4) Biceps brachii- Muscle originating from two points (Origin of the muscle is the criteria)

5) Levator scapulae- A muscle which lifts the scapula (Function of the muscle is the criteria)

6) Flexor carpi radialis- Muscle which bends joints closer ( A Flexion) (Function of the muscle is the criteria)

7) Piriformis- Pear shaped muscle in the gluteal region of the lower limb (Shape of muscle is its criteria)

8) Gluteu medius- Medium largest gluteal muscle (Size of the muscle is the criteria)
