- Neurofibromatosis type 1
NF1, a genetic disorder characterized by a number of remarkable skin findings including multiple cafe au lait (coffee with milk) spots, multiple benign tumors called neurofibromas on the skin, plexiform neurofibromas (thick and misshapen nerves due to the abnormal growth of cells and tissues that cover the nerve), and freckles in the armpit and groin. […]
- Neurofibromatosis type 2
A genetic disorder that is characterized by the growth of benign tumors of both acoustic nerves (the nerves to the ears). These tumors, called acoustic neuromas, cause tinnitus (ringing in the ears), hearing loss, and problems with balance. Abbreviated NF2. Other findings in NF2 include similar benign tumors of other nerves, meningiomas, and juvenile cataracts. […]
- Neurogenesis
The process by which new nerve cells are generated. In neurogenesis, there is active production of new neurons, astrocytes, glia, and other neural lineages from undifferentiated neural progenitor or stem cells. Neurogenesis is considered a rather inactive process in most areas of the adult brain.
- Neurogenic
Giving rise to or arising from the nerves or the nervous system. For example, neurogenic pain is pain that originates in the nerves, as opposed to muscle pain, bone pain, etc.
- Neurogenic shock
A type of shock (a life-threatening medical condition in which there is insufficient blood flow throughout the body) that is caused by the sudden loss of signals from the sympathetic nervous system that maintain the normal muscle tone in blood vessel walls. The blood vessels relax and become dilated, resulting in pooling of the blood […]
