Your lumbar spine is the lower back region of your spinal column or backbone. It consists of five bones (L1-L5). Other structures in or around your lumbar spine are your intervertebral disks, spinal cord and nerves, muscles, tendons and ligaments.
The spine’s four sections, from top to bottom, are the cervical (neck), thoracic (abdomen,) lumbar (lower back), and sacral (toward tailbone). Throughout the spine, intervertebral discs made...
Your spine is the long column of bones that extend from your neck to your lower back. Your spine starts at the base of your skull (head bone) and ends at your tailbone, a part of your pelvis (the large bony structure between your abdomen and legs).
The lumbar spine connects with the thoracic spine above at the thoracolumbar junction and the sacral spine below at the lumbosacral joint. The lumbar motion segments may be affected by congenital (birth-related), degenerative, traumatic, or inflammatory disorders. See Lower Back Pain Symptoms, Diagnosis, and Treatment.
Understanding the anatomy of your lower spine can help you communicate more effectively with the medical professionals who treat your lower back pain. Here is a description of useful anatomical landmarks.
The lumbar spine makes up the the lower end of the spinal column. It consists of 5 lumbar vertebra that are numbered 1 through 5 from top to bottom i.e. L1, L2, L3, L4, and L5. The L5 vertebra is connected to the top of the sacrum (named the S1 segment) through an intervertebral disc.
The lumbar spine is the third and lowermost part of the spinal column, consisting of 5 lumbar vertebrae, L1-L5. They are found in the lower back, supporting the body’s weight and providing flexibility and movement. These are the largest among all the vertebrae found in the spine.
The lumbar vertebrae are perhaps most easily defined by their stout and think vertebral bodies; they are relatively large, wider laterally compared to anteroposteriorly and thicker in its anterior half compared to posterior (which contributes to the ).
The lumbar vertebrae consist of five individual cylindrical bones that form the spine in the lower back. These vertebrae carry all of the upper body's weight while providing flexibility and movement to the trunk region.
Overview of the location of the lumbar vertebrae. The lumbar spine is the third region of the vertebral column, located in the lower back between the thoracic and sacral vertebral segments. It is made up of five distinct vertebrae, which are the largest of the vertebral column.
