SPINAL COLUMN Meaning and
Definition
-
The spinal column, also known as the vertebral column or backbone, refers to the central axis of the skeletal system in humans and other vertebrates. It is composed of a series of bones known as vertebrae stacked on top of each other. The primary function of the spinal column is to provide support, stability, and protection for the spinal cord, which is the vital component of the nervous system.
The spinal column is divided into five regions based on its curvature and anatomical features: cervical, thoracic, lumbar, sacral, and coccygeal. The cervical region consists of seven vertebrae located in the neck area, while the thoracic region consists of twelve vertebrae in the upper back. The lumbar region is comprised of five vertebrae in the lower back, followed by the sacral region consisting of five fused vertebrae that form the sacrum. Lastly, the coccygeal region, often referred to as the tailbone, consists of three to five fused vertebrae.
The spinal column not only provides structural support but also allows for movement and flexibility. Intervertebral discs, made up of fibrocartilage, are located between each vertebra, acting as shock absorbers and facilitating smooth movement. Ligaments and muscles attached to the spinal column provide additional support and aid in stabilization.
Any damage or misalignment to the spinal column can interfere with its crucial role in protecting the spinal cord and may lead to various health issues. Maintaining a proper posture, exercising, and avoiding excessive strain or trauma are essential for the optimal functioning and well-being of the spinal column.

Etymology of SPINAL COLUMN
The word "spinal" comes from the Latin word "spina", which means "thorn" or "backbone". "Column", on the other hand, is derived from the Latin word "columna", which originally meant "pillar" or "support". Therefore, the term "spinal column" refers to the supporting pillar-like structure formed by the bones of the back or backbone, which resembles the thorny structure of a plant.
