Middle ear infection or otitis media is a painful disease in the area of the middle ear. It can occur acutely, as well as chronically. Triggers are mostly bacteria and viruses. Otitis media often occurs in young children. Typical signs are earache, hearing loss, fever and fatigue. A middle ear infection should be distinguished from … Otitis Media: Causes, Symptoms & Treatment
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
Electrostimulation involves contacting a motor nerve by means of applied voltage. This contacting causes an action potential to reach the muscle, causing it to contract. Therapeutic electrostimulation is used primarily for peripheral paralysis and is intended to prevent muscle atrophy. What is electrostimulation? Electrostimulation is therapeutic stimulation by an applied voltage source. Electrostimulative procedures are … Electrostimulation: Treatment, Effects & Risks
Endolymph is a clear potassium-rich lymphoid fluid that fills the cavities of the membranous labyrinth in the inner ear. Separated by the Reissner membrane, the membranous labyrinth is surrounded by the sodium-rich perilymph. For hearing, the different ion concentration between perilymph and endolymph plays a major role, while the mechanical-physical properties (principle of inertia) are … Endolymph: Structure, Function & Diseases
The language center consists primarily of the Wernicke and Broca areas in the cortical region of the cerebrum and frontal lobe. While the Wernicke area is responsible for semantic language processing, Broca’s area is primarily responsible for syntactic and grammatical language production. Inflammation– or hemorrhage-related damage in one of the areas manifests in speech comprehension … Language Center: Structure, Function & Diseases
Speech is a basic function of human communication and distinguishes humans from any animal in this area. Human speech in this mature form does not occur in the animal kingdom and is a unique, highly accurate mode of communication among humans. What is speech? Speaking is the core of human communication. While gestures, facial expressions … Speech: Function, Task & Diseases
Many people will immediately raise their hands defensively when hearing or reading the phrase diet and nutrition in liver disease, because they believe that a dietary prescription consists only of prohibitions. This is not infrequently due to the fact that, up to now, the doctor usually put a large number of foods on a forbidden … Diet and Nutrition in Liver Disease
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
Brodmann areas are a division of the human cerebral cortex based on cellular architecture. Areas with the same cellular structure form a Brodmann area. The brain is divided into 52 Brodmann areas. What is a Brodmann area? The brain of all living things appears as a monotonous and fatty mass, therefore white in color. Although … Brodmanns Area: Structure, Function & Diseases
Synonyms Hearing, ear, hearing organ, sense of hearing, sense of hearing, acoustic perception, auditory perception, Definition Hearing/human hearing is our best trained sense. This means that we are able to distinguish, for example, twice as much as we can with visual impressions: From more than 24 frames per second on, we no longer recognize individual … Listen to
The human face is capable of illustrating expressions of emotion through facial expressions, which is made possible with the multitude of muscles found in the face. Because of the versatile features and the many sensitive parts that the face contains, various forms of disease can occur. The medical aspects of the face are outlined below. … Face: Structure, Function & Diseases
