Does the urinary bladder contain detrusor muscle?
Does the urinary bladder contain detrusor muscle?
The musculature of the bladder plays a key role in the storage and emptying of urine. In order to contract during micturition, the bladder wall contains specialised smooth muscle – known as detrusor muscle.
Which layer of the urinary bladder is made of the detrusor muscle?
The visceral muscles of the muscularis layer surround the submucosa and provide the urinary bladder with its ability to expand and contract. The muscularis is commonly referred to as the detrusor muscle and contracts during urination to expel urine from the body.
What happens to the detrusor muscle of the bladder to signal the bladder is filling up?
During the filling phase, the detrusor muscle relaxes to allow gradual expansion of the bladder while the urethral sphincter closes to prevent urine leaking.
What is bladder detrusor muscle?
The primary function of the detrusor muscle is to contract during urination to push the urine out of the bladder and into the urethra. The detrusor muscle will relax to allow the storage of urine in the urinary bladder.
What nerve is responsible for bladder control?
The lower urinary tract is innervated by 3 sets of peripheral nerves: pelvic parasympathetic nerves, which arise at the sacral level of the spinal cord, excite the bladder, and relax the urethra; lumbar sympathetic nerves, which inhibit the bladder body and excite the bladder base and urethra; and pudendal nerves.
Is the urinary bladder in the abdominal cavity?
The bladder is a subperitoneal, hollow muscular organ that acts as a reservoir for urine. The bladder is located in the lesser pelvis when empty and extends into the abdominal cavity when full. In children, the bladder is located in the abdomen and does not completely descend into the pelvis until puberty.

What kind of muscle is the detrusor made of?
The detrusor muscle is a layer of the bladder wall made of smooth muscle fibers that are arranged in spiral, longitudinal, and circular bundles.
How are the urethral sphincter and detrusor muscles related?
Related are the urethral sphincter muscles which envelop the urethra to control the flow of urine when they contract. The fibers of the detrusor muscle arise from the posterior surface of the body of the pubis in both sexes (musculi pubovesicales), and in the male from the adjacent part of the prostate.
What causes a hernia of the detrusor muscle?
The mucosa of the urinary bladder may herniate through the detrusor muscle. This is most often an acquired condition due to high pressure in the urinary bladder, damage, or existing connective tissue disorders. ^ Stoffel, JT (September 2017).
