Final answer:
Smooth muscle tissue surrounds the urinary bladder and is characterized as involuntary muscle with no striations and a single nucleus per cell.
Step-by-step explanation:
The muscle tissue found surrounding the urinary bladder is smooth muscle. This type of muscle tissue is also present in the walls of other hollow organs such as the intestines and stomach, as well as around passageways like blood vessels and the respiratory tract. Smooth muscle is characterized by having no visible striations, having cells with a single nucleus, being tapered at both ends, and being not under voluntary control, which is why they are referred to as involuntary muscles. Unlike skeletal muscle, which is under conscious control and is responsible for locomotion and movements we can consciously command (thus called voluntary muscles), smooth muscle functions without our conscious input, playing a crucial role in various bodily functions such as controlling the diameter of blood vessels and the movement of food through the digestive system.
