Deltoid Supinator Rectus femoris Teres minor Triceps brachii a. number of divisions b. size c. shape d. action e. location Multiple choice: 6. __________ muscles are more designed to produce a wider range of movement. a. Pennate b. Radiate c. Parallel d. Unipennate 7. _______________ muscles are designed to produce more power. a. Pennate b. Radiate c. Parallel d. Bipennate 8. The rectus abdominus is an example of a __________ muscle . a. Fusiform b. Strap c. Sphincter d. Flat 9. The Sartorius is an example of a ____________________ muscle . a. Fusiform b. Strap c. Sphincter d. Flat 10. The rectus femoris is an example of a _______________ muscle. a. Unipennate b. Bipennate c. Radiate d. Multipennate 11. The muscles’ ability to be sensitive to electrical, chemical or mechanical stimuli is called : a. Contractility b. Irritability c. Elasticity d. Extensibility 12. The ability of a muscle to contract and develop tension against resistance when stimulated is called: a. Contractility b. Irritability c. Elasticity d. Extensibility 13. The ability of a muscle to be stretched back to its original length following contraction is called: a. Contractility b. Irritability c. Elasticity d. Extensibility 14. The ability of a muscle to return to its original length following stretching is called: a. Contractility b. Irritability c. Elasticity d. Extensibility 15. The muscle’s __________ is a specific movement of the joint resulting from a concentric contraction of a muscle which crosses the joint. a. Action b. Innervation c. Origin d. Insertion 16. The muscle’s _____________ or proximal attachment is generally considered the least moveable part . a. Action b. Innervation c. Gaster d. Origin 17. The muscle’s __________ or distal attachment is generally considered the most moveable part. a. Action b. Origin c. Gaster d. Insertion 18. When a muscle lengthens, it is undergoing a _____________ muscle action. a. Concentric b. Isometric c. Eccentric 19. When no movement is occurring, but tension is being developed within the muscle, it is called: a. Eccentric b. Concentric c. Isometric d. Isotonic 20. A ________________ contraction results in muscle shortening. a. Concentric b. Eccentric c. Isometric d. Isotonic 21. The highest level of control occurs at the : a. Cerebellum b. Cerebral cortex c. Brain stem d. Spinal cord 22. The ________________ is a major integrator of sensory impluses and providing feedback. a. Cerebellum b. Basal ganglia c. Cerebral cortex d. Spinal cord 23. Sensory nerves are also called _____________ nerves a. Afferent b. Efferent 24. Motor nerves are also called _____________ nerves a. Afferent b. Efferent 25. ______________ are areas of the skin supplied by a specific spinal nerve. a. Dermatome b. Myotome c. Dendrites d. Neurons 26. ________________ are specific muscles or groups of muscles supplied by a specific spinal nerve. a. Dermatome b. Myotome c. Dendrites d. Axons 27. Regardless of the number of motor units involved, the individual muscle fibers within a given motor unit will fire and contract either maximally or not at all. This concept is called : a. The muscle force velocity relationship b. All or none principle c. Muscle length tension relationship 28. When contracting against a light resistance the, the muscle is able to contract at a high velocity. This is an example of the : a. All or none principle b. Muscle length tension relationship c. Muscle force velocity relationship 29. The maximal ability of a muscle to develop tension and exert force varies depending upon the length of the muscle during contraction. The greatest amount of force can be developed when the muscle is stretched between 100 – 130% of its resting length. a. All or none principle b. Muscle length tension relationship c. Muscle force velocity relationship 30. Draw the graph of the muscle force velocity relationship in the space provided below. Make sure to include and label the following: force, isometric, eccentric, concentric, lengthening velocity, shortening velocity.
