A receptionist is an employee who typically works at a larger company. He or she normally is the first person a visitor or customer may encounter at the site. Receptionists typically screen incoming phone calls, while taking and distributing messages to appropriate parties.
A retrolisthesis is an acute, degenerative, or congenital condition in which a vertebra in the spine becomes displaced and moves backward. In most cases, retrolisthesis occurs when a soft disc that separates and cushions vertebrae either deteriorates or ruptures.
The backward displacement involved with retrolisthesis is less common, but still occurs in considerable frequency among people with degenerative disorders. Arthritis is a leading cause of retrolisthesis in older people, which leads to deterioration of disc tissue. Severe back injuries and congenital spine defects can also result in vertebral slippage. Retrolisthesis is most likely to affect a bone in the uppermost section of the spine, called the cervical region.
