Nissl bodies are best described as what cellular feature in neurons?

Explanation:
Nissl bodies are clusters of rough endoplasmic reticulum with ribosomes in neurons, specialized for protein synthesis. This makes them basophilic when stained and concentrated in the cell body and proximal dendrites. They are not mitochondria (which generate energy) or the Golgi apparatus (which modulates and ships proteins). They’re also more than just ribosomes alone; the ribosomes are bound to the endoplasmic reticulum, forming the dense Nissl substance that supports the neuron’s production of proteins needed for growth, maintenance, and neurotransmitter function.
