pleurocentrum meaning in Hindi

Examples

1. There are two sacral vertebrae and the pleurocentrum of the first sacral vertebrae is noticeably smaller that the rest.
2. As in all early tetrapods, the centrum, or central part of the vertebra, is composed of two parts : the intercentrum and the pleurocentrum.
3. In living tetrapods, the main body of the vertebra is a single piece of bone called the centrum, but in temnospondyls, this region was divided into a pleurocentrum and intercentrum.
4. Just beneath the arch lies a small plate-like " pleurocentrum ", which protects the upper surface of the notochord, and below that, a larger arch-shaped " intercentrum " to protect the lower border.
5. A similar arrangement was found in primitive tetrapods, but, in the evolutionary line that led to reptiles ( and hence, also to mammals and birds ), the intercentrum became partially or wholly replaced by an enlarged pleurocentrum, which in turn became the bony vertebral body.
