Physiology Quiz - Skeletal Muscle Physiology - Part 1
Skeletal muscle cells are characterized by their striated appearance when visualized under the light and electron microscopes. Collectively, skeletal muscle cells make up approximately 50% of the body’s wet (i.e., soft tissue) weight. Skeletal muscle cells perform highly important functions including generating force, motion, and even heat. Test your basic knowledge of skeletal muscle physiology by taking this simple quiz.
(1) The following ion(s) is/are involved in the skeletal muscle action potential:
(2) Under normal physiological conditions, the sarcoplasmic ATP concentration is about:
(3) This enzyme is responsible for the breakdown of acetylcholine at the neuromuscular junction:
(4) Ca2+ is involved in all of the following in human skeletal muscle cells EXCEPT:
(5) Which one of the following is NOT located in the striated muscle sarcomere unit?
