Alternatively, in some old regional dialects, it represents a popular verb form derived from 'a ampula' (to bulge or structurally inflate).
• Ampulliform — Having the shape of an ampoule or a small vial; swollen at the base or in the central portion and structurally narrowed toward the extremities.
