A neutral spine or good posture refers to the "three natural curves are present in a healthy spine." From the anterior/posterior view the 33 vertebrae in the spinal column should appear completely vertical. From the sagittal view, the cervical region of the spine (C1-C7) is convex anteriorly, the thoracic region (T1-T12) is convex posteriorly, and the lumbar region (L1-L5) is convex anteriorly. The sacrum (S1-S5 fused) and coccyx (on average 4 fused) rest between the pelvic bones. A neutral pelvis indicates the anterior superior iliac spines and pubic symphysis fall in the same vertical line.

Famous quotes containing the words neutral and/or spine:
“The lonely Earth amid the balls
That hurry through the eternal halls,
A makeweight flying to the void,
Supplemental asteroid,
Or compensatory spark,
Shoots across the neutral Dark.”

“Much of a man’s character will be found betokened in his backbone. I would rather feel your spine than your skull, whoever you are. A thin joist of a spine never yet upheld a full and noble soul.”
—Herman Melville (1819–1891)
