Definition of Vertebra
A vertebra (singular) is one of the individual bony or cartilaginous segments of the spinal column. These bones are arranged in a series from the base of the skull to the tailbone, forming the backbone. Each vertebra protects the spinal cord and supports the body’s structure, allowing for flexibility and movement. The plural form, vertebrae, refers to multiple such segments.
In anatomical and medical contexts, accurate use of these terms is vital for precise communication. The word “vertebra” originates from Latin, where it also referred to a joint or segment.
Understanding its etymology helps to explain why its pluralization follows Latin rather than typical English rules.
Structural Breakdown
The term “vertebra” is a noun, specifically a singular noun when referring to a single bone in the spinal column. Its plural form, “vertebrae,” is an irregular plural.
Most English nouns form their plural by adding “-s” or “-es,” but “vertebra” follows the Latin pluralization rule, changing the “-a” ending to “-ae.”
The structural breakdown can be summarized as follows:
- Singular: vertebra
- Plural: vertebrae
Knowing this pattern is crucial for recognizing and using both forms correctly. The shift from “-a” to “-ae” is a common characteristic of many Latin-derived nouns in English, such as “formula” becoming “formulae” and “antenna” sometimes becoming “antennae.”
Types and Categories of Vertebrae
The vertebral column is divided into several regions, each characterized by vertebrae with distinct shapes and functions. Understanding these categories can provide a deeper appreciation for the complexity of the spine.
Cervical Vertebrae
Located in the neck, cervical vertebrae are the smallest and most mobile. They support the head and allow for a wide range of neck movements.
There are seven cervical vertebrae, numbered C1 to C7.
Thoracic Vertebrae
These vertebrae are located in the upper back and articulate with the ribs. They provide stability to the rib cage and protect the vital organs in the chest.
There are twelve thoracic vertebrae, numbered T1 to T12.
Lumbar Vertebrae
Found in the lower back, lumbar vertebrae are the largest and strongest. They bear the majority of the body’s weight and provide stability for the lower back.
There are five lumbar vertebrae, numbered L1 to L5.
Sacral Vertebrae
These vertebrae are fused together to form the sacrum, a triangular bone at the base of the spine. The sacrum connects the spine to the pelvis and provides stability for the hips.
There are typically five sacral vertebrae, fused together and referred to as S1 to S5.
Coccygeal Vertebrae
Also fused, these vertebrae form the coccyx, or tailbone. The coccyx provides a point of attachment for ligaments and muscles of the pelvic floor.
There are typically three to five coccygeal vertebrae, fused together.
The table below summarizes the categories of vertebrae:
| Category | Location | Number | Function |
|---|---|---|---|
| Cervical | Neck | 7 | Support head, allow neck movement |
| Thoracic | Upper back | 12 | Articulate with ribs, protect organs |
| Lumbar | Lower back | 5 | Bear body weight, provide stability |
| Sacral | Base of spine | 5 (fused) | Connect spine to pelvis |
| Coccygeal | Tailbone | 3-5 (fused) | Attachment for pelvic floor muscles |

Usage Rules for Vertebra and Vertebrae
The rules for using “vertebra” and “vertebrae” are straightforward: use “vertebra” when referring to a single spinal bone and “vertebrae” when referring to two or more. However, some nuances can help ensure correct usage in all contexts.
- Singular Reference: Use “vertebra” when discussing a single, specific bone.
- Plural Reference: Use “vertebrae” when discussing multiple spinal bones.
- Formal vs. Informal: While some Latin plurals have Anglicized alternatives, “vertebrae” is the standard and preferred plural in both formal and informal contexts.
- Consistency: Maintain consistency in your writing. If you start using “vertebrae,” continue to use it throughout the text when referring to multiple bones.
Understanding these rules and applying them consistently will help you avoid errors and communicate effectively.

Advanced Topics: Latin Plurals in English
The pluralization of “vertebra” highlights a broader phenomenon in English: the retention of Latin plural forms for words of Latin origin. While many such words have adopted regular English pluralizations (adding “-s” or “-es”), some retain their Latin plurals, often in formal or technical contexts.
Examples include:
- Formula: formulae (or formulas)
- Radius: radii
- Curriculum: curricula (or curriculums)
- Analysis: analyses
- Crisis: crises
The choice between using the Latin plural and the Anglicized plural often depends on context, formality, and common usage. In scientific and academic writing, Latin plurals are often preferred for their precision and historical accuracy.
However, in more informal contexts, the Anglicized plurals are often acceptable and sometimes even preferred.
The table below illustrates some Latin plurals and their Anglicized alternatives:
| Singular | Latin Plural | Anglicized Plural | Preferred Context |
|---|---|---|---|
| Formula | Formulae | Formulas | Technical, Scientific |
| Radius | Radii | Radiuses | Technical, Mathematical |
| Curriculum | Curricula | Curriculums | Academic, Formal |
| Antenna | Antennae | Antennas | Technical, Zoological |
| Index | Indices | Indexes | Mathematical, Library Science |

Yes, several other words of Latin origin follow the same pluralization rule. Examples include “formula” (formulae), “antenna” (antennae), and “larva” (larvae).
Recognizing these patterns can help you learn similar pluralizations.
The vertebrae are divided into five main regions: cervical (neck), thoracic (upper back), lumbar (lower back), sacral (base of the spine), and coccygeal (tailbone). Each region has vertebrae with distinct characteristics and functions.
Using these terms correctly ensures clarity and precision in your writing and speaking. It demonstrates attention to detail and a strong command of English grammar, which enhances your credibility and professionalism.
Yes, it is a fairly common mistake, especially among non-native English speakers or those unfamiliar with Latin pluralization rules. The irregular plural can be confusing, leading to errors like using “vertebras” or misusing the singular and plural forms.
Certainly! “The doctor explained that while each vertebra plays a crucial role, the vertebrae collectively provide essential support and flexibility to the spine.” This sentence correctly uses “vertebra” to refer to an individual bone and “vertebrae” to refer to the bones as a group.
No, there are no significant regional differences in the usage of these terms. The rules for using “vertebra” and “vertebrae” are consistent across different English-speaking regions.
You can consult grammar textbooks, online dictionaries, and style guides for more information on Latin plurals in English. Additionally, practicing with exercises and seeking feedback from teachers or language partners can be helpful.
