Basic phenotypic characteristics of nerve cells Options

[Graeber]

Neurons exist in a variety of shapes. In other words, there is no prototypical nerve cell. Considering all the different morphologies and sizes of sensory or autonomic ganglion cells, motor neurons, Purkinje cells, granule cells, cortical interneurons or pyramidal cells, it is surprising that they are all built for the same purpose: to receive, process and transmit information by means of bioelectrical signaling. Neurons share the features of basic metabolism, cytoarchitecture, organelles and functional cell biology with other somatic cells. The typically spherical nucleus shows relatively little heterochromatin and contains one or even two nucleoli. There are mitochondria, lysosomes, Golgi complexes and a rough endoplasmic reticulum (RER) arranged in the form of Nissl bodies.
