The term Generation X has been used at various times throughout history to describe alienated youth. In the 1950s, Hungarian photographer Robert Capa used Generation X as the title for a photo-essay about young men and women growing up immediately following the Second World War. In 1976, English musician Billy Idol used the moniker as the name for a punk rock band.
An atlas is defined as a collection of various maps of the Earth or a specific region of the Earth such as the United States or Europe.
These two vertebrae are the reason your neck can move in so many directions. The atlas is the first cervical vertebra-the one that sits between the skull and the rest of the spine. The atlas does not have a vertebral body, but it does have a thick forward (anterior) arch and a thin back (posterior) arch with two prominent sideways masses.
