bladderSee URINARY BLADDER.
bladdera hollow muscular bag situated in the lower abdominal cavity of mammals serving as a reservoir for urine from the kidneys. The bladder is composed of an internal epithelium surrounded by a coat of smooth muscle running in both circular and longitudinal directions, contraction of which causes complete collapse of the bag-like shape. The flow of urine down the URETERS from kidneys to the bladder is continuous, the amount depending on body fluid levels. When the bladder is empty the opening to the outside is closed by an internal SPHINCTER of smooth muscle which, like the bladder muscle, is controlled by the AUTONOMIC NERVOUS SYSTEM. When full, the internal sphincter relaxes under nervous control and urine enters the URETHRA (the duct to the outside), but is prevented from being voided by contraction of an external sphincter of striated muscle. Regulation of the sphincter (and thus or urine release or ‘micturition’) is under voluntary nervous control.
