Understanding Muscle Movement Mechanics

What is the primary function of the muscular system in relation to movement?

• To provide energy for the body

• To contract and pull on bones

• To produce hormones

• To protect internal organs

In a biceps curl, which muscle acts as the agonist?

• Triceps

• Quadriceps

• Biceps

• Hamstrings

During the action of kicking a football, which muscle acts as the antagonist?

• Quadriceps

• Hamstrings

• Biceps

• Triceps

What is the role of a fixator muscle?

• To contract and produce movement

• To relax and lengthen during movement

• To stabilise the origin of the agonist muscle

• To provide energy for muscle contraction

Which of the following is an example of an antagonistic pair of muscles?

• Biceps and triceps

• Quadriceps and deltoids

• Hamstrings and pectorals

• Gluteus maximus and latissimus dorsi

In sprinting, which muscles are primarily responsible for forward propulsion?

• Deltoids and pectorals

• Quadriceps and hamstrings

• Biceps and triceps

• Abdominals and obliques

What happens to the antagonist muscle during a movement?

• It contracts

• It relaxes and lengthens

• It stabilises the joint

• It provides energy

Which muscle group is the agonist when extending the knee?

• Hamstrings

• Quadriceps

• Biceps

• Triceps

What is the primary function of the agonist muscle?

• To stabilise the joint

• To contract and produce movement

• To relax and lengthen

• To provide energy

In the context of muscle movement, what does the term "antagonistic pair" refer to?

• Two muscles that work together to stabilise a joint

• Two muscles that work in opposition to control movement

• A single muscle that performs multiple functions

• A group of muscles that contract simultaneously
