Webb28 apr. 2024 · The Nissl bodies contain clusters of Rough Endoplasmic Reticulum (RER) and free ribosomes. The cell body is another term for the soma of a neuron. The Axolemma is the membrane of the axon. The endothelial cell is a cell that forms the blood-brain barrier. The Telodendria is a fine branch of the axon. WebbThe ribosomes are not organized into Nissl bodies and are too sparsely distributed to produce basophilia. They vanish at the end of the initial segment. Fascicles of microtubules occur only in the axon hillock and initial segment and nowhere else in the neuron. Therefore, they are the principal identifying mark.
Webb1 aug. 2024 · Molecularly, Nissl bodies are the densely clustered ribosomes on the ER. The basophilia is due to the RNA in the ribosomes. The question you have raised is a very significant one.
