How does a skeleton move?
Keywords:
  • Tendons: Muscles are connected to bones by Tendons (2)
  • Muscles: Muscles are needed to move bones attached by joints. They can contract or relax. (2)
  • Bicep: A muscle on top of the upper arm. (2)
  • Hamstrings: The muscles on back of the upper leg. (2)
  • Tricep: A muscle on underside of the upper arm. (2)
  • Quadriceps: The muscle on front of the upper leg. (2)
  • Joint: A joint is where two or more bones meet. (1)
  • Intercostal muscles: The muscles between the ribs (1)
  • Intercostal muscles: The muscles between the ribs. (1)
  • Ligaments: Joints are held together bone to bone by ligaments. (1)

T The muscle on top of the upper arm is called the Bicep. The muscle on underside of the upper arm is called the Tricep. The muscle on front of the upper leg is called the Quadriceps. The muscles on back of the upper leg are called the Hamstrings. The muscles between the ribs are called intercostal muscles. Give examples of antagonistic muscles in the arms and legs.

T Joints are held together (bone to bone) by Ligaments. Muscles are connected to bones by Tendons. How are the bones at a joint held together?

W Ligaments are elastic (stretchy) to allow movement. Tendons are not elastic to all muscles to exert a force on the bones. What is the difference between a ligament and a tendon?

T Muscles can only contract (pull) exerting a force and relax applying no force. Muscles can not What do muscles do to apply a force and is it a pulling or pushing force?

W To raise the lower arm, the Bicep must contract while the triceps relaxes and vice versa. When one muscle in an antagonistic pair is contracted, what will the other muscle do?

D Students to workout the movement of joints required to use a particular muscle. Students rate how easy it is to raise a 1kg mass. NB it is not safe to have student lift as heavy a weight as they can, even on appropriate gym machines. Students could measure the size of their muscles to see if their is a correlation.
