What is the cell body of neurons consisting from?

--a nucleus (most neurons possess in the middle of their cell body a single large spherical nucleus containing a large dense rounded nucleolus, visible in optical microscopy), --a prominent Golgi apparatus --many mitochondria --well-organized cytoskeleton that maintains the shape of the neuron and allows specific functions such as axonal transport --a smooth endoplasmic reticulum (SER) --Nissl bodies: in optical microscopy it is a very basophilic material in the form of fine granulations. In electron microscopy these granulations correspond to RER cisternae, between which there are numerous free ribosomes reflecting the intense activity of protein synthesis. The neuronal cytoskeleton is composed of actin microfilaments, microtubules (MT) and neurofilaments (NF). Neurofilaments are specifically axonal.
