  1. The main function of the muscular system is movement. Muscles are the only tissue in the body that has the ability to contract and therefore move the other parts of the body, but muscles often contract to hold the body still or in a particular position rather than to cause movement.[Points: 1]
  2. Another function of muscle tissue is the generation of body heat.[Points: 1]
  3. On the basis of the above, are the same muscles that are used to pick up a pencil also used to pick up a bowling ball.[Points: 1]
  4. Muscles continue contraction as long as they are stimulated by a ___________.[Points: 1]
  5. Tetanus is a state of complete and lasting contraction due to many nerve impulses sent in rapid succession.[Points: 1]
  6. There are isometric contractions and isotonic contractions. Holding an object still and maintaining posture is a result of ___________ contractions.[Points: 1]
  7. Muscle mass required to develop through weight lifting is the product of ____________ contractions.[Points: 1]
  8. The condition known as muscle fatigue, is when the muscles quickly tires and loses its ability to contract.[Points: 1]
  9. There are three types of muscle tissues: visceral, cardiac and skeletal. The ones considered to be ‘involuntary’ muscles are: (mark all that apply).[Points: 1]
  10. Of the three types of muscle tissues: visceral, cardiac and skeletal. The ones considered to be ‘smooth’ muscles are:[Points: 1]
  11. Those tough bands of dense regular connective tissue whose strong collagen fibers firmly attach muscles to bones are called:[Points: 1]
  12. Skeletal muscles can be named based on their location, origin and insertion, shape, size, direction and function, therefore a ‘deltoid muscle’ is being named based on which of the following:[Points: 1]
  13. … ‘gluteus maximus’[Points: 1]
  14. … ‘sternocleidomastoid’[Points: 1]
  15. The muscle that produces any particular movement of the body is known as an agonist or prime mover.[Points: 1]
  16. The agonist always pairs with an antagonist muscle that produces the opposite effect on the same bones.[Points: 1]
