What else can I help you with?
The detrusor muscle is located where?
urinary bladder
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.
Detrusor muscle what are the 3 layers?
Outer = longitudinal smooth muscle Middle= circular smooth muscle Innermost= longitudinal smooth muscle
Which condition occurs when the detrusor muscle in the wall of the bladder is too active?
Overactive bladder
What are the bundles of interlaced muscular fibers in the wall of the urinary bladder comprise calle?
detrusor muscle
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.
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.
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.
Which organ does the the bladder belong to?
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).
What happens for micturition to occur?
1) The detrusor muscle must contract 2) The internal urethral sphincter must open 3)The external urethral sphincter must open
Would you expect to find a muscle in a plant?
no. muscle is animal tissue
Which tissue type would you find contractile proteins?
muscle tissue
