5 a day GCSE PE 9-1revision questions- Muscles Vol11

The video tutorial covers the muscular system, focusing on muscle attachment, types of contractions, muscle growth, and movement at joints. It explains how muscles attach to bones, the difference between isometric and isotonic contractions, the concept of muscles working in antagonistic pairs, and specific muscle movements like dorsiflexion at the ankle.

How do muscles attach to bones?

• Via cartilage

• Via tendons

• Via ligaments

• Via synovial fluid

Which type of muscle contraction involves no change in muscle length?

• Isometric contraction

• Isotonic contraction

• Concentric contraction

• Eccentric contraction

What is the term for muscles increasing in size and strength?

• Dystrophy

• Atrophy

• Hypertrophy

• Myopathy

In muscle movement, what is the role of the agonist?

• To relax during movement

• To initiate the movement

• To oppose the movement

• To stabilize the joint

Which muscle action is responsible for dorsiflexion at the ankle?

• Eversion

• Inversion

• Dorsiflexion

• Plantar flexion
