Muscle Flashcards
Objectives:
1. List the function of muscle tissue
2. Describe the function & organization of the connective tissue sheaths associated with skeletal muscles
3. Define the terms action, origin, & insertion in relation to muscle
4. Explain the role of prime moves, antagonists, synergists, & fixators in producing body movements
5. Define tendon, aponeurosis, & retinaculum
6. List criteria/strategies for naming muscles & give specific examples of each
7. Name the actions & attachments of specific muscles using guidelines from class
8. Name the muscles that form Rotator Cuff

| 1268849366 | Muscle Tissue Functions | Movement: Convert ATP to mechanical energy Stability: Maintain length on joints, maintain posture, antigravity Heat Production: 85% body heat Elasticity: Recoils when tension releases | 0 | |
| 1268849367 | muscle relaxation | Movement muscle produces, Act of removing tension from the muscles so as not to impede the freedom of movement. This process must be so developed through daily systematic exercises that it becomes automatic and unconscious. | 1 | |
| 1268849368 | Origin | Attachment site at stationary end | 2 | |
| 1268849369 | Insertion | Attachment site at mobile end | 3 | |
| 1268849370 | Antagonists | muscles that opposes primary mover | 4 | |
| 1268849371 | Tendon | Dense, regular connective tissue Connects Muscle to bone | 5 | |
| 1268849372 | sarcomere | Contractile unit of muscle | 6 | |
| 1268849373 | sliding filament theory | ...fibers dont shorten but slide past each other to contract | 7 | |
| 1268849374 | 3 types of muscles | cardiac smooth skeletal | 8 | |
| 1268849375 | muscle contraction | -Ca++ binds to troponin and causes it to change shape, which causes a change in shape of tropomyosin that results in a conformational change in the actin filament; thus, Ca++ clear the myosin binding sites on the actin and create cross-bridges to form | 9 |
