Which of the following is a type of muscle tissue?

Smooth muscle tissue is one of the three primary types of muscle tissue, along with cardiac and skeletal muscle. Smooth muscle is found in the walls of hollow organs, such as the intestines, blood vessels, and the bladder. It plays a crucial role in involuntary movements, such as the contraction and relaxation of these organs, which regulate various bodily functions, including digestion and blood flow.

Smooth muscle is characterized by its non-striated appearance and its ability to contract without conscious control. This differentiates it from the other types of muscle tissue, which include skeletal muscle, which is striated and under voluntary control, and cardiac muscle, which is also striated but involuntary and specific to the heart.

The other options provided do not constitute muscle tissue: squamous refers to a type of epithelial cell, osseous is related to bone tissue, and fibrous pertains to connective tissue. Understanding these distinctions is essential in the study of human anatomy and physiology, as it helps clarify the roles different tissue types play in the body.
