Answer 2

Types of centrum of vertebrae:

Centrum is the flat and thick portion of the vertebra which carries maximum load and pressure of the body. It is no doubt thick, and when we see the evolutionary line, we can see different types of centrum.

The types of centrum are

1. Procoelous – concave in front and convex at back.  
2. Opisthocoelous – convex in "front and concave" at back.
3. Heterocoelous – convex at both "front and back".
4. Amphicoelous – concave at both front and back.
5. Acoelous – no concavity or convexity at front or back.
6. Amphiplatyan
