Ländkotorna

Ländkotorna, also known as lumbar vertebrae, are the five vertebrae located in the lower back, between the thoracic vertebrae and the sacrum. They are the largest and strongest vertebrae in the spinal column, designed to bear the majority of the body's weight and withstand significant stress. Each lumbar vertebra consists of a vertebral body, a vertebral arch, and several processes. The vertebral body is the weight-bearing part, while the vertebral arch encloses the spinal canal, which contains the spinal cord. The processes serve as attachment points for muscles and ligaments.

The lumbar spine plays a crucial role in movement, allowing for bending, twisting, and extension of the torso. The intervertebral discs, which are located between each lumbar vertebra, act as shock absorbers and allow for flexibility. Lumbar vertebrae are susceptible to various conditions, including herniated discs, spinal stenosis, and degenerative disc disease, often resulting in lower back pain. The curvature of the lumbar spine, known as lordosis, is a natural inward curve that helps distribute weight and maintain balance. This curvature can be exaggerated or flattened, leading to postural issues and pain. Regular exercise, proper posture, and maintaining a healthy weight are important for supporting the health of the ländkotorna.
