© HEB MUSCLES AND MOVEMENT KS3 Biology By Dr H E Bloomfield
© HEB How our Muscles Work Muscles work by C ING (getting shorter and fatter) and pulling on bones.
© HEB But once contracted, a muscle cannot again by itself. So each muscle needs a partner to pull it longer again and move the bone back in the opposite direction. How our Muscles Work
© HEB How our Muscles Work
© HEB Two muscles working together in opposite directions are called A muscles. How our Muscles Work
© HEB The BICEPS and TRICEPS in our arm are ANTAGONISTIC muscles. They work as a pair and in opposite directions. How our Muscles Work
© HEB How our Muscles Work
© HEB Bending our Arm BICEPS contracts and bends arm TRICEPS relaxes and is pulled longer
© HEB Straightening our Arm BICEPS relaxes and is pulled longer TRICEPS contracts and straightens arm
© HEB How our Muscles Work Muscles are attached to bones by strong non- stretchy TENDONS. muscle tendons
© HEB Our Achilles tendon in our heel
© HEB How Arm Muscles Work Hinge joint
© HEB Muscles, bones and joints
© HEB TAKING THE STRAIN How Strong are your Muscles?
© HEB 1.Put the scales on the bench. Push down with your fists as hard as you can. My result is __________ N
© HEB 2.Put the scales under the edge of the bench. Push upwards with your hands as hard as you can. My result is __________ N
© HEB 3.Try squeezing the scales with your fingers. My result is __________ N
© HEB 4.Hold the scales between your two palms. Push them together as hard as you can. My result is __________ N
© HEB WHERE DO MUSCLES GET THEIR ENERGY FROM?
© HEB Muscles get energy for contraction from R ENERGY
© HEB Energy for Muscle Contraction ENERGY Glucose + Oxygen
© HEB Energy for Muscle Contraction + CO 2 + Water ENERGY Glucose + Oxygen As the process uses oxygen, it is sometimes called aerobic respiration.
© HEB THE END
How do Bones and Muscles Work Together?. Bones and Muscles Your bones and muscles have to work together in order for you to move. Most of the body’s bones.
How Do Muscles Work? Types of Movement. Flexion: The decreasing of an angle between bones. One of the bones of the joint moves towards the other bone.
Voluntary Muscles (skeletal) Names of Muscles Deltoid Biceps Abdominals Quadriceps Pectoral Latissimus Dorsi Trapezius Triceps Gluteals Hamstrings Gastrocnemius.
MUSCLES. The muscles in the body each fall into one of three groups: 1.VOLUNTARY or SKELETAL MUSCLES- these muscles are under the control of our.
Each motion had a limited range of movement. The types and ranges of movement differed. Different joints allow rotational movements, angular movements,
