All are true about urinary bladder except –
**Core Concept**
The urinary bladder is a hollow, muscular organ that stores urine from the kidneys until it is expelled from the body. It is a part of the lower urinary tract, which also includes the ureters, urethra, and pelvic floor muscles.
**Why the Correct Answer is Right**
The correct answer is a statement that is true about the urinary bladder. The bladder's muscular layer, known as the detrusor muscle, contracts to expel urine from the bladder through the urethra. This process is controlled by the autonomic nervous system, which includes the sympathetic and parasympathetic nervous systems. The parasympathetic nervous system, specifically the sacral nerve roots, stimulates bladder contraction, while the sympathetic nervous system inhibits it.
