Physiology Quiz - Skeletal Muscle Physiology - Part 4
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) In skeletal muscle, the dihydropyridine (DHP) receptors are found in the:
(2) The diameter of a typical skeletal muscle cell could be as large as:
(3) In skeletal muscle cells, which of the following is a Ca2+ sensor?
(4) In skeletal muscle cells, which of the following is an ATPase?
(5) During muscle contraction, the H zone decreases in size.
