The cell body of a neuron is supported by a complex meshwork of structural proteins called neurofilaments, which are assembled into larger neurofibrils. Some neurons also contain pigment granules, such as neuromelanin (a brownish-black pigment, byproduct of synthesis of catecholamines) and lipofuscin (yellowish-brown pigment that accumulates with age).
They are also commonly known as neuroglia and even more simply glia. In more detailed terms, neuroglia are cells in your nervous system that are not neurons. Their role is to be the support team and cheerleaders for the neurons. The neuroglia: Form myelin, which wraps around axons to speed up electric impulse conduction ; Provide nutrients to your neurons, including oxygen ; Destroy pathogens ; Provide a general support structure on which neurons can sit ; In this lesson, we will focus on the neuroglia located in your central nervous system.
