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 5 examples of voluntary and involuntary muscles?
Voluntary muscles: biceps, quadriceps, deltoids, abdominals, trapezius. Involuntary muscles: heart muscle (cardiac muscle), smooth muscle in the digestive tract, diaphragm, bladder muscles, iris muscles.
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.
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 )
Is the neck a voluntary or involuntary muscle?
neck muscle is voluntary muscle i think this is correct
What type of muscle is involuntary and found in your stomachintestines and bladder?
The type of muscle that is involuntary and found in the stomach, intestines, and bladder is known as smooth muscle. Unlike skeletal muscle, which is under voluntary control, smooth muscle functions automatically to facilitate processes such as digestion and the movement of urine. It is characterized by its non-striated appearance and is controlled by the autonomic nervous system.
What structures rely on muscle action for the movemnvt of urine?
The movement of urine primarily relies on the action of smooth muscle in the walls of the ureters and the bladder. The ureters use peristaltic contractions to transport urine from the kidneys to the bladder. Once the bladder fills, its smooth muscle, known as the detrusor muscle, contracts to facilitate urination. Additionally, the external urethral sphincter, composed of skeletal muscle, allows for voluntary control over the release of urine.
What is the action involved in micturition?
Micturition is the process of expelling urine from the bladder through the urethra. It involves a series of coordinated actions, including the relaxation of the internal and external urethral sphincters and the contraction of the bladder's detrusor muscle. This process is typically initiated when the bladder fills and stretches, signaling the brain to trigger the urge to urinate. Voluntary control allows individuals to decide when to release urine, making it a complex interplay of involuntary and voluntary muscle actions.
What is a voluntary muscle?
Voluntary muscle is the one we can control. For example, the skeletal 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 are the differences between cardiac smooth and voluntary muscles?
muscle tissue is either voluntary or involuntary. The heart is an involuntary muscle you don't consciously control this muscle. Smooth muscles are also involuntary and are found in the internal organs such as the bladder, stomach they churn food constrict blood vessels ect...thing you don't have to think about.
Is my calf voluntary or involuntary?

Can a smooth muscle be voluntary?
yes it is.....
