Neurons and neuroglia are remarkable in this image showing the interconnecting cells and their supports (Chiras, 2011, p.78). This is a neuron which contains nucleus in its cell body that is responsible for synthesizing proteins and membranes while the axon conducts electrical impulse while the dendrites collect information (Hollenbeck and Bamburg, 2003). Satellite cells are situated in dorsal root ganglia somewhere in either side of the spinal cord and they enclosed cell bodies containing sensory neurons that are found inside the ganglia (Tiidus, 2008, p.77).
