East Antarctica (mostly in the Eastern Hemisphere) is the much larger generally oval region of Antarctica, stretching from around 60 degrees W latitude eastward to 160 E latitude, south of Africa, Asia, the Indian ocean, and Australia. East Antarctica is almost entirely covered by an ice sheet, and includes the South Pole.
On the other side of the Transantarctic Mountains is West Antarctica, the locations of the Ross, Ronne, and Larsen Ice Shelves, and the Antarctic Peninsula that stretches toward South America.
You may be thinking of the Trans-Antarctic mountain range that separates East and West Antarctica.
There is, however, only one 'region' on Antarctica, the Antarctic polar desert region.
