What is abduction in joint movement?
Movement away from the midline of the body
Movement towards the midline of the body
Rotation around an axis of the body
Widening the angle at the ankle joint
Which pair correctly matches the muscle type with its control?
Voluntary muscles — you can control

Cardiac muscle — found in the stomach wall
Voluntary muscles — found only in the heart
Which description fits dorsiflexion at the ankle?

In an antagonistic pair, when one muscle contracts, the opposing muscle will do what?
Relax
Also contract
Shorten more forcefully
Rotate the joint
Which muscles form an antagonistic pair at the elbow?
Biceps and Triceps
Quadriceps and Hamstrings
Gastrocnemius and Tibialis Anterior
Pectorals and Deltoid
Which is true of an isometric muscle contraction?
Muscle contracts with no joint movement
Muscle shortens and movement occurs
Muscle lengthens due to a greater force
Joint rotates through a full circle
Which statement describes an isotonic contraction?
Muscle contracts and movement occurs
Muscle contracts but length does not change
Muscle relaxes while force increases
Joint angle widens without muscle action
Concentric contraction is defined as what action?
Muscle shortens generating force
Muscle lengthens under higher load
Muscle holds tension without motion
Joint rotates fully around axis
Eccentric contraction occurs when the muscle does what?
Lengthens due to greater opposing force
Shortens to generate joint movement
Maintains length while producing tension
Stops movement to stabilize a joint
