What are the three types of muscle tissue?

1. Skeletal, cardiac, smooth

2. Skeletal, elastic, nervous

3. Smooth, striated, cardiac

4. Cardiac, smooth, fibrous

The correct answer is: Skeletal, cardiac, smooth

The three types of muscle tissue are skeletal, cardiac, and smooth. Each of these muscle types has distinct characteristics and functions. Skeletal muscle is the type of muscle that is attached to bones and is responsible for voluntary movements of the body. This muscle type is striated in appearance, which means it has a striped look under a microscope due to the organized arrangement of its fibers. Skeletal muscles are under voluntary control, allowing for conscious movement. Cardiac muscle is found only in the heart. It is also striated but differs from skeletal muscle in that it operates involuntarily. Cardiac muscle is specialized for continuous and rhythmic contractions, which are essential for pumping blood throughout the body. It has unique features such as intercalated discs that help synchronize heart contractions. Smooth muscle is found in the walls of hollow organs, such as the intestines, blood vessels, and the bladder. This type of muscle is non-striated and operates involuntarily. Smooth muscle contractions are typically slower and can be sustained for longer periods than skeletal muscle contractions. The other answer choices include incorrect types of muscle. Elastic muscle is not recognized as a distinct type of muscle tissue; nervous tissue relates to the nervous system rather than muscle. Striated
