The cone of light, or light reflex, is a visible phenomenon which occurs upon examination of the tympanic membrane with an otoscope. [1] Shining light on the tympanic membrane causes a cone-shaped reflection of light to appear in the anterior inferior quadrant.
In the anatomy of humans and various other tetrapods, the eardrum, also called the tympanic membrane or myringa, is a thin, cone-shaped membrane that separates the external ear from the middle ear. Its function is to transmit changes in pressure of sound from the air to the ossicles inside the middle ear, and thence to the oval window in the ...
The most common otoscopes consist of a handle and a head. The head contains a light source and a magnifying lens, typically around 8 diopters (3× magnification), [citation needed] to help illuminate and enlarge ear structures. [3] The distal (front) end of the otoscope has an attachment for disposable plastic ear specula.

The tympanic duct or scala tympani is one of the perilymph-filled cavities in the inner ear of humans. It is separated from the cochlear duct by the basilar membrane , and it extends from the round window to the helicotrema , where it continues as vestibular duct .
Flashes of light. Temporary vision loss "For some people, it goes beyond the visual cortex," Broner says. "They have stroke-like symptoms where the words aren't coming out right or it sounds ...
Accused murderer Luigi Mangione’s grandmother reportedly left tens of millions of dollars to her children and grandchildren after she died, but did so on one condition: that any grandchild ...
Auditory ossicles from a deep dissection of the tympanic cavity. Sound waves travel through the ear canal and hit the tympanic membrane, or eardrum. This wave information travels across the air-filled middle ear cavity via a series of delicate bones: the malleus (hammer), incus (anvil) and stapes (stirrup).
