lactiferous ampulla -->
lactiferous sinus
medical dictionary

A circumscribed spindle-shaped dilation of the lactiferous duct just before it enters the nipple. In nursing mothers this dilatation stores a droplet of milk which is expressed by compression as the infant begins to suckle; this is thought to encourage continual suckling while the let-down reflex ensues.

Synonyms: sinus lactiferi, ampulla lactifera, ampulla of milk duct, lactiferous ampulla.
