Which type of cells in the nervous system provide support and nourishment to neurons?

Glial cells, also known as neuroglia or simply glia, are the type of cells in the nervous system that play a crucial role in supporting and nourishing neurons. Unlike neurons, which are primarily responsible for transmitting electrical signals and processing information, glial cells serve several supportive functions.

They help maintain homeostasis, form myelin for insulating axons, and facilitate synaptic function, which is essential for the effective communication between neurons. Furthermore, glial cells assist in the repair and regeneration of nervous tissue and help protect neurons from pathogens and injury. This supportive role is vital for the overall health and efficiency of the nervous system.

In contrast, neurons are the primary signaling cells in the nervous system and are responsible for communication, while axons and dendrites are parts of neurons that carry signals away from and towards the cell body, respectively. These structures are integral to neuronal function but do not provide the supportive role that glial cells specialize in.
