Verified step by step guidance
1
Step 1: Understand the characteristics of the three types of muscle tissue: skeletal, cardiac, and smooth muscle. Skeletal muscle is striated and voluntary, cardiac muscle is striated and involuntary, and smooth muscle is non-striated and involuntary.
Step 2: Focus on the key terms in the question: 'non-striated' and 'involuntary.' This means the muscle tissue does not have visible striations under a microscope and is not under conscious control.
Step 3: Eliminate options that do not match the description. Skeletal muscle is striated and voluntary, so it does not fit. Cardiac muscle is striated and involuntary, so it also does not fit.
Step 4: Identify smooth muscle as the correct answer because it is non-striated and involuntary. Smooth muscle is found in the walls of hollow organs like the intestines, blood vessels, and bladder.
Step 5: Review the function of smooth muscle to reinforce understanding. Smooth muscle contracts to move substances through the body, such as food through the digestive tract or blood through vessels, without conscious control.
