What is the inner ear? The inner ear is an organ that combines two functions: hearing and the sense of balance. The inner ear is located in the petrous pyramid (part of the temporal bone) and is adjacent to the wall of the tympanic cavity, to which it is connected via the oval and round … Inner Ear: Structure, Function, Disorders
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 petrous bone is a bone and is part of the human skull. It is located at the base of the skull and is part of the temporal bone (Os temporale). In its pyramid-like basic shape lies the inner ear with the organ of equilibrium and the cochlea. Of clinical importance for the petrous bone … Petrous Bone: Structure, Function & Diseases
Spending time in space or flying airplanes under high stress requirements comes with some risks and can also become quite an ordeal. Bone and muscle loss, visual disturbances or circulatory problems are some of the manifestations that the physically demanding activity brings. For this purpose, aviation and space medicine was introduced, which deals specifically with … Aviation and Space Medicine: Treatment, Effects & Risks
Squamous epithelium refers to a specific type of body cell found on various external and internal body and organ surfaces. Squamous epithelium has covering or protective properties and is therefore also known as covering epithelium. What is squamous epithelium? Epithelial tissue is composed of cells lined up individually, but the shape and thickness of the … Squamous Epithelium: Structure, Function & Diseases
Otoliths are small granules of solid material that are responsible for sensing acceleration and gravity in all organisms. They are usually composed of calcium carbonate or starch. In mammals, including humans, calcite granules are located in the inner ear and regulate balance. What are otoliths? Otoliths are responsible for the sense of balance in mammals. … Otoliths: Structure, Function & Diseases
The vestibulospinal reflex is a brainstem reflex whose circuitry involves the vestibular organ and nuclei vestibulares. Activation of the reflex causes contraction of the extensor muscles while inhibiting the flexor muscles of the extremities. In decerebration rigidity, the reflex becomes prominent. What is the vestibulospinal reflex? A brainstem reflex is known as the vestibulospinal reflex, … Vestibulospinal Reflex: Function, Role & Diseases
The complexity of the human body is fascinating and unique. Even the smallest parts have their importance and justification. The following is a more detailed description of the earlobe in terms of its structure, function and potential problems. What is the earlobe? The human ear consists of the inner ear, middle ear and outer ear. … Earlobes: Structure, Function & Diseases
The cerebrospinal fluid space corresponds to a system of cavities in the central nervous system. In the so-called inner CSF space, the production of cerebrospinal fluid takes place, which is reabsorbed in the outer CSF space. Dilated CSF spaces give rise to pathological phenomena such as hydrocephalus. What is the cerebrospinal fluid space? Neurologists refer … CSF Space: Structure, Function & Diseases
Beethoven was undoubtedly one of the very great European composers. He composed some of his most famous works when he could only communicate with “conversation books” due to his deafness. His progressive hearing loss began when he was only 26 years old. Today, most researchers believe that its cause was otosclerosis of the inner ear. … Otosclerosis: Gradual Hearing Loss
The organ of balance, or vestibular apparatus, is located in pairs in the right and left inner ear. The three arcades, each perpendicular to the other, report rotational accelerations, and the otolith organs (sacculus and utriculus) respond to translational accelerations. Because of the physical mode of action, brief disorientations may occur after an acceleration or … Organ of Equilibrium: 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
