The Scientist: Olfactory Organoids Sniff Out the Cells That Help Us Smell
The signaling mechanisms underlying the transition from stem cells to olfactory neurons has been described. Cellular differentiation of stem cells into specialized cells requires many steps, including ...
MSN: Sniffing out how stem cells become olfactory neurons in living animals
Expanding the understanding of what causes anosmia The long-standing belief within the medical community is that the primary cause of anosmia is damage to olfactory sensory neurons. The fine nerve fibers, which travel through bone to connect the olfactory bulb to the nasal epithelium, are vulnerable to trauma and viral infections.
An olfactory hallucination, known as phantosmia, makes you detect smells that aren't in your environment. The odors you notice in phantosmia are different from person to person and may be foul or pleasant. You may notice the smells in one or both nostrils. The phantom smell may seem to always be ...
Esthesioneuroblastoma (es-thee-zee-o-noo-row-blas-TOE-muh) is a rare type of cancer that starts in the upper part of the inside of the nose, known as the nasal cavity. Esthesioneuroblastoma also is called olfactory neuroblastoma. This cancer usually affects adults. But it can occur at any age ...
A stuffy nose from a cold is a common cause for a partial, brief loss of smell. A polyp or swelling inside the nose can lead to a loss of smell. Aging can cause a loss of smell, especially after age 60. What is smell? The nose and an area in the upper throat have special cells, called receptors, that discern odors. These receptors send a message to the brain about each smell. The brain then ...
