the orbits).
Additionally, the basilar plate serves as an attachment site for various important muscles and ligaments. Several muscles involved in chewing and swallowing, such as the pterygoid muscles, attach to the basilar plate. Ligaments that hold the skull and spine together, such as the alar and apical ligaments, are also anchored to the basilar plate.
Overall, the basilar plate is a significant component of the skull's bony framework, providing support and protection to vital structures within the head.
Etymology of BASILAR PLATE
The term "basilar" is derived from the Latin word "basis", which means "base" or "foundation". It is related to the Greek word "βάσις" (basis), carrying a similar meaning.
The word "plate" originated from the Old French word "plate", which comes from the Vulgar Latin word "platta", meaning "plate" or "dish". It ultimately traces back to the Greek word "plátys", which translates to "broad" or "flat".
When combined, "basilar plate" refers to a flat, broad structure that serves as the base or foundation of something. In anatomy and biology, the term specifically refers to a structure in the skull or vertebrae.
