Does the bladder contract or relax during urination?
A
Contract
B
Relax
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -The primary function of the detrusor muscle is to contract during urination to push the urine out of the bladder and into the urethra. The detrusor muscle will relax to allow the storage of urine in the urinary bladder.

Detailed explanation-2: -Medications that relax the bladder can be helpful for relieving symptoms of overactive bladder and reducing episodes of urge incontinence. These drugs include: Tolterodine (Detrol) Oxybutynin, which can be taken as a pill (Ditropan XL) or used as a skin patch (Oxytrol) or gel (Gelnique)

Detailed explanation-3: -When your bladder is not full, the bladder is relaxed. With a healthy bladder, signals in your brain let you know that your bladder is getting full or is full, but you can wait to go to the bathroom. With OAB, you can’t wait. You feel a sudden, urgent need to go. This can happen even if your bladder isn’t full.

Detailed explanation-4: -The detrusor smooth muscle is the main muscle component of the urinary bladder wall. Its ability to contract over a large length interval and to relax determines the bladder function during filling and micturition.
