Muscles in the Leg
Hi!! My name is Bob and today we will be learning about Muscles in the leg.
First thing! A leg only has a skeletal muscle. And that means that all the muscle in the leg are voluntary. Which means that it moves when it wants to.
The muscles in your leg are attached to the bones of your skeleton and provide the force that is needed to move your bones. So, the muscle shortens and pulls on the bones that are attached.
Muscle attached to the bone.
All the muscle in the leg have it's funcions and here we are going to talk about the upper parts and the lower parts of the muscles in the leg.
So I've been doing some research online and I found a page that will help you learn the purpose of the upper and lower part of muscles in the leg. Here let me show you!

The lower part of the muscle in the leg also has a porpuse,the muscles that are attached to your bone move your feet all the way down to your toes and when the upper part of your leg wants to bend,it sopports alot of it's weight to the lower part and it helps maintain balance.
The muscles in the upper part of the leg basicly gives directions to the muscles in the lower part of the leg and it makes your knee bend thought it gives most of the weight to the
Well that's that ! Know let me show you how our leg muscles help us do some of the sports we like.
In sprinting you obviously use your legs and at the the starting point you flex your leg and when you start you push the lower part of your leg as hard as you can and you start running. So here you use the lower part of your leg.
In skiing when you want to turn right you put more weight on your right side and when you want to go left you put more weight on the left side. And here you use the upper part of your leg.
Now remember... the leg muscles can be broken into two groups, the upper leg muscles and the lower leg muscles. The upper and lower leg can be furthere divided into anterior(front) and posterior(back) of leg muscles. The primary front leg leg muscles , also called the thigh muscles,are the four muscles of the quadriceps femoris. These are the vastus intermedius,vastus mediallis,vastus lateralis, and rectus femoris.These muscles are responsible for extending or straightening the leg. The muscles at the back of the leg are often called hamstrings. These muscles inclued the biceps,femoris, semitendinosus and semimembranosus.These muscles are responsible for flexing or bending the leg at the knee.
Well I think that wraps it up! Hopefully you learned all you needed to know about leg muscles! Bye!! :)
