Where would you find the detrusor muscle?
Detrusor muscle is found in the urinary bladder.
The detrusor muscle is located where?
urinary bladder
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.
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 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.
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.
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).
Is your bladder a muscle?
Urinary bladder mainly contains two types of musces 1. Smooth muscles, forming the wall of the bladder ( Detrusor muscle ) and the internal urethral sphincter ( which controls the flow of urine which is involuntary ), and 2. Skeletal muscle, which forms the external urethral sphicter with which we can control the flow of urine.. ( voluntary control of flow )
What is the muscular portion of the urinary bladder called?
The muscular bag inside a body is called the stomach. It helps the digestive system to store food before it is processed into other forms.
Does sympathetic system causes bladder wall relaxation?
Yes it does relax. When the detrusor muscle, part of the bladder wall, constricts, you urinate. In a high energy situation, when sympathetic stimulation is occurring, you wouldn't want to urinate, so the wall must relax.
Why does it hurt when you hold in your urine?
Because your bladder is only designed to hold so much. Once it reaches a point where the tissues are stretched too far, the nerve endings in the bladder send pain signals to your brain. The muscle that is part of the layered bladder wall, the detrusor muscle, starts to contract, increasing the pressure. At that point, break off what you're doing and go!
