hryggsúlan

Hryggsúlan is a term used in Icelandic to refer to the vertebral column, commonly known as the spine. This complex structure is a central part of the skeletal system, providing support and protection for the spinal cord. It is composed of a series of individual bones called vertebrae, which are stacked one on top of another.

The hryggsúlan is divided into distinct regions: the cervical spine (neck), thoracic spine (upper back), lumbar spine (lower back), the sacrum, and the coccyx (tailbone). Between most of the vertebrae are intervertebral discs, which act as shock absorbers and allow for flexibility. Ligaments and muscles also surround and support the hryggsúlan, enabling movement and stability.

The primary functions of the hryggsúlan are to support the body's weight, maintain posture, and protect the delicate spinal cord, which transmits nerve signals between the brain and the rest of the body. Disorders affecting the hryggsúlan can lead to pain, stiffness, and mobility issues.
