There is some disagreement about the ability of a state to rescind an amendment ratification prior to full ratification.

The Intercostal Muscles. These muscles are found between the ribs, and there are two kinds: the internal and external intercostals. The internal intercostal muscles (in the inside of the ribcase) extend from the front of the ribs, and go around back, past the bend in the ribs.
The intercostal muscles are a group of intrinsic chest wall muscles occupying the intercostal spaces.he contraction of the external intercostal muscles causes an elevation of the ribs (inspiratory breathing muscles) whereas both the internal and innermost intercostal muscles lower the ribs (expiratory breathing muscles).
