What are the lumbar vertebrae?
lumbar vertebrae are a group of five individual bones of the spine. Together they form a lumbar area that is one of five different regions in a column or spine. It creates inside the intersection of the spine in what is commonly called a small back. The entire adult column is composed of 26 individual bones called vertebrae when it is singular, and vertebrae when the amount. The lumbar vertebrae are more robust than the vertebrae of other regions because they are responsible for disagreement with the weight of the body above them and anything held or carried.
The lumbar vertebrae share the basic properties of all vertebrae. These include a body, a flat, disk part of the bone, which points to the front of the fuselage. Behind the body is a hole called foramen vertebrae, through which the spinal cord passes and which is closed by the vertebra. Two pedicles connect to the arch with the body, which are opposite two individual lamines on the turn of the arch. The vertebral arch also has three processes, in this case three small projections to which the muscles are connected. Two projections above and afterD by each side of the arch, called the superior and inferior joint processes, they form joints with the two closest vertebrae.
When the lumbar vertebrae carry more stress than other vertebral areas, they have some unique features that allow them to support the suitcase of the body. The bodies of lumbar vertebrae, which are the mass parts of all vertebrae, are wider and larger than bodies in other regions. The three protruding processes are short and dull to allow the connection of large, strong muscles. The joint processes also face different directions and provide greater stability in the lumbar region by limiting the scope of rotation.
lumbar vertebrae are marked similarly to other vertebrae in the spine column. They are marked by letter, in this case l for lumbar and number based on their order in the column. The lumbar vertebrae closest to the head is called L1 and proceeds in descending order to the lowest L5.
To identify the loinvertebrae as individual bones, we need to know how it differs from vertebrae of two areas above them, called cervical and thoracic areas. Cervical vertebrae have two holes in the arch and the thoracic vertebrae have aspects where the ribs are connected. The lumbar vertebrae do not even have characteristic and their larger, stronger bodies also identify markers.
