Stapedius muscle and tensor tympani
WebbElectromyographic recordings of the activity of the tensor veli palatini, tensor tympani, and stapedius muscles were obtained from several adult human subjects. Muscle … WebbContraction of the stapedius and tensor tympani muscles are integral parts of the acoustic reflex, defined as consensual, reflexive contraction of the muscles in response to stimuli (typically high-energy sound pressure) that leads to attenuated acoustic transmission. The tensor veli palatini muscle arises from a groove in the petrous portion ...
