The lumbar vertebrae anatomy are, in human anatomy, the five vertebrae between the rib cage and the pelvis. They are the largest segments of the vertebral column and are characterized by the absence of the foramen transversarium within the transverse process (as it is only found in the cervical region), and by the absence of facets on the sides of the body. They are designated L1 to L5, starting at the top. The lumbar vertebrae anatomy help support the weight of the body, and permit movement.
In humans, there are twelve thoracic vertebrae and they are intermediate in size between the cervical and lumbar vertebrae anatomy; they increase in size going towards the lumbar vertebrae, with the lower ones being a lot larger than the upper. They are distinguished by the presence of facets on the sides of the bodies for articulation with the heads of the ribs, and facets on the transverse processes of all, except the eleventh and twelfth, for articulation with the tubercles of the ribs.
In vertebrates, cervical vertebrae are the vertebrae of the neck, immediately below the skull. Thoracic vertebrae in all mammalian species are those vertebrae that also carry a pair of ribs, and lie caudal to the cervical vertebrae. Further caudally follow the lumbar vertebrae, which also belong to the trunk, but do not carry ribs.

The vertebrae anatomy is an extremely important topic to understand. Vertebrae are the bones in the spine that make up the backbone. They are stacked on top of each other to form a column and provide support for the body. Each vertebra is made up of three parts: the body, the vertebral arch, and the process. The body is the main part of the vertebra and is responsible for providing support and protection for the spinal cord. The vertebral arch is the curved shape of the vertebra that helps to hold the vertebrae together. The process is the small projections that extend from the vertebrae and are used for muscle attachments and ligament attachments.
The vertebrae anatomy is complex, but it is important to understand in order to keep the spine healthy. The vertebrae are essential for providing stability and protection for the body, and any dysfunction or misalignment of the vertebrae can lead to serious problems. It is important to maintain good posture and keep the vertebrae anatomy in alignment in order to prevent any long-term damage or injury.
