How do muscles and bones work together to produce movement GCSE PE?

Muscles move body parts by contracting and then relaxing. Muscles can pull bones, but they can’t push them back to the original position. So they work in pairs of flexors and extensors. The flexor contracts to bend a limb at a joint.

How do muscle and bones work together to produce movement?

The muscles of the muscular system keep bones in place; they assist with movement by contracting and pulling on the bones. To allow motion, different bones are connected by joints which are connected to other bones and muscle fibers via connective tissues such as tendons and ligaments.

How do muscles and bones work together to allow movement quizlet?

Your bones and muscles work together through a series of impulses and signals communicated between the brain and skeletal muscles. In order to move, the nervous system then sends signals a skeletal muscle to contract. When the muscle contracts, this movement causes the attached bone to follow.

How do muscles cause movement GCSE PE?

Muscles cause movement by contracting across joints. Muscles are attached to the skeleton by tendons in two places: the insertion.

How do bones and skeletal muscles work together?

Skeletal muscles are attached to the skeleton by tough connective tissues called tendons(see Figure above). Many skeletal muscles are attached to the ends of bones that meet at a joint. The muscles span the joint and connect the bones. When the muscles contract, they pull on the bones, causing them to move.

How do the muscles and bones work together to flex the knee?

When you straighten your leg, the quadricep muscles pull on the quadricep tendon, this pulls the kneecap to make the knee extend. When you bend it, the hamstring muscles contract and pull the tibia backwards, causing the knee to flex.

What is it called when two muscles work together to create movement?


This is called antagonistic muscle action. The working muscle is called the prime mover or agonist. (it’s in agony!) The relaxing muscle is the antagonist. The other main pair of muscle that work together are the quadriceps and hamstrings.

How do muscles allow movement quizlet?

Muscles relax and contract when one muscle pulls and moves your body part and if you want to do the opposite movement the opposite muscle contracts, allowing the first muscle to relax. Muscles are attached to bones and receive chemical signals from the brain that tell the muscle to move the bone it is attached to.

How are bones connected to muscles quizlet?

Bones are attached to muscles by tendons. Ligaments connect the bones to each other at the joints and cartilage protects the bones and allows them to glide over each other during movement.

Why are the bones and muscles combined into one body system?

Your musculoskeletal system includes bones, muscles, tendons, ligaments and soft tissues. They work together to support your body’s weight and help you move. Injuries, disease and aging can cause pain, stiffness and other problems with movement and function.

Why are bones and muscles important for movement and physical activities?

Your bones and muscles work together to support every movement you make on a daily basis. When you are physically active you strengthen your muscles. Your bones adapt by building more cells and as a result both become stronger. Strong bones and muscles protect against injury and improves balance and coordination.

What is the function of the muscular system GCSE PE?

The muscular system works in conjunction with the skeleton to produce movement of the limbs and body. Ligaments and tendons are two main types of connective tissues that help the muscular-skeletal system produce movements.

How does bone shape and type aid movement?

The bones of embryos are made largely of cartilage. They are soft.

Bone growth.

Type of bone Example Function in sport
Flat (Plate) Ribs, cranium Protection of vital organs, attachment of muscles to help movement
Irregular Vertebrae, face Provide shape, protection

How do the muscles attached to bones bring about movement class 6?

Muscles are attached to the bones of our skeleton through strong fibres called tendon. When the muscles attached to bone contracts, it pulls the bone due to which the bone moves at the joint.
