Sample short answers:
- Describe and define rigor mortis
- Describe and define the effects of exercise on a muscle
- Describe and define the atrophy of a muscle tissue
- Describe and sketch a motor unit
- Fully describe the sliding filament theory including cross bridge attachment, power stroke, detachment, and cocking of the myosin heads. Also include the role of calcium throughout this process.
- The layers of a connective tissue wrappings, including origin and insertion, and tendon and aponeurosises.
