<h2>(D) is the correct option </h2>

Explanation:

  • Both the stapedius and tensor tympani are striated muscles
  • The stapedius is about 6 mm in length, arises from the pyramidal process and the tendon attaches to the posterior neck of the stapes
  • The stapedius is a muscle with a high oxidative capacity
  • The tensor tympani is about 25 mm in length, the muscle is not as strong as the stapedius, and the tendon also contains more elastic tissue and fat
  • The tensor tympani courses through a bony canal in the wall of the anterior middle ear, and attaches to the neck of the manubrium
  • The tensor tympani and stapedius muscles are protective reflexes
  • They reduce the amount of sound that gets into the inner ear
  • They are somewhat similar to the blink reflex thus they can be triggered by loud noise, and when they go off, both ears can be involved
  • If stapedius and tensor tympani muscles is not present then loud sounds would cause the ossicles to move too much, potentially causing damage to the inner ear

  • The national normal or per capita Ecological Footprint of utilization is equivalent to a <em>nation's Ecological Footprint of utilization isolated by its populace.  </em>

  1. <em>Increase your kilowatt hours by 1.85. For instance, 67 hrs X 1.85 = 123.95 lbs of CO2.  </em>
  2. <em>Increase your flammable gas use (therms) by 13.466. For instance, 19 therms X 13.466 = 255.854 lbs of CO2.  </em>
  3. <em>Increase gallons or propane utilized by 13.  </em>
  4. <em>Increase gallons of fuel utilized by 22.</em>
