<br><br>Let's first look at the vertebral column and make sure we are familiar with its natural curves in anatomical position. Anatomical position is with a subject standing, feet together at the heels, arms at the sides with the hands palms forward. In this position, viewed from the side, the spine has a sideways sinusoidal (S- curve, "in and out") appearance from cervical to coccygeal areas.
