obelisk (sh) and ampulla lactifera (medicine)


obelisk (sh)




Tapered four-sided pillar, originally erected in pairs at the entrance to ancient Egyptian temples.

The Egyptian obelisk was carved from a single piece of stone, usually granite, and embellished with hieroglyphics. It was wider at its square or rectangular base than at its pyramidal top, and could be over 100 ft (30 m) high. During the Roman empire, many obelisks were transported from Egypt to Italy. A well-known modern obelisk is the Washington Monument.


ampulla lactifera (medicine)


ampulla lactifera -->
lactiferous sinus


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.

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