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.
