What would happen if you did not have the stapedius and tensor tympani muscles? A. The ear canal would stay permanently closed.
almond37 [142]
<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

kaheart [24]

Answer;

A) island forms and mainland forms descended from common ancestors.

Explanation;

-Islands tend to host very distinct but limited sets or species; on a given island a spectacular collection of one related group of species would be present and thriving, but many entire families or even higher taxa would be completely absent.

-All the species on the islands and the nearest continent are closely related to one another, however, each species had a set of adaptations that suits it for a particular environment. This means that the island forms and mainland forms descended from common ancestors.
