Selkäydinten

Selkäydinten is a Finnish term that translates to "spinal cords" in English. In a biological context, it refers to the central nervous system's structure that extends from the brainstem down the back. This vital component is responsible for transmitting neural signals between the brain and the rest of the body. It is protected by the vertebral column, or spine. The spinal cord is a complex network of nerves that facilitates voluntary movements, sensory perception, and involuntary reflexes. Damage to the spinal cord can result in varying degrees of paralysis or loss of sensation, depending on the location and severity of the injury. The term can also be used metaphorically to describe the core or essential part of something, analogous to how the spinal cord is central to bodily function. This metaphorical usage highlights the idea of a fundamental support or organizing principle.
