In large groups of muscles, such as the quadriceps, anatomical regions may be designated as surface (closer to the skin), intermediate or deep (closer to the bone). The different regions may have different ratios of slow-oxidative to fast glycolytic fibers. Data for citrate synthase activity and tetanus frequency for different regions of the quadriceps are shown below. Which region probably has the highest proportion of fast glycolytic muscle fibers? Surface Intermediate Deep Muscle Muscle Muscle Citrate synthase activity 12 15 18 Tetanus frequency (Hz) 70 60 40 Surface Intermediate Deep

There are seven types of muscle fibbers based on their twitching ability, and they are:
- I (Slow oxidative)
- IC
- IIC
- IIA (fast oxidative glycolytic)
- IIAC
- IIAB
