The Muscular System
Transcript of The Muscular System
What is the Muscular System?
The muscular system controls the movement of your body. Surrounding the skeletal system are 700 muscles that shield your bones and make up almost half of your weight! Each muscle makes up a discrete organ, made of skeletal muscle tissue, blood vessels, tendons, and nerves.
What Important Jobs does the Muscular System do?
There are more than 600 muscles in your body, all of which have different functions.
Some pump blood throughout your body to help lift any heavy objects, others allow you to work-out.
How Does this System Work With other Organs?
Although there are many systems that incorporate this one, the most obvious would be the circulatory system.
The circulatory system focuses on transporting nutrients into the muscle and diverts waste.
Both systems use the heart as the main organ.
The Three Muscle Types:
The three main types of muscle your body are: smooth muscle, cardiac muscle, and skeletal muscle.
How It Works
The bending and straightening aspects are two functions of your muscles.
Muscles work in opposing teams to create the full range of movement.
One set pulls to end the joint and the other pulls to straighten it.
The Digestive System Interactions:
For example, the muscles of your jaw enable you to chew food, while the muscles that line your esophagus transport the food from the mouth to the stomach.
The muscles that line the intestines move the digestive food along, and the muscles control sphincters that isolate the sections of the digestive system.
The skeletal system gives the skeletal muscle something to pull against so the muscle can move.
The muscle gives the body support.
Here we have some diagrams of the muscular system.
On the left is an example of a male muscular system. <-
On the right is one of a woman.->
Here we have some examples of the muscular system in motion.
Sports are a great way to see your muscles in action!
For example, in the picture above, we have a tennis player, observe how different the muscles contract and tighten based on the action she is doing.
How Does it Accomplish These Actions?
Blood is pumped throughout the muscle tissue, to help your body to function.
Your muscular system, without you knowing it works throughout the day, at all times.
Here is an example of where the two systems of the human body meet.
This is a diagram of where the digestive and muscular systems interact, and how many organs play a crucial role in the jobs of both systems.
The Skeletal System Interactions:
Smooth muscles are also known as involuntary muscles and are usually made in sheets, or layers, with one layer of muscles separating the two.
You cant control the smooth muscles.
In the digestive system, your stomach muscles contract and relax based on the passing of food.
this is what smooth muscle looks like.
The muscles in the heart release and contract making the heart pump blood in and out into your body.
This is one of the most important muscles in your body because it allows oxygen to pass through the blood and into your brain.
Like the smooth muscle, this is not one that you can control. It does it job on its own, with no direction.
Here we have two examples of what a heart looks like.
The Skeletal Muscle:
The skeletal muscles are voluntary muscles.
Your skeletal muscles works along with your bones to give your body the power and strength it needs to accomplish its various actions.
In many cases, the skeletal muscle is attached to one end of a bone.
The muscle outlines the bones, and serves as a protector for your skeleton.
The muscles are binded by tendons, which are cords made of tough tissue, and work by connecting the pieces of bone and muscle.
This is what a skeletal muscle looks like.
The Major Muscles:
Rectus Abdominus Muscle:
Gluteus Maximus Muscle:
The Deltoid Muscle:
Your deltoid muscles are located in your shoulders.
These muscles help your shoulders move, from swinging a softball bat to shrugging.
These muscles give your shoulders the strength and capacity that they they need.
The Pectoral Muscles:
They are located on each side of your upper chest.
They are most commonly seen in boys.
They generally appear when boys hit puberty, they become larger.
Your abs are located below your pectorals under your ribcage.
Here are a couple of examples of what abdominal muscles look like.
If you tense your arm, you can see or feel your biceps contract.
They are located on the upper part of your arm.
Here are two comparing diagrams
Your quadriceps are located in front of your thighs.
The people who have strong quads are those who run, bike, or play sports.
Your quads make it easier to run longer distances, or climb up stairs.
Gluteus Maximus Muscle:
It is also known as your butt muscle. It is the muscle that is under the skin and fat of your butt.

Muscular Cancer is an unhealthy tumor growth in the skeletal muscles, it most commonly involve a benign tumor.
The tumor is created from the increased or altered growth of the muscle cells.
Malignant tumors can spread into surrounding muscle cells and eventually kill you, while benign tumors cannot grow, and must remain in the designated tissue.
The symptoms include noticing a lump under the skin, and either a slow or rapid growth.
The most common treatment will be either surgery, chemotherapy, or radiation.

Muscular Dystrophy is inherited genetically and are formed as a result from mutations in the proteins that make up your muscles. In simpler words, muscular dystrophy is the death of muscle cells.
The symptoms include weakening muscles, and problems breathing.
There is no treatment for this muscular disease. It is highly encouraged to seek medical help early, to have an early prevention analysis.
This is an example of how muscle dystrophy affects your physical appearance.
