Microscopic Photos of Urinary System Tissue Slides 3 years, 11 months ago Under the epithelium is a thick, fibroelastic lamina propria.
This mucosa (epithelium and lamina propria) serves as a barrier.
There are no mucosal or submucosal glands present, as well as no submucosa.Outside the mucosa, there is a layer of smooth muscle:
The upper two-thirds of the body is made up of two layers of smooth muscle: an inner longitudinal layer and an outer circular layer.
The lower third of the body is made up of three layers of smooth muscle: inner longitudinal, middle circular, and outer longitudinal.
Peristalsis squeezes urine into the bladder.
The outer adventitial layer is made up of fibroelastic connective tissue that contains blood vessels, lymphatics, and nerves.
When the bladder is full, mucosal folds help to protect against urine reflux.
