selkäranganosien

Selkäranganosien is a Finnish term that translates to "parts of the spine" or "spinal segments." It refers to the individual components that make up the vertebral column, also known as the spine. The spine is a complex structure composed of a series of bones called vertebrae, which are stacked one on top of another. These vertebrae protect the spinal cord, which is a crucial part of the central nervous system.

The spine is typically divided into several distinct regions. The cervical spine, located in the neck, consists of seven vertebrae. Below this is the thoracic spine, comprising twelve vertebrae, each articulating with a pair of ribs. The lumbar spine, in the lower back, has five vertebrae. Following the lumbar spine are the sacrum, a fused structure of five vertebrae, and the coccyx, commonly known as the tailbone, which is usually composed of four fused vertebrae.

Each vertebra in the spine generally shares a similar structure, including a vertebral body, a vertebral arch, and several processes that serve as attachment points for muscles and ligaments. Between most vertebrae are intervertebral discs, which act as shock absorbers and allow for movement. The collective arrangement and function of these selkäranganosien are essential for posture, mobility, and the protection of the vital spinal cord. Issues or damage to any of these parts can lead to pain and functional limitations.
