APPLIED RADIOLOGICAL ANATOMY

Detailed explanation-1: -The L1 vertebra is the topmost section of the lumbar spinal column. This section of the spine contains a portion of the spinal cord. Injuries to the L1 spine can affect hip flexion, cause paraplegia, loss of bowel/bladder control, and/or numbness in the legs.

Detailed explanation-2: -The L1 vertebra (1st lumbar vertebra) is the smallest and most superior of the lumbar vertebrae. As the first vertebra in the lumbar region, the L1 vertebra bears the weight of the upper body and acts as a transition between the thoracic and lumbar vertebrae.

Detailed explanation-3: -Compression fractures of the spine usually occur at the bottom part of the thoracic spine (T11 and T12) and the first vertebra of the lumbar spine (L1). Compression fractures of the spine generally occur from too much pressure on the vertebral body.

Detailed explanation-4: -Lumbar spinal cord injury L1-L5 Lumbar level injuries result in paralysis or weakness of the legs (paraplegia). Loss of physical sensation, bowel, bladder, and sexual dysfunction can occur. However, shoulders, arms, and hand function are usually unaffected.

Detailed explanation-5: -The lumbar vertebrae are five in number and desginated as vertebrae L1-L5. They are primarily responsible for bearing the weight of the upper body (and permitting movement) and consequently represent the largest individual segments of the vertebral column.
