Selkäd

Selkäd is a term that refers to the spine or vertebral column in Finnish. This complex structure is composed of individual bones called vertebrae, which are stacked on top of each other to form a protective column for the spinal cord. The spine is crucial for providing structural support to the body, allowing for a wide range of movement, and protecting the delicate nerves that transmit signals between the brain and the rest of the body.

The human spine is typically divided into several regions. The cervical spine is located in the neck and consists of seven vertebrae. Below this is the thoracic spine, comprising twelve vertebrae that are attached to the ribs. The lumbar spine, in the lower back, has five vertebrae. Finally, at the base of the spine are the sacrum, a fused bone, and the coccyx, commonly known as the tailbone.

Discs made of cartilage are located between each vertebra, acting as shock absorbers and allowing for flexibility. Ligaments and muscles also play a vital role in supporting and stabilizing the spine. Conditions affecting the selkäd can range from minor strains to severe injuries and degenerative diseases, impacting mobility and overall health. Understanding the structure and function of the selkäd is fundamental to comprehending human anatomy and biomechanics.
