The sacrum is located just below the lumbar vertebrae, forming the base of the spine and the center of the pelvis.
In more detail:
-
Location within the Spine: The sacrum sits at the bottom of the spine, directly inferior (below) to the lumbar vertebrae (the lower back). It's the part of the spine that connects to the pelvis.
-
Formation: It is formed from five fused sacral vertebrae. These segments fuse together during development.
-
Function: The sacrum provides support for the upper body, transmitting weight to the pelvis and legs. It also articulates with the hip bones to form the sacroiliac joints, crucial for stability and movement.
Therefore, when considering the location of the sacrum, remember it's the triangular bone at the base of your spine, connecting it to your pelvis.
