What else can I help you with?
Where would you find the detrusor muscle?
Detrusor muscle is found in the urinary bladder.
The detrusor muscle is located where?
urinary bladder
Which muscle compresses the urinary bladder for micturition?
The muscle that compresses the urinary bladder during micturition is the detrusor muscle. This smooth muscle layer surrounds the bladder and contracts to expel urine from the bladder into the urethra. The contraction of the detrusor muscle is primarily controlled by the autonomic nervous system, specifically the parasympathetic division.
What muscle lines the bladder wall?
The main muscle in the bladder is called the Detrusor muscle (which is a smooth muscle). it is circular.
Does the detrusor muscle invade the inner or outer half of the muscularis propria?
The detrusor muscle, which is the smooth muscle layer of the bladder, primarily comprises the muscularis propria. It does not invade the inner or outer half of the muscularis propria, as it is a part of this layer itself. The muscularis propria consists of interwoven bundles of detrusor muscle fibers that facilitate bladder contraction. Thus, the detrusor muscle is integral to the structure of the muscularis propria rather than invading it.
Is the bladder a voluntary muscle?
The majority of the bladder is made of detrusor muscle. This muscle is told by the nervous system to contract when it expands. This is what causes the feeling of needing to urinate. In order to urinate the involuntary muscle the internal sphincter, and the voluntary muscle the external sphincter must both be opened. The detrusor muscle moves involuntarily, so the bladder would probably considered an involuntary muscle.
What are the bundles of interlaced muscular fibers in the wall of the urinary bladder comprise calle?
detrusor muscle
What triangular shaped muscle area within the bladder contracts during urination?
The detrusor muscle is the main muscle within the bladder that contracts during urination to help expel urine. It is a smooth muscle that forms a triangular shape at the base of the bladder.
What is emptying the bladder controlled by?
The micturition reflex tells you when you need to empty your bladder. This happens on average four to eight times a day. The reflex is controlled by your central nervous system. When your bladder is about half full, the stretch receptors in the walls of your bladder become active and send signals along your pelvic nerves to your spinal cord. A reflex signal is sent back to your bladder, which makes the detrusor muscle in the bladder wall contract. The contraction increases the pressure in your bladder, and this is what makes you want to pass urine. Because the external sphincter is under voluntary control, you don't urinate until you decide to relax this muscle. simple answer would be this; Sphincter muscle that surrounds the urethra.
What does Widely invasive with multiple foci of deep detrusor muscle invasion mean?
"Widely invasive with multiple foci of deep detrusor muscle invasion" refers to a type of cancer, likely bladder cancer, that has extensively spread into the detrusor muscle, which is responsible for bladder contraction. The term "multiple foci" indicates that there are several distinct areas of invasion within the muscle layer. This suggests a more aggressive disease with a higher likelihood of affecting surrounding tissues and a potentially poorer prognosis. Such findings typically necessitate more aggressive treatment approaches.
How adrenaline affects urination?
It relaxes the bladder's muscle (detrusor) and contracts the sphincter, thus preventing it's voiding. On the other hand it increases the ureters activity, facilitating urine's reach to the bladder.
What triggers the micturition response?
The micturition response is triggered by a combination of a full bladder sending sensory signals to the brain, voluntary relaxation of the external sphincter, and involuntary contraction of the bladder muscle (detrusor muscle) mediated by the parasympathetic nervous system. This process helps to empty the bladder of urine.
