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 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.
