Anatomy of Vertebrae

Front

What is the superior articular process?

Back

The superior articular process is a bony projection on the vertebra that articulates with the inferior articular process of the vertebra above it, allowing for movement and stability in the spinal column.

Front

What is the vertebral foramen?

Back

The vertebral foramen is the central opening in a vertebra through which the spinal cord passes, providing a protective canal for the spinal cord.

Front

What is the facet for tubercle of rib?

Back

The facet for tubercle of rib is a small, smooth surface on the vertebra where the tubercle of a rib articulates, allowing for the attachment of ribs to the spine.

Front

What is the pedicle?

Back

The pedicle is a short, thick process that connects the vertebral body to the vertebral arch, providing structural support and forming part of the vertebral foramen.

Front

What is the spinous process?

Back

The spinous process is a bony projection on the posterior aspect of a vertebra that serves as an attachment point for muscles and ligaments, and can be felt along the back.

Front

What is the function of the vertebral column?

Back

The vertebral column provides structural support for the body, protects the spinal cord, allows for flexibility and movement, and serves as an attachment point for ribs and muscles.

Front

What are intervertebral discs?

Back

Intervertebral discs are fibrocartilaginous structures located between adjacent vertebrae that act as shock absorbers and allow for slight movement between the vertebrae.

Front

What is the difference between cervical, thoracic, and lumbar vertebrae?

Back

Cervical vertebrae are the smallest and support the neck; thoracic vertebrae are larger and articulate with the ribs; lumbar vertebrae are the largest and support the lower back.

Front

What is the sacrum?

Back

The sacrum is a triangular bone formed by the fusion of five vertebrae, located at the base of the spine, connecting the spine to the pelvis.

Front

What is the coccyx?

Back

The coccyx, or tailbone, is a small, triangular bone at the end of the vertebral column, formed by the fusion of four vertebrae, providing attachment for ligaments and muscles.
