Skeletal Muscle Research Paper

The human body is made up of many types of muscles. All of the muscles work similarly and are formed similarly, but they all have their own unique characteristic about them. There are three different types of muscles in the human body: skeletal, cardiac, and smooth. All of these muscles have many similarities and many differences in relation to how they are made and what they do. All muscles work by contracting then relaxing themselves to make the human body does what it does. People tend to think about only one type of muscle though, the skeletal muscle. People don't realize that they are thinking of that type of muscle, but when people talk about their biceps or something like that that is skeletal muscle. ( Mrs. Walcott)

All muscles are made up of fibers which helps the muscle do what it is intended to do. Muscles have many characteristics that make them muscles like excitability, contractility, extensibility, and elasticity. Excitability means that the muscle is able to respond to stimuli. Contractility means that the muscles are able to shorten in length. Extensibility means that the muscle stretches when it is being pulled. Then finally elasticity means that the muscle returns to it's original shape and length after it is contracted or extended. (

The smooth muscles are referred to as muscles of the viscera. They are probably the least commonly known muscle because it is the muscle that helps food and other things like that go through your digestive system. Smooth muscles also work around many other places in the body that you are probably not even aware of. Smooth muscles are involuntary muscles so that is a big reason why most people don't even know what they are or where they are located. Smooth muscles are also a very important to the human body just like the skeletal muscles to help the body perform its daily tasks. ( Your
