1 i.e skeletal

Answer 2

Too many to count. Think about it. You have all the muscles of the feet, lower leg (both front and back), hamstrings, quadriceps, arms, back, abs, neck, etc. It takes a cooperative effort of the entire body to walk correctly. In the legs alone the list would start like this: Vastus lateralus, Vastus Medialis, Vastus Intermedius, Rectus Femoris, Biceps Femoris, Semitendinosus, Semimembrinosus, Sartorius, etc. (that is just the major muscles of the upper leg, the big ones.) All of the muscles including the small ones would list in the hundreds.
