Hi everybody, I'm translating a text of Biology about the black widow spider, and it appears the word "ampullate" many times, but I don't know what it means.

For example, "Major ampullate fibers obtained from anaesthetized spiders ...."

I would be very grateful, thanks.

Bye. :confused:

    Webster's new world dictionary:

    ampulla: ...3) anatomy- a sac or dilated part of a tube or canal, as of a milk duct in a mammary gland.

    I would take this to mean that an ampullate fiber is a fiber that is hollow and has a widened section.

    Hope this helped.
