What type of tissue is the urethra?

The urethra is composed of an inner epithelial lining, a spongy submucosa, a middle smooth muscle layer, and an outer fibroelastic connective-tissue layer. The spongy submucosa contains rich vascular plexus that is responsible, in part, for providing adequate urethral occlusive pressure.

How thick is the lining of the bladder?

What does connective tissue do in the bladder?

Surrounding the mucosal layer is the submucosa, a layer of connective tissue with blood vessels and nervous tissue that supports and controls the surrounding tissue layers. The visceral muscles of the muscularis layer surround the submucosa and provide the urinary bladder with its ability to expand and contract.

What relaxes the bladder?

Anticholinergic medicines help relax the muscles of the bladder. They include oxybutynin (Oxytrol, Ditropan), tolterodine (Detrol), darifenacin (Enablex), trospium (Sanctura), and solifenacin (VESIcare). Beta agonist drugs can also help relax the muscles of the bladder.

What’s a neurogenic bladder?

In neurogenic bladder, the nerves that carry messages back-and-forth between the bladder and the spinal cord and brain don’t work the way they should. Damage or changes in the nervous system and infection can cause neurogenic bladder. Treatment is aimed at preventing kidney damage.

What is the histology of urethra?

The wall of the urethra is made up of mucous, submucous and muscular layers. Its mucous membrane consist of a lining pseudostratified columnar epithelium, mainly transitional epithelium on the short part adjoining the urinary bladder and stratified squamous epithelium on the part near the external urethral orifice.
