Tendinous arch of the pelvic fascia
Puboprostatic/pubovesical ligament
Part of the UB covered by peritoneum
Superior surface only
In males, separates the UB from rectum
Rectovesical septum
Supplies the anterosuperior part of the UB
Superior vesical a
Supplies the fundus and neck of the UB in males? Females?
Males: inferior vesical a
Females: vaginal a
Sympathetic fibers that supplies the bladder comes from
Hypogastric Plexus
Parasympathetic fibers that innervate the bladder comes from
Sacral spinal cord through pelvic splanchnic nerves and inferior hypogastric plexus
The UB is separated to the rectum by what structures?
Seminal vesicles

External iliac nodes
Lymph drainage of the posterior part of the bladder
Iliac nodes
Bladder: considered as the filling nerve
