5 Types of Vertebrae

Vertebrae are the bones that make up the spinal column and provide support for the body. They come in a variety of types and sizes, each with their unique features and functions. Here are five types of vertebrae to consider:

1. Cervical Vertebrae

Cervical vertebrae are the seven vertebrae that make up the neck. They are the smallest and most mobile vertebrae and are responsible for supporting the head and neck. The first cervical vertebra is called the atlas, and the second is called the axis.

2. Thoracic Vertebrae

Thoracic vertebrae are the 12 vertebrae that make up the middle and upper back. They are larger than cervical vertebrae and are responsible for supporting the rib cage and protecting the internal organs.

3. Lumbar Vertebrae

Lumbar vertebrae are the five vertebrae that make up the lower back. They are the largest and strongest vertebrae and are responsible for supporting the weight of the upper body.

4. Sacral Vertebrae

Sacral vertebrae are the five vertebrae that make up the sacrum, a triangular-shaped bone at the base of the spine. They are fused together and are responsible for supporting the pelvis and connecting the spine to the hip bones.

5. Coccygeal Vertebrae

Coccygeal vertebrae are the four vertebrae that make up the tailbone, or coccyx. They are fused together and are responsible for providing attachment sites for muscles and ligaments.

Vertebrae are an essential component of the skeletal system and are responsible for providing support and protection for the body. By understanding the different types of vertebrae and their unique features and functions, you can appreciate the complexity and importance of the spinal column.
