Getting Familiar With The Vertebral Body Anatomy
The vertebral body anatomy is worth studying because of the role it plays in our body. But of course, studying the body of each vertebral bone will not be complete without taking into consideration the whole structure of the spinal column itself. Without the spinal column, our body would be vulnerable from injuries and traumas. Vertebral body is very important since it gives the body structure, form, and movement.
Overview of the Anatomy of Vertebral Body
Scientifically speaking, the vertebral body anatomy is part of a much greater structure, the spinal column. The body of a vertebra forms the largest portion of a vertebral bone. All the vertebral bones, except the C1, have a body but each one has a unique and different attribute depending upon its location and region. The vertebral body has another structures and parts attached to it and these are the following.
- Vertebral foramen –where the spinal cord runs through
- Spinous process – the most distal posterior part
- Transverse process – lateral part
- Laminae – located between the spinous and transverse processes
- Pedicles – located between the transverse process and the body
- Articular facets (superior and inferior) – the junction where lamina and pedicle meet
- Intervertebral foramen – opening where spinal nerves pass through
- Intervertebral discs – the junction between two vertebrae; act as shock absorbers and prevent friction
Cervical Vertebral Body Anatomy
The first and nearest vertebral bone is the C1 or also known as the atlas. It is the smallest vertebral bone and does not have a body but only a tubercle located at the front part. The C1 connects the skull and the spinal column. It is at this area that the head moves back and forth. C2 is also called the axis because it forms a pivotal joint that allows the head to rotate. C2 has the prominent odontoid process that can be seen visibly with the naked eye. C7 is also unique because it lacks spinous processes.
Thoracic Vertebral Body Anatomy
This is the middle portion of the spinal column. The first four thoracic vertebral bones have a close resemblance with the bones of the cervical region. They have almost the same design of the spinous process and articular facet. The middle four thoracic vertebral bones have attributes that are the same with the cervical region and the lumbar region. The last four vertebral bones of the thoracic region are almost the same with the lumbar bones. They are larger compared to the first eight thoracic vertebral bones.
Lumbar Vertebral Body Anatomy
This is the largest group of bones of the spinal column. It is the main weight-bearing vertebral body anatomy of the spine and connects the spine to the pelvic area.
Summary of the Anatomy of Vertebral Bone
The vertebral body anatomy is more appreciated when all its parts and functions are explored. Each vertebra is unique and designed according to their purpose.
This article has tackled some basic understanding of the spinal column. The vertebral body anatomy enables us to perform our daily tasks and give us more reasons to take care of it.
