Do you mean "vertebra" (one bone of the spine) or "vertebrate" (an animal with a backbone)? I'll define both briefly.

- Vertebra (singular of vertebrae): one of the repeating bones that make up the vertebral column (spine). Each vertebra typically has:
- a solid body (centrum) that bears weight,
- a vertebral arch that surrounds and protects the spinal cord (forming the vertebral foramen),
- processes for muscle and ligament attachment (spinous and transverse processes),
- joints (facet surfaces) that connect adjacent vertebrae.
Intervertebral discs sit between vertebral bodies to cushion and allow movement. In humans there are 33 vertebrae during development (7 cervical, 12 thoracic, 5 lumbar, 5 fused sacral, ~4 fused coccygeal); adults usually have 24 movable vertebrae plus the fused sacrum and coccyx.

- Vertebrate: any animal that has a vertebral column (backbone), such as fish, amphibians, reptiles, birds, and mammals.

Tell me which one you meant and I can give more detail (e.g., parts of a vertebra, differences by region, or examples of vertebrates).
