PLEUROCENTRA Meaning and
Definition
-
Pleurocentra refers to the distinct structural elements found in the vertebrae of certain groups of animals such as reptiles and fishes. Specifically, pleurocentra are individual bony structures found on the ventral side of each vertebra.
In reptiles, pleurocentra are the principal components that make up the vertebral column. They serve as the primary skeletal support, providing rigidity and stability to the backbone. Each vertebra possesses a single pleurocentrum, which is largely responsible for bearing the weight and allowing for movement of the body. Pleurocentra often feature distinctive shapes or characteristics that can aid in identifying different species.
In fishes, pleurocentra are present in the vertebral column of some species, particularly those belonging to the teleost group. These elements are located between the neural arches and the intermuscular bones, helping to connect the spinal column with the ribs. In fishes, pleurocentra play a crucial role in providing flexibility and support to the body, enabling swimming and other locomotor activities.
Overall, pleurocentra are essential components of the skeletal system in reptiles and certain fishes. Their presence and unique features contribute to the overall structure, biomechanics, and functionality of the vertebral column, facilitating movement and supporting the body in different animals.

Etymology of PLEUROCENTRA
The word "pleurocentra" is derived from Greek. It is a combination of two Greek words: "pleura", meaning "side", and "kentron", meaning "center" or "spike". In the context of biology, "pleurocentra" refers to the vertebral elements found in certain fossil fishes, such as early ray-finned fishes, which have lateral extensions.
