Definition
Lumbus is a term referring to the loin, specifically the region of the body between the ribs and the pelvis on either side of the spinal column. Think of it as the lower back area, important for posture and movement. It supports the spine and connects the upper and lower body. It's a more formal, anatomical term, almost like saying 'thorax' instead of 'chest.' It is crucial for stability and flexibility. πͺ
