Nerve cell bodies stained with basophilic dyes show numerous microscopic clumps of Nissl substance (named after German psychiatrist and neuropathologist Franz Nissl, 1860–1919), which consists of rough endoplasmic reticulum and associated ribosomes. The prominence of the Nissl substance can be explained by the fact that nerve cells are metabolically very active, and hence are involved in large amounts of protein synthesis.

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).

There are different internal structural characteristics between axons and dendrites. Axons typically almost never contain ribosomes, except some in the initial segment. Dendrites contain granular endoplasmic reticulum or ribosomes, with diminishing amounts with distance from the cell body.

a neuron has a shaft called an axon and a nucleus inside a cell body. the axon is lined with myelin sheaths that connect to each other at the nodes of ranvier. there are dendrites on the cell body that receive neurotransmitters released by other neurons. at the end of the axon, there are little sacs that hold neurotransmitters that are eventually released to send signals to other neurons.

more or less the same things that are inside any other cell. the main difference are the voltage gated ion channels, but those are not even inside the neuron, they reside on the membrane
