pubic symphysis[′pyü·bik ′sim·fə·səs]
the union of the left and right pubic bones by a cartilaginous plate, which has a slitlike cavity filled with synovial fluid.
The pubic symphysis is secured by anterior, posterior, and superior public ligaments. During pregnancy, the pubic symphysis becomes larger and more extensible, facilitating childbirth.
