Acoustic reflex contraction of the stapedius muscle stiffens the middle-ear, thus decreasing middle-ear admittance; this can be measured thanks to tympanometry. The acoustic stapedius reflex can also be recorded by means of extratympanic manometry (ETM). As the stapedius muscle is innervated by the facial nerve, a measurement of the reflex can be used to locate the injury on the nerve. If the injury is distal to the stapedius muscle, the reflex is still functional. A measurement of the reflex can also be used to suggest a retrocochlear lesion (e.g., vestibular schwannoma, acoustic neuroma). The acoustic reflex normally occurs only at relatively high
History of beliefs about the human body about what he proposed as the discovery of the clitoris, stated that, "like a penis, "if you touch it, you will find it rendered a little harder and oblong to such a degree that it shows itself as a sort of male member." (There was much debate on the actual discovery of the clitoris between male European scientists and many claimed to have described it first: by dissecting the human body and writing down what was observed these European scientists could claim in their idea of the body that they had discovered or created new knowledge.) This one-sex model was
