Pubic symphysis
Pubic symphysis
The Pubic symphysis (pronounced: /ˈpyuːbɪk ˈsɪmfɪsɪs/) is a midline, non-synovial joint that connects the left and right superior pubic rami.
Etymology
The term "pubic symphysis" is derived from the Latin symphysis, meaning "growing together", and pubis, referring to the pubic bone.
Anatomy
The pubic symphysis is located anterior to the urinary bladder and superior to the external genitalia. It is a cartilaginous joint, that is, it is connected by fibrocartilage. The width of the pubic symphysis at the front and above is approximately 3-5mm, but can be up to 1.5 cm following childbirth.
Function
The primary function of the pubic symphysis is to bear weight and withstand tension that is produced by the actions of the lower limbs. It also allows for slight movement to accommodate changes in the pelvis during childbirth.
