The Muscle System makes up nearly half of the human body weight. Some of your muscles are considered involunatry and some are voulantary. If your muscles are controlled then they are voluntary. If they are not controlled then they are invoulantary. Your skeletal muscles are voulantary and your cardiac and smooth muscles are invoulantary.
How Does The Muscular System Work?
You may ask that question, but nobody knows the answer. Well here it is, the muscular system puts pressure on the bones that causes them to contract and move the joints which aids in walking, raising hands, running and talking.Your muscular system aids in movement by contracting and flexing of tissues which are attached to the bone by tendons and ligaments.
Examples of involuntary:
An example for involuntary is when your heart continues to pump blood from your heart into your body.
Examples of voulantary:
Like when you move your toes around.
There are three types of muscular systems: skeletal , cardiac, and the smooth muscle. The skeletal muscle are attached to the skeleton. The cardiac muscle is located ibn the heart.
The Skeletal System is what your body is all the bones in the body and you tissues. Your teeth is also apart of your skeletal system.
How does the Skeletal Systemhelp us?
The main job of the skeletonis to provide support for our body. Without your skeleton, your body would probably just claspe into a pile of heap.Your skeleton also keeps the internal organsand fragile body tissues. The brain, eyes, heart, lungs and spinal cord are all protected by your skeleton. Bones provide the structure for muscles to attach so that our bodies are able to move.
The body of a baby has more bones than an adult does. A baby has about 270 bones and an adult has 206 bones. The reason babies have more bones than adults is because as a baby you have small bones that are not really connective. Like your knee bone, if you are a baby it is in 10 different pieces and as an adult that bone is in one piece.
What is a bone made up of?
A typical bone has an outer layer of hard or compact bone, which is very strong, dense and tough. Inside this is a layer of spongy bone, which is like honeycomb, lighter and slightly flexible. In the middle of some bones is jelly-like bone marrow, where new cells are constantly being produced for the blood. Bones are tough and usually don't break even when we have some pretty bad falls.
How do you keep your bones healthy?
Bones need regular exercise to stay as strong as possible. Walking, jogging, running and other physical activities are important in keeping your bones strong and healthy. Riding your bike, basketball, soccer, gymnastics, baseball, dancing, skateboarding and other activities are all good for your bones.
