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.
A neuron consists of a cell body (perikaryon) and its processes, an axon and one or more dendrites. Neurons function in the initiation and conduction of impulses. They transmit impulses to other neurons or cells by releasing neurotransmitters at synapses. a nerve cell; the basic structural unit of the nervous system. There is a wide variation in the shape of nerve cells, but they all have the same basic structures: cell body, protoplasmic processes, axons, and dendrites. The neuron is the only body cell whose principal function is the conduction of impulses.
