Which of the following are functions of the skeletal system

• Protection of internal organs

• Blood cell production

• A site of attachment for muscles

• All of the above

Reciprocal inhibition is when

• muscles work in pairs where both contract and shorten to produce movement

• a muscle contracts and applies force against a resistance with no significant movement occurring

• muscles work in pairs where both muscles relax and lengthen to produce a movement

• one muscle or group of muscles contracts while its opposite relaxes

The anatomical term, medial, means

• towards the back of the body

• towards the midline of the body

• away from the midline of the body

• closer to the foot

• Skull, sternum, humerus, pelvis, femur

• a) Shoulder girdle, arms, pelvic girdle, legs

Hinge joints permit the following movements:

• flexion, extension, rotation

• flexion, extension, circumduction

• flexion, extension

• flexion, extension, plantar flexion, dorsiflexion

What is the difference between ligaments and tendons?

• Ligaments connect muscles to bone and tendons connect bone to bone

• Tendons connect muscle to bone and ligaments connect bone to bone

• Ligaments are made of cartilage and tendons are made of connective tissue

When using anatomical terms, which of the following is correct?

• The hamstrings are superior to the quadriceps.

• The knee joint is inferior to the hip joint.

• The elbow is lateral to the wrist.

Isometric contractions occur when:

• a muscle contracts and decreases the angle at a joint

• the muscle lengthens and shortens

• muscle tension is produced, but no joint movement or action takes place.

• a muscle contracts and increases the angle at a joint

The three classifications of joints are

• hard, soft, squishy

• hinge, ball and socket, pivot

• Fibrous, cartilaginous, synovial

• Fibre, carbohydrates, proteins

Synovial joints are:

• immovable

• slightly movable

• freely movable
