urinary bladder
Detrusor muscle is found in the urinary bladder.
Outer = longitudinal smooth muscle Middle= circular smooth muscle Innermost= longitudinal smooth muscle
Overactive bladder
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.
detrusor muscle
The main muscle in the bladder is called the Detrusor muscle (which is a smooth muscle). it is circular.
"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.
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.
Yes, the bladder is an organ. It's made up of multiple tissues (e.g. columnar epithelium, smooth muscle) that have a single fuction (storing and eliminating urine).
1) The detrusor muscle must contract 2) The internal urethral sphincter must open 3)The external urethral sphincter must open
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.
The sternocleidomastoid muscle is located in the neck
