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 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 type of muscle tissue is voluntarily controlled?
Generally, skeletal muscle is voluntarily controlled and smooth muscle is not. Some structures have a combination of both. For example, the bladder is made up of smooth muscle and consists of some skeletal muscle at the sphincter which is capable of "holding" it until you are ready.
