Final answer:
Smooth muscle tissue is present in the walls of hollow organs such as the urinary bladder and stomach, as well as in passages like blood vessels and the respiratory tract. It is involuntarily controlled and has a single nucleus per cell.
Step-by-step explanation:
Smooth muscle tissue is found in the walls of various hollow organs and passageways in the body. These include the stomach, intestines, urinary bladder, and in the respiratory, digestive, and reproductive tracts. This type of muscle is characterized by its lack of striations, making it non-striated, and its control is involuntary, regulated by the autonomic nervous system.
Smooth muscle cells have a single nucleus, are tapered at both ends, and do not operate under voluntary control, distinguishing them from skeletal muscle. Additionally, in specific areas like large blood vessels and the eyes, smooth muscle cells function individually due to the lack of electrical coupling through gap junctions, responding solely to autonomic nerve stimuli or hormones.
