Neuronal morphology - Cell body

4 important questions on Neuronal morphology - Cell body

How can you distinguish neurons and glial cells under the microscope?

Neurons are big cells with big cell bodies and fibers leaving the cells, while glial cells are the little dots around the neurons.

Why do neurons have a prominent nucleolus?

Nucleolus is essential for growth of developing neurons, neurite morphogenesis and long-term maintenance of mature neurons.

Why do neurons require a lot of RER (rough endoplasmic reticulum)?

They produce a lot of secretory proteins (neurotransmitters) and they constantly need to communicate action potentials to other neurons. Which require a large amount of RER.
