What is the Difference Between Vertebra and Vertebrae?
🆚 Go to Comparative Table 🆚The difference between "vertebra" and "vertebrae" is simple: a "vertebra" refers to a single bone of the spinal column, while "vertebrae" refers to the collection of all vertebral bones in the spine.
The vertebral column, also known as the spinal column or spine, consists of a sequence of vertebrae separated and united by intervertebral discs. Vertebrae have a complex structure composed of bone and some hyaline cartilage. They form a flexible column that supports the head, neck, and body, allowing for their movements while protecting the spinal cord.
Vertebrae vary in size, shape, and structure depending on their location in the vertebral column. There are five different regions in the vertebral column: cervical, thoracic, lumbar, sacrum, and coccyx. Each region has its own characteristic vertebral structures.
In summary:
- Vertebra: A single bone of the spinal column.
- Vertebrae: The collection of all vertebral bones in the spine.
Comparative Table: Vertebra vs Vertebrae
The main difference between vertebra and vertebrae is that "vertebra" refers to a single bone in the spinal column, while "vertebrae" is the plural form, referring to multiple bones in the spinal column. The vertebral column consists of approximately 33 vertebrae, which are separated by intervertebral discs. Here is a table summarizing the differences:
Feature | Vertebra | Vertebrae |
---|---|---|
Meaning | A single bone in the spinal column | Multiple bones in the spinal column |
Number | 1 | 33 (approximately) |
Function | Support the body, protect the spinal cord, and enable movement | Support the body, protect the spinal cord, and enable movement |
Regions | Cervical, thoracic, lumbar, sacrum, and coccyx | Cervical, thoracic, lumbar, sacrum, and coccyx |
The vertebral column can be divided into five different regions, each characterized by a different vertebral structure: cervical, thoracic, lumbar, sacrum, and coccyx. Each vertebra has a similar structural pattern, consisting of a body, a vertebral arch, and seven processes. The shape and size of vertebrae vary depending on their location in the column.
