If you’ve ever experienced lower back pain, visited a physiotherapist, or studied basic anatomy, you’ve probably come across the term “sacrum.” But what exactly does it mean? For many people, the word sounds technical or confusing. Some think it’s just another name for the spine, while others assume it’s a muscle or joint. In reality, the sacrum plays a much bigger role in your body than most people realize. Understanding the sacrum meaning can help you make sense of posture issues, back pain, and even how your body balances itself while walking or sitting.
Let’s break it down in a clear, practical way.
Sacrum Meaning – Quick Definition
The sacrum is a triangular bone located at the base of your spine, just above your tailbone (coccyx).
Simple Explanation:
- It connects your spine to your pelvis
