The correct spelling of "false vertebra" is /fɒls/ /vɜːrˈtibrə/. The word "false" is pronounced with an "o" sound as in "pot" and "vertebra" is pronounced with a "v" sound and a long "i" sound as in "eye". A false vertebra is a non-bony segment of the spine that does not contribute to the support of the body or protect the spinal cord. It is typically made up of cartilage or fibrous tissue and is found in animals such as sharks and some amphibians.
A false vertebra is a term used in anatomical and medical contexts to describe an abnormal formation or condition that resembles a vertebra but does not possess all the characteristics of a typical vertebra. The word "false" in this context signifies that it imitates or simulates the structure of a vertebra, while not fully meeting the criteria of a true vertebra.
In terms of anatomy, a vertebra is one of the interconnected bony structures that constitute the vertebral column or backbone, which protects the spinal cord and provides structural support to the body. The typical vertebra is composed of a body, an arch, transverse processes, and several articular processes. However, a false vertebra may lack some of these anatomical features or may have additional abnormal structures.
The occurrence of false vertebrae can be congenital or acquired. Congenital false vertebrae occur due to developmental abnormalities during fetal growth. These anomalies can manifest as irregular or malformed vertebrae. Acquired false vertebrae, on the other hand, may result from trauma, degeneration, disease, infection, or surgical intervention. Such cases may involve the formation of abnormal bony growths or fusion of adjacent vertebrae, altering their normal structure.
The presence of false vertebrae requires careful evaluation and diagnosis, typically through radiological imaging techniques like X-rays, magnetic resonance imaging (MRI), or computed tomography (CT) scans. Treatment options for false vertebrae depend on the underlying cause and may involve conservative management, such as physical therapy or pain management, or more invasive interventions like surgery to correct or stabilize the abnormal vertebrae.
Any one of the fused vertebral segments of the sacrum or coccyx.
