selkärakenne
Selkärakenne refers to the spinal structure in vertebrates. It is a complex and crucial component of the skeletal system, providing support for the body, enabling movement, and protecting the spinal cord. The human spine, for instance, is composed of a series of interconnected bones called vertebrae. These vertebrae are typically divided into distinct regions: the cervical spine in the neck, the thoracic spine in the upper back, the lumbar spine in the lower back, the sacrum, and the coccyx at the base of the spine.
Between each vertebra, intervertebral discs made of cartilage act as shock absorbers and allow for flexibility.
The structure and function of the selkärakenne are essential for a wide range of biological processes. Its
