Overactive bladder
Detrusor muscle is found in the urinary bladder.
urinary bladder
The main muscle in the bladder is called the Detrusor muscle (which is a smooth muscle). it is circular.
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 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.
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.
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 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.
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).
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 )
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.
