  We walk by using our muscles. They lift our bones and make us walk. What happens at a higher level is brain sends a message to your muscles which take the message and lift your leg. The levers involved in walking are your knee and your ankle.
  The muscles that are involved in walking are your: Gluteus Maximus this muscle keeps you upright. Your Quadriceps help you straiten your knee. Your Gastrocnemius helps you stand on your toes.
  When you bend your knee your quadriceps contract and your Gastrocnemius relaxes. When you stand on your toes your Gastrocnemius contracts and your Quadriceps relax.

  Though it may not seem like it, a lot of things are happening in a person's body when they walk. The joints involved are the knee and ankle joint. When you walk you are bending and straitening your knee. You are also lifting your ankle and you go through your foot. Some of the major muscles involved are your gluteus maximus, gastrocnemius, quadriceps, satorius, and your hamstrings. The gluteus maximus extends your thigh and the quadriceps help straighten your leg. Your gastrocnemius helps you stand on your toes while the satorius flexes the knee and hip. Last but not least, your hamstring muscles bend your leg at the knee. Now you may be wondering, how do all of these muscles and joints work together to help us walk? When you straighten your leg your quad muscles (which are located in the front of your body) contracts at your knee. When your quads are contracting your ham strings are releasing. Also the tibialis anterior (located in the front of your body and flexes your foot) is contracting when you flex your foot. All of that adds up to what basically happens when you walk.

  The muscles that are involved in walking are your: Gluteus Maximus this muscle keeps you upright and is found in the buttocs. Your Quadriceps help you straiten your knee. Your Gastrocnemius helps you stand on your toes.
  When you bend your knee your Quadriceps contract and your Gastrocnemius relaxes. When you stand on your toes your Gastrocnemius contracts and your Quadriceps relax. This is the system that makes you walk.

  We use muscles to walk. The muscles that are used are the Quadriceps, the Gluteus Maximus, and the Gastrocnemius. The Gluteus Maximus helps you stand straight, while the Gastrocnemius helps you stand on your toes. The Quadriceps help you also by straightening your knees. When you start to walk, your knees contract and your Gastrocnemius relaxes, helping and letting you walk. Standing on your toes also helps you. When you stand on them, your Gastrocnemius contracts and your Quadriceps relax, and that's how you walk.

  We walk by our muscles and bones working together. The skeletal and muscular systems work together by using tendons to connect muscles to bone. Your muscles work in pairs one contracts and one expands. This allows us to move our bones in many directions. There are three major joints that allow you to walk. The hip which is a ball and socket joint, the knee which is a hinge joint and the ankle which is a gliding joint. Your femur is covered with muscles these muscles are called quadriceps and on the back your hamstrings. The quadriceps contract and your hamstrings relax as you pull your knee up. The tibia and the fibula are also covered by muscles called gastrocnemius. They help you point your toes as you walk. All of these muscles cover joints to to pull the bone up and down. All of the bones in your legs move when you walk. Your Gluteus maxims make you stay upright while you walk. That is how your body walks.

  The levers involved are the Ball and Socket Joints in your hips, the Hinge Joint in your knees, and the joints in the ankles. The most important muscles that are involved are, the Quadriceps, the Hamstrings, your Shin Muscle, and your Gluteus Maximus. When the Quadriceps contract it pulls the leg up, and the hamstrings lengthen. Then when the foot comes up to touch the ground on the heel, the shin muscle then pulls the ankle up. When you go to push off the ground with your foot, your hamstring contracts and pulls your leg up. The Quadriceps contract and the hamstring lengthens. The shin muscle pulls the ankle up, and the foot hits the ground. When you push off, you hamstring LENGTHENS and then pulls your leg up, along with the quadricep.

  How we walk is pretty simple, our hip joint which is called the ball-and-socket joint rotates which make the hamstrings in the back of your upper leg to lengthen. Then, the hinge joint in your knee lifts and straightens and cause some quadriceps to contract which make the smaller muscles in your ankle to straighten out then push forward. After that part, the tendons in your toes to push out and then all of the steps are reversed, the quadriceps in your knee lengthen and the hamstrings contract, and the hamstrings in your hip lengthen and your quadriceps contract. Then all of these steps repeat to create walking.

  Your quadriceps muscle helps you straighten your knee when you walk, and your gastrocnemius muscle helps you stand on your toes. Your gluteus maximus muscle straightens your hip joint and holds you upright. Your hinge joint in your knee bends and contrast. Well you ankle muscle tightens.

  Thanks Kids! You never know when the extra credit will come in handy, huh? O'B
