Neuron (contents)
The following table lists the major components a typical neuron.
Component | Function |
---|---|
Nucleus | Contains the nucleolus and chromosomes |
Nissl substance | Consists of rough endoplasmic reticulum (with free ribosomes) and is the site of protein synthesis |
Golgi apparatus | Modifies, sorts, and packages macromolecules for cell secretion (exocytosis) or use within the cell |
Mitochondria | Involved in energy production |
Microfilaments and microtubules | Used for structural support and transportation within the cell |
Lysosomes | Spherical bodies containing digestive enzymes which break up cellular debris and protect against threats such as viruses |
Melanin | Function unknown, possibly a by-product of neurotransmitter synthesis |
