The psoas origin is a pretty interesting spot - it starts in the lumbar spine, where it attaches to the vertebrae. From there, it runs down through the pelvis and into the thigh, where it finally inserts into the femur. It's like a long, muscular highway that helps us walk, run, and dance!
But wait, it gets even more fascinating - the psoas muscle is actually two muscles in one! The psoas major and psoas minor work together to help us move our hips and legs. And, fun fact: the psoas minor is actually missing in about 40% of people - but don't worry, it doesn't seem to cause any major issues!
