OPISTHOCOELOUS Meaning and
Definition
-
Opisthocoelous is an adjective used to describe a specific anatomical characteristic found in vertebrate animals, particularly in their vertebrae. The term is primarily used in the field of biology and anatomy.
Opisthocoelous refers to a type of centrum, which is the central cylindrical bony structure that composes each vertebra in the spine. Specifically, an opisthocoelous centrum has a concave anterior surface and a convex posterior surface. This means that the front side of the centrum is indented or hollowed inward, while the back side bulges outward.
This characteristic is commonly observed in certain fossilized vertebrate species, particularly in dinosaurs and certain fish. The opisthocoelous centrum enables greater flexibility and movement in the vertebral column. By having a concave front surface, the vertebra can fit more closely to the preceding vertebra, allowing for a higher degree of mobility and a wider range of motion.
The term "opisthocoelous" is derived from the Greek words "opistho" meaning "after" or "behind," and "koilos" meaning "hollow" or "concave." Hence, opisthocoelous literally translates to "hollow on the rear" or "concave backwards." This anatomical characteristic plays a crucial role in the locomotion and physical function of the vertebrate animals possessing it.

Etymology of OPISTHOCOELOUS
The word "opisthocoelous" is derived from Greek roots: "opisthós" meaning "behind" or "at the back", and "koilos" meaning "hollow" or "cavity". In the context of anatomy, "opisthocoelous" refers to a specific type of vertebral formation where the centrum (the central part of a vertebra) is concave on its posterior (back) side and convex on its anterior (front) side. This term is often used to describe certain fossilized vertebrae or the spines of certain animals.
