Lumbar spine

Refers to the lower back, where the spine curves inward toward the abdomen. It starts about five or six inches below the shoulder blades, and connects with the thoracic spine at the top and extends downward to the sacral spine.

“Lumbar” is derived from the Latin word “lumbus,” meaning lion, and the lumbar spine earns its name. It is built for both power and flexibility - lifting, twisting, and bending.
