Key points
- The urinary bladder is a hollow muscular organ that stores urine and, when empty in adults, lies behind the pubic symphysis in the pelvis.
- Its main parts are the apex, body, fundus and neck, with the neck continuing into the urethra.
- The bladder wall contains a stretchable lining and the detrusor muscle, which contracts during emptying.
- Its blood vessels, lymphatic drainage and nerves connect it with the wider anatomy of the pelvis.
