Lesson Worksheet: Muscles and Movements Science

In this worksheet, we will learn practice stating examples of types and groups of muscles, measuring muscle strength, and describing how antagonistic pairs work together.

Q1:

Which statement about muscles is true?

  • AThe force exerted by your muscles is measured in kilograms.
  • BMuscles work in pairs by contracting at the same time.
  • CMuscles can push and pull and work together at a joint.
  • DAbdominal muscles can help with breathing during heavy exercise.
  • ELigaments attach muscles to bones to allow movement.

Q2:

What is the difference between a ligament and a tendon?

  • ATendons can contract but ligaments cannot.
  • BTendons attach muscle to bone but ligaments attach bone to bone.
  • CTendons are more flexible and elastic than ligaments.
  • DTendons are found at joints and ligaments are not.
  • ETendons work in antagonistic pairs but ligaments do not.

Q3:

Complete the sentence: When a muscle , it gets shorter and so pulls on the bone it is attached to. When a muscle , it returns to its orginal size.

  • Arests, tightens
  • Bcontracts, relaxes
  • Cconstricts, expands
  • Drelaxes, contracts

Q4:

What is the name of the muscle that makes up your heart?

  • ACardiac muscle
  • BTriceps muscle
  • CGut muscle
  • DBiceps muscle

Q5:

The figure shows antagonistic muscles bending and straightening the arm.

What is the name of structure X?

  • ATendon
  • BMuscle
  • CLigament
  • DBone

Which label (A, B, C, or D) is pointing to the triceps relaxing?

  • AB
  • BD
  • CA
  • DC

Q6:

The figure shows a student measuring his muscle strength by pushing down on a scale as hard as he can.

What muscle group is he measuring?

  • AGluteals
  • BShoulder
  • CTriceps
  • DAbdominals

Q7:

The figure shows an arm holding a weight of 25 N, positioned 0.25 m from the pivot at the elbow. The biceps muscle is attached to the bone by a tendon that is 0.05 m from the elbow pivot.

Calculate the force, in newtons, applied by the biceps muscle to hold the weight in position.
