CAMRT Radiography Practice Exam

What is the name of the short thick boney processes that project posteriorly from the lateral and superior aspects of the vertebral bodies?

1. Spinous processes

2. Pedicles

3. Transverse processes

4. Articular processes

The correct answer is: Pedicles

The short thick bony processes that project posteriorly from the lateral and superior aspects of the vertebral bodies are known as pedicles. Pedicles play a crucial role in the structure of the vertebral column by connecting the vertebral bodies to the transverse processes and forming part of the vertebral arch. They serve as the point of attachment for the bony components of the spine and help protect the spinal cord while providing stability. The distinction of pedicles from other structures, such as spinous processes, transverse processes, and articular processes, highlights their unique anatomical position and function. Spinous processes extend posteriorly from the vertebral arch, creating a prominent structure felt through the skin on the back, while transverse processes project laterally from each vertebra. Articular processes are involved in forming joints between vertebrae, enabling movement yet differing in shape and position compared to pedicles. Each of these components contributes to the overall structure and functionality of the vertebral column, but it is specifically the pedicles that fit the description provided in the question.
