APPLIED RADIOLOGICAL ANATOMY

Detailed explanation-1: -The wall of the bladder is comprised of smooth muscle fibers oriented in multiple different directions. These smooth muscle fibers are collectively known as the detrusor muscle .

Detailed explanation-2: -Bladder smooth muscle fibers have a fusiform shape, are 300-400 m in length, are of the single unit type, and have a greater ratio of actin to myosin and a larger length-tension curve than striated muscle.

Detailed explanation-3: -Muscularis propria, also known as the detrusor muscle, consists of three sublayers: inner longitudinal, middle circular, and outer longitudinal. These sublayers are well-defined around the neck of the urinary bladder but are randomly aligned with the rest of the bladder wall.
