stapedius造句

• The stapedius stiffens the ossicular chain by pulling the stapes ( stirrup ) of the middle ear away from the oval window of the cochlea and the tensor tympani muscle stiffens the ossicular chain by loading the tympanic membrane when it pulls the malleus ( hammer ) in toward the middle ear.
• This is a problem which may be caused by genetic differences, stress or ill-health, or by abnormal responses in the tensor tympani ( tonic tensor tympani syndrome ) and stapedius muscles, which function in the normal acoustic reflex response that protects the inner ear from loud sounds.
• The "'acoustic reflex "'( also known as the stapedius reflex, middle-ear-muscles ( MEM ) reflex, attenuation reflex, or auditory reflex ) is an involuntary muscle contraction that occurs in the middle ear in response to high-intensity sound stimuli or when the person starts to vocalize.
