lendarhryggur

Lendarhryggur is the Icelandic word for the lumbar spine. It refers to the lower part of the vertebral column, located in the back, between the thoracic spine and the sacrum. This region consists of five vertebrae, typically denoted as L1 through L5. These vertebrae are larger and more robust than those in the thoracic region, as they bear a significant portion of the body's weight and are crucial for posture and movement.

The lumbar spine plays a vital role in allowing for flexion, extension, and lateral bending of the torso. It also provides attachment points for numerous muscles of the back and abdomen, which are essential for stability and locomotion. Due to the heavy load it carries, the lumbar spine is a common site for pain and injury. Conditions such as herniated discs, spinal stenosis, and muscle strains can affect this area, leading to discomfort and reduced mobility. Maintaining good posture, regular exercise, and proper lifting techniques are often recommended to support the health of the lendarhryggur.
