1Which statement about skeletal muscle cells in false?
- AThey can be up to 40cm in length.
- BThey are striated due to protein arrangement.
- CThey are cylindrical and aligned in parallel.
- DThey can have multiple nuclei.
2Myosin is the thin myofilament, and actin is the thick myofilament.
- AVerdadero

4Choose the statement that is false.
- ALonger muscle fibres means a smaller ROM.
- BMuscle fibres can shorten up to 50% in length when contracting.
- CPennate/oblique muscle fibres have a larger physiological cross sectional area but not a longer anatomical cross sectional area.
5Fibre Type I has [blank_start]high[blank_end] enzymatic/metabolic activity and is [blank_start]aerobic[blank_end]. It is slow twitching. Marathon runners may have more of this type.
Fibre Type II has [blank_start]low[blank_end] enzymatic/metabolic activity and is [blank_start]anaerobic[blank_end]. It is fast twitching. Usain bolt probably has a lot of this type.- Ahigh
- Baerobic
- Clow
- Danaerobic
6Fitting more fibres into the same space e.g. a pennate arrangement reduces the shortening ability of muscle but increases forces exerted by muscle.
