The attenuation reflex protects the cochlea from loud, low-frequency sounds by which of the following mechanisms?
A)Contraction of both stapedius and tensor tympani muscles
B)Contraction of stapedius muscle, relaxation of tensor tympani muscle
C)Relaxation of both stapedius and tensor tympani muscles
D)Relaxation of stapedius muscle, contraction of tensor tympani muscle

Question

Quizplus · Accepted Answer

The attenuation reflex involves the contraction of both the stapedius and tensor tympani muscles. This action helps to dampen the transmission of sound vibrations to the inner ear, protecting the cochlea from potential damage caused by loud, low-frequency sounds.
