What are the three types of muscles and what is movement for each muscle?

There are three main types of muscles in the human body: skeletal, smooth, and cardiac muscle. Each type of muscle has a different structure and function.

Skeletal muscle is attached to bones and is responsible for voluntary movement, such as walking, running, and lifting objects. Skeletal muscles are striated, which means they have a banded appearance under a microscope. They are also multinucleated, meaning they have more than one nucleus per cell.

Smooth muscle is found in the walls of hollow organs, such as the stomach, intestines, and blood vessels. Smooth muscle is responsible for involuntary movement, such as digestion and the regulation of blood pressure. Smooth muscles are not striated and are uninucleated, meaning they have only one nucleus per cell.

Cardiac muscle is found only in the heart. Cardiac muscle is responsible for the pumping action of the heart, which circulates blood throughout the body. Cardiac muscle is striated and uninucleated.

Here is a table summarizing the three types of muscles:

| Muscle Type | Structure | Function | Location |

|---|---|---|---|

| Skeletal muscle | Striated, multinucleated | Voluntary movement | Attached to bones |

| Smooth muscle | Not striated, uninucleated | Involuntary movement | Walls of hollow organs |

| Cardiac muscle | Striated, uninucleated | Pumping action of the heart | Heart |
