Basics of the Muscular System

The muscular system, is a very important system in a human. It provides movement through your body, and pretty much, is how you push and pull things effectively. There are several types of muscles. These types include skeletal, smooth, and cardiac muscle. The cardiac muscles are in charge of pumping blood through your body, and the skeletal muscles contract and relax along your bones, making it so you can do many different movements by supplying strength throughout your bones, such as moving your legs, arms, torso and neck. These are also called voluntary muscles, because these are the only parts of your body you have control over. These are the different types of muscles or organs in the muscular system, as well as the function of the system

Interaction with other systems
The muscular system works closely with the nervous system. This is because your muscles receive messages from your brain, which travel down to your muscles to perform actions. This system is called the autonomic nervous system. Even though this true, sometimes you don't even have to think before you do a movement. These types of movements are are known as reflexes. An example of the is if a ball is coming towards you, and you hear it coming, you will mostly probably automatically move out of the way. some people have a lot better reflexes than others, and that is because their muscles have more experience with that type of stuff, so their muscles were trained to act on their own.

Analogy

I believe that the muscular system can be compared to a light switch. It might not make much sense right now, but let me explain. See, the muscular systems voluntary and involuntary muscles can be compared to the on, and off functions of a light switch. The involuntary will always be "off" as far as your nervous system can see it. This is the exact opposite for the voluntary muscles. For the voluntary muscles the nervous thinks the switch is always flipped on. Also, the light or action responding to the switch, is as if you were to preform that action. This is why I think that the muscular system can be compared to a light switch. Wait a second, I just thought of something. Don't you think that a remote control is more like an analogy type of thing for the muscular system. Oh wait never mind that wouldn't make much sense. Actually I can use that for the nervous system! Huh weird.

Structure and Function Relations

The structure and function of the muscular system, I believe, are very closely related. I think of this because for some parts of the digestive system, are aligned with involuntary muscles. These muscles help push food along the digestive system. See the structure of the muscle, being a smooth muscle, supports the function. I'm really sorry I couldn't think of anything better, but this is how the structure of the muscular system supports the function.
