In the middle ear of the human ear, there are three ossicles that are hinged together and transmit the mechanical vibrations of the eardrum to the cochlea in the inner ear. The middle ossicle is called the incus. It receives the vibrations of the hammer and transmits them to the stapes with mechanical amplification. Although … Anvil: Structure, Function & Diseases
The organ of Corti is located in the inner ear in the cochlea and consists of supporting cells and sensory cells responsible for hearing. When a sound wave excites the hair sensory cells, they trigger an electrical signal in the downstream neuron that travels to the brain via the auditory nerve. Diseases that can affect … Organ of Corti: Structure, Function & Diseases
The Bing test is one of several well-known subjective hearing test procedures that use certain tuning fork tests to detect whether a unilateral sound conduction or sound perception disorder is present when hearing is diminished. The Bing test uses the difference in hearing sensation between bone and airborne sound when the external auditory canal is … Bing Test: Treatment, Effect & Risks
By the tympanic cavity, physicians mean a cavity of the middle ear in which the auditory ossicles are housed. In addition to the hearing process, the tympanic cavity is involved in middle ear ventilation and pressure equalization. Tympanic effusion is the most well-known complaint associated with the tympanic cavity. What is the tympanic cavity? The … Tympanic Cavity: Structure, Function & Diseases
Bone tissue is a particularly strong connective and supporting tissue. It forms the human skeleton. There are between 208 and 212 bones in the body that are made up of bone tissue. What is bone tissue? Bones are made up of different tissues. Bone tissue is what gives bones their stability. It belongs to the … Bone Tissue: Structure, Function & Diseases
The Rydel-Seiffer tuning fork is an (almost) normal tuning fork with fundamental frequencies of 64 and 128 Hz, the natural C and c vibrations, which differ slightly from the concert pitch vibration commonly used today, which is based on the concert pitch a at 440 Hz. The Rydel-Seiffer tuning fork is used to diagnose functional … Rydel-Seiffer Tuning Fork: Applications & Health Benefits
The auditory nerve is one of the most important nerves, as it is responsible for transmitting acoustic information to the brain. If its function is disturbed – this can happen, for example, due to infections of the inner ear, strong noise or circulatory disorders – the hearing ability of the affected person is reduced. In … Auditory Nerve: Structure, Function & Diseases
In order for us to hear sounds, a finely tuned interaction of different areas of the inner ear is necessary. In this process, the cochlea is the switching point to the brain. What is the cochlea? The cochlea is the actual hearing organ in the inner ear. It is made up of special hair sensory … Auditory Cochlea: Structure, Function & Diseases
Various tuning fork tests are used to detect functional impairment of peripheral nerves and to identify and differentiate hearing problems according to conductive and sensorineural disorders. Medical offices usually use a specialized tuning fork that vibrates at 128 hertz for hearing tests and at half the frequency, 64 hertz, for vibration tests of the nerves … Tuning Fork Test: Treatment, Effect & Risks
Blood in the ear, even if it seems bad at first, is absolutely harmless in most cases. Often the bleeding is caused by small injuries caused by incorrect or improper ear cleaning. More rarely, a more serious disease is the cause of bleeding in the ear. What is blood in the ear? In most cases, … Blood in the Ear: Causes, Treatment & Help
Audiometry is used to examine and measure functional parameters of the auditory organ and to delineate sound conduction and sound perception disorders. The variety of procedures used covers a wide spectrum from simple tuning fork tests to complex subjective and objective sound and speech audiometric procedures. Objective procedures also include electrical brainstem audiometry for objective … Audiometry: Treatment, Effect & Risks
The middle ear amplifies sound waves that arrive at the eardrum and cause it to vibrate. This is necessary because the sensory cells in the inner ear are embedded in fluid, and sound is perceived less strongly in fluid (you know the effect when you are immersed in the bathtub). How is the amplification achieved? … Inner Ear: Functions
