The nerve roots pass through these joints to go from the spinal cord to the arms, legs and other parts of the body. These joints also allow the spine to bend and twist, and they keep the back from slipping too far forward or twisting without limits.

When we use an HTTP Proxy for an IRC or FTP connection, what does specifically happen?
