VIII. MOVEMENT OF\u00a0SKELETAL\u00a0MUSCLE<\/strong><\/p>\n

A. Origin, insertion, belly<\/p>\n

B. Lever systems<\/p>\n

1. Class 1 lever<\/p>\n

Effort, Fulcrum, Resistance (=Load)<\/em><\/p>\n

2. Class 2 lever<\/p>\n

Fulcrum, Resistance, Effort<\/em><\/p>\n

3. Class 3 lever<\/p>\n

Fulcrum, Effort, Resistance<\/em><\/p>\n

C. Muscle Group Actions<\/p>\n

1. Agonist –the prime mover, causes a desired action<\/em><\/p>\n

2. Antagonist –opposite effect of the agonist<\/em><\/p>\n

3. Synergist –helps the agonist in the desired action<\/em><\/p>\n

4. Fixator –stabilizing muscle<\/em><\/p>\n

D. Naming of Skeletal Muscles<\/p>\n

1. Action –e.g. Extensor digitorum<\/em><\/p>\n

2. Origin and insertion –e.g. Sternocleidomastoid<\/em><\/p>\n

3. Direction of muscle fibers –e.g. External abdominal oblique<\/em><\/p>\n

4. Location –e.g. Tibialis anterior<\/em><\/p>\n
