Earwax helps protect the ear by trapping dust and other foreign particles that could filter through and damage the eardrum. [5] Normally, earwax moves toward the opening of the ear and falls out or is washed away, but sometimes excessive earwax can gather and become hard to remove. This is referred to as excessive earwax or impacted cerumen. [21]
Smell, or olfaction, is a chemoreception that forms the sense of smell. Olfaction has many purposes, such as the detection of hazards, pheromones, and food. It integrates with other senses to form the sense of flavor. [8] Olfaction occurs when odorants bind to specific sites on olfactory receptors located in the nasal cavity. [9]
Phantosmia (phantom smell), also called an olfactory hallucination or a phantom odor, [1] is smelling an odor that is not actually there. This is intrinsically suspicious as the formal evaluation and detection of relatively low levels of odour particles is itself a very tricky task in air epistemology.
Odor or discharge in the ear. Pain or infection in the ear. The back of a Q-tips box contains a warning against putting Q-tips in the ear canal, stating that they should be swabbed "gently around ...
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.
If you notice your dog pawing at their ears, smell a foul odor coming from their ears or notice any oozing, you should take them to a vet to get checked out. These are all signs of a possible ...
The phenotypes expressed by the genotypes include cerumen type (wet or dry ear wax), osmidrosis (odor associated with sweat caused by excessive apocrine secretion), and possibly breast cancer risk, although there is ongoing debate on whether there is a real correlation of the wet ear wax phenotype to breast cancer susceptibility.
Age is the strongest reason for olfactory decline in healthy adults, having even greater impact than does cigarette smoking. Age-related changes in smell function often go unnoticed and smell ability is rarely tested clinically unlike hearing and vision. 2% of people under 65 years of age have chronic smelling problems.
