Getting Down With The Lumbar Spine Anatomy
You have to know the wonders that pertain to lumbar spine anatomy
. Because of the spine, we are able to do incredible things. The spine gives the body its framework and the strength it needs during activities. If an accident happens or an abnormality occurs along the spine, detrimental effects may ensue. For instance, damage to the lumbar spine area can potentially lead to incontinence and abnormal bowel control. This is the main reason that the health of our spine should be sustained.
Overview of the Lumbar Spine Anatomy
The spinal column is composed of 24 vertebrae and is categorized according to their location. The first 7 vertebrae are categorized as the cervical region, the middle 12 vertebrae are the thoracic region, and the last 5 vertebrae are the lumbar region. The lumbar spine anatomy is composed of the following:
- Vertebral body
- Vertebral arch
- Vertebral foramen
Each vertebra of the lumbar spine is unique from each other. The vertebrae are designated with the name L1-L5, with the L1 as the nearest vertebra to the skull. The general trend is that the farther the vertebra from the skull, the larger it gets. Since the lumbar spine anatomy
is the farthest region, its vertebral body is large. The vertebral body of the lumbar bones is large from side to side compared to its width. The front end of lumbar spine is thinner than the back end. The pedicles of the lumbar spine
are condensed and strong. The lamina is also sturdy and broad in size and connects the spinous process to the pedicles.
Abnormality of the Lumbar Spine Anatomy and its Effect
Any impairment that occurs along the spine has corresponding consequences. For instance, damage to the cervical region of the spine will affect swallowing. Damage to the thoracic region will result to difficulty of breathing. This happens because the spinal column houses the spinal cord which is actually an extension of the brain. If there would be an abnormality in the spinal column, it might irritate, compress, and pinch the nerve endings and nerve roots adjacent to it.
The first lumbar vertebra (L1) is almost at the level of the ninth rib. Impairment of the L1 could affect the function of the pylorus of the stomach which inhibits regurgitation of the stomach content to the esophagus. Damage to the L5 could result to spondylolysis and spondylolisthesis.
Summary of the Anatomy of Lumbar Spine
There is no denying that lumbar spine anatomy
is truly a wonder of nature. Its structure is meticulously designed from the molecular scale to its size as a whole. As a part of the spinal column, lumbar spine gives the body framework, movement, balance, and support. One of the greatest functions of the lumbar spine is for protection of the spinal cord. If there would be a single impairment of the lumbar spine or any part of the spinal cord, long-term and permanent damage may happen.
These are just some of the basic knowledge that you should know about the spinal column. The lumbar spine anatomy should be studied and get acquainted with.
