Module 4 Microscopic Muscle Anatomy
Slide Show #1 Microscopic Muscle Anatomy
This slide show covers:
- Functions of muscles
- 3 types of muscle tissue (skeletal, cardiac, smooth)
- Characteristics of all muscles
- Skeletal muscle fiber structures
- Structure of a skeletal muscle
- Connective tissue wrappings of a skeletal muscle
- The sarcomere
- Actin & myosin
- Attachments of skeletal muscle
Slide Show #2 Muscle Contraction & Sliding Filament Theory
This slide show covers:
- Skeletal muscle contraction
- Neuromuscular junction
- Action potentials
- Excitation-contraction coupling
- Steps of muscular contraction
- Sliding Filament Model
- Cross-bridge cycling
- Muscle relaxation
- Energy sources for contraction
- Oxygen debt
- Muscular response to stimulus
- Threshold stimulus
- All or none response
- Muscle fatigue
- Twitch, summation, tetanus
- Isotonic & isometric contractions
Slide Show #3 Skeletal Muscle Actions
This slide show covers:
- Muscles as levers
- Origin & insertion
- How skeletal muscles interact (agonist, prime mover, synergist, antagonist)
- Ways muscles are named
- Muscle Actions (common surface muscles of the head & shoulders, trunk, arm, and leg and their actions)
