The muscle which moves a body part towards the midline of the body is:
Correct answer: C. Adductor muscles
- A. Flexor muscles
- B. Extensor muscles
- C. Adductor muscles
- D. Abductor muscles
Explanation
The adductors as a group are responsible for bringing the legs inwards towards each other (adduction) when the leg is extended and stabilizing the pelvis in more controlled activities such as walking. A movement of a body part away from the midline, either of the body as a whole or that of the hand or foot, is termed 'abduction' and the muscles that are responsible for that movement are called 'abductor muscles'.

About Support and Movement
Support and movement covers the axial and appendicular skeleton, bone structure, joints and the arrangement of skeletal muscles. Muscle contraction is explained through actin, myosin, sliding filaments, calcium ions and ATP, while arthritis is distinguished as a disorder of joints rather than a normal part of movement.
