What it is and what it does
The urinary bladder lies in the caudal abdomen, at the border with the pelvis: it appears both among the abdominal viscera and among the pelvic ones. In a quadruped, the weight of the urine pulls it cranially, into the abdomen, away from the urethra, and when empty it draws back toward the pelvic inlet. It is held by the median ligament and the lateral ligaments; the urethra leaves from its neck.
Worth remembering
In a quadruped, the weight of the urine pulls it forward, into the abdomen; when empty, it draws back toward the pelvis.
Names
- Latin term: vesica urinaria.

In the atlas lessons
The organs: where they sit, from neck to pelvis (5 min):
Caudally: the urinary bladder sits in the caudal abdomen, toward the pelvic inlet; in the male, the prostate surrounds the urethra just past the neck of the bladder; the rectum passes dorsal to them.
