Nursecells

Nursecells, also known as sustentacular cells, are a type of glial cell found in the nervous system. Their primary function is to support and nourish neurons. They are particularly abundant in the olfactory epithelium, where they play a crucial role in the sense of smell. In this location, they are believed to contribute to the maintenance of the olfactory sensory neurons, protect them from environmental damage, and help clear away debris and pathogens.

Beyond the olfactory system, nursecells are also found in other neural tissues, including the peripheral nervous system. Their supportive role extends to providing structural integrity and metabolic assistance to nerve cells. They can influence neuronal survival and function through various mechanisms, including the release of growth factors and signaling molecules. The term "nursecell" highlights their essential, nurturing role in maintaining the health and functionality of the nervous system, ensuring the proper transmission of neural signals. Their multifaceted support is critical for the overall operation of neural circuits.
