The movement of the back is limited to the spaces between the vertebrae. In bending
backward and forward the expansion or contraction occurs in the waist or lumbar region.
In bending sideways there is no movement in the entire length of the spine.
With the movement of the shoulder girdle the shoulder blades rotate on the cage.
Them are twenty-six vertebrae composing the entire spine, the first seven belong to the
neck, the eight will give you the line of the shoulders. The lower tip of the triangular shape
of the shoulder blade is about half way down on the cage. In profile keep the neck concave.
The back convex, the region between the end of the cage and the top of the hips concave.
After blocking in the head, suggest the line of movement with the spine and then place the
cage and pelvis on it.
In modelling the back, keep in mind a concept of
a large peach with
a recession in the center for the vertebrae.
