SACRAL VERTEBRA Meaning and
Definition
-
A sacral vertebra, also known as the sacrum, is a bony structure that forms the base of the vertebral column in humans and some animals. It is positioned between the lumbar vertebrae and the coccyx and is typically comprised of five fused vertebrae (S1 to S5) in adults. Its primary function is to provide stability and support to the pelvic girdle and to transmit the weight of the upper body to the lower limbs.
The sacral vertebrae are uniquely designed and specialized to accommodate and protect vital pelvic organs, including the reproductive, urinary, and digestive systems. They are larger and more robust than the other vertebrae to bear heavy loads and maintain stability during movements. The sacrum is also crucial for maintaining the skull's position and aligning the spinal column.
One distinctive feature of the sacral vertebrae is the presence of sacral foramina, which are openings on each side that allow for the passage of sacral nerves and blood vessels. Additionally, the sacrum forms the back of the pelvic cavity, connecting with the ilium bones on either side to create the sacroiliac joints.
Overall, the sacral vertebrae play a pivotal role in supporting the weight of the body, aiding in movement and maintaining the structural integrity of the pelvis and vertebral column.

Etymology of SACRAL VERTEBRA
The word "sacral" comes from the Latin term "sacrum", which means "sacred" or "holy". In ancient Roman religious customs, the sacrum referred to the sacred bone that was believed to house the divine essence. Over time, the term "sacrum" began to be used in anatomical descriptions to describe the triangular bone located at the base of the spine, formed by the fusion of several vertebrae.
The word "vertebra" comes from the Latin term "vertere", meaning "to turn". In anatomy, a vertebra refers to one of the individual bones that make up the spinal column or backbone. These bones are responsible for providing support, protecting the spinal cord, and allowing movement of the spine.
