- The bladder is where urine is stored before being expelled by the body through the micturition reflex.
- Without a bladder urinary continence would be impossible.
Anatomy
- It is a hollow, muscular organ
- It is divided for descriptive purposes into three parts
- Cranial Pole
- Intermediate body
- Caudal neck
- Its size and posistion are determined by how full it is.
- When empty the bladder wall is wrinkled and thicker
- When full and distended the folds dissapear and the wall appears thinner
- The paired uteric folds are visible even when the bladder is full.
- They extend from the ureteral opening to the neck of the bladder
- Here they merge
- Forms the urethral crest - continues into the urethra
The Ligaments of the Bladder
- Two lateral ligaments
- Insert in the dorsal abdominal wall
- Within them are the residual umbilical vessels
- Median ligament
- Connects the bladder to pelvic floor and linea alba
