Muscle physiology

 

6 Questions

 

  1. Briefly describe the effect of resting muscle length and load conditions on the tension generated by a skeletal muscle. How do these factors affect the velocity of shortening? (01A2)
  2. Briefly discuss the relationship between structure and function in skeletal muscle. (00B5)
  3. Briefly describe the difference between a single twitch and a tetanic contraction in a skeletal muscle fibre. Include in your answer the physiological basis for the development of a tetanic contraction. (00A4)
  4. Briefly describe the structure of a mammalian skeletal muscle fibre and explain how its structure is related to its contractile function. DO NOT describe excitation-contraction coupling. (98A3)
  5. Briefly discuss the role of calcium in the coupling of electrical and mechanical events in skeletal muscle. (1993)
  6. Write short notes on isometric and isotonic muscle contraction. (1990)
