acoustic meatus การใช้

Physical stimulation of the external acoustic meatus innervated by the auricular nerve elicits a cough, much like the other cough reflexes associated with the vagus nerve.
While the muscle modifies the auricular shape only minimally in the majority of individuals, this action could increase the opening of the external acoustic meatus in some.
While the muscle modifies the auricular shape only minimally in the majority of individuals, this action could increase the opening into the external acoustic meatus in some.
Other complications included otitis externa ( swimmer's ear ), which involves inflammation or bacterial infection of the external acoustic meatus, as well as pain, vertigo, tinnitus, and perforation of the ear drum.
Behind the internal acoustic meatus is a small slit almost hidden by a thin plate of bone, leading to a canal, the aqu鎑uctus vestibuli, which transmits the ductus endolymphaticus together with a small artery and vein.
