Fused-Plate Spinal Segments
Kneel on all fours. Detect which spinal segments refuse the gradient — segments that insist on moving at the same rate as their neighbors, behaving as a fused plate rather than a distinct stage.
Full Lesson Notes
Complete Practice
Kneel on all fours. Borrow fractional distillation: the column separates fast volatile components from slow heavy ones along a temperature gradient. Construct a movement gradient along the spine by initiating a small wave at the sacrum and propagating it cephalad while gradually decreasing the velocity at each segment, so the head moves last and slowest. Detect which spinal segments refuse the gradient — segments that insist on moving at the same rate as their neighbors, behaving as a fused plate rather than a distinct stage. Note them; they are the body's azeotropes for this motion.
