A throat sack was part of an Ithorian's anatomy. Their four throats were housed in this sack.
Throat sack was first mentioned in Monsters and Aliens from George Lucas, a book published in 1993. Lucasfilm employee Leland Chee, who maintains the Holocron continuity database, has indicated that information contained in the book is non-canonical. Throat sack was later made canonical with the publishing of Musings of an Ithorian on Hyperspace.
