Muscles and Muscle Groups

Identify the muscles that make up the quadriceps femoris group

• Vastus lateralis, vastus medialis, vastus intermedius, rectus femoris

• Biceps femoris, semitendinosus, semimembranosus, rectus femoris

• Pectoralis major, pectoralis minor, serratus anterior, rectus femoris

• Deltoid, trapezius, latissimus dorsi, rectus femoris

Which of the following exercises would best strengthen the pectoral muscles: Lunges, Bicep curls, Crunches, Chest press?

• Lunges

• Bicep curls

• Crunches

• Chest press

As the athlete lowers the weights, his biceps undergo-

• isotonic concentric contraction

• isometric contraction

• isotonic eccentric contraction

• static contraction

When a muscle undergoes atrophy in response to disuse,

• It increases in size and strength.

• It remains unchanged in size.

• It becomes more flexible and elastic.

• All of the above

What is the primary function of the deltoid muscles?

• Raising the arm

• Flexing the elbow

• Rotating the wrist

• Extending the shoulder

This muscle group bends the torso in a forward direction (think crunches), balance

• abdominals

• quadriceps

• hamstrings

• pectorals

The type of muscle contraction where the muscle tenses but does not shorten.

• Isotonic

• Isometric

• Eccentric

• Concentric

This is showing the major muscle group on your back, called what?

• latissimus dorsi

• trapezius

• rhomboid

• erector spinae

The increase in muscle size.

• Atrophy

• Hypertrophy

• Dystrophy

• Sarcopenia

What is the opposing muscle group for the biceps?

• Triceps

• Quadriceps

• Hamstrings

• Pectorals
