The tensor tympani is meant to pull the tympanic membrane inward, increasing tension of the tympanic membrane. It's like a calming mechanism that's in place in order to stabilize volume and respond to noise fluctuations, that also provides inner ear protection from loud sounds. It also helps ventilate the inner ear through the Eustachian Tube.
In many people with hyperacusis, an increased activity develops in the tensor tympani muscle in the middle ear as part of the startle response to some sounds. This lowered reflex threshold for tensor tympani contraction is activated by the perception/anticipation of loud sound, and is called tonic tensor tympani syndrome (TTTS). In some people ...
The acoustic reflex (also known as the stapedius reflex, [1] stapedial reflex, [2] auditory reflex, [3] middle-ear-muscle reflex (MEM reflex, MEMR), [4] attenuation reflex, [5] cochleostapedial reflex [6] or intra-aural reflex [6]) is an involuntary muscle contraction that occurs in the middle ear in response to loud sound stimuli or when the person starts to vocalize.
Watch doctors discover the tiny arachnid — if you dare.
Facing the inner ear, the medial wall (or labyrinthic wall, labyrinthine wall) is vertical, and has the oval window and round window, the promontory, and the prominence of the facial canal. Facing the outer ear , the lateral wall (or membranous wall ), is formed mainly by the tympanic membrane , partly by the ring of bone into which this ...
Patulous Eustachian tube is a physical disorder. The exact causes may vary depending on the person and are often unknown. [5] Weight loss is a commonly cited cause of the disorder due to the nature of the Eustachian tube itself and is associated with approximately one-third of reported cases. [6]
Hyperacusis is an increased sensitivity to sound and a low tolerance for environmental noise. Definitions of hyperacusis can vary significantly; it often revolves around damage to or dysfunction of the stapes bone, stapedius muscle or tensor tympani ().
The ear is built to function like a "conveyor belt" by sloughing off dead skin and earwax that naturally pushes its way out. This system tends to work well without much need for assistance.
