What is the significance of Nissl bodies? How are Nissl bodies different from any other RER seen in any other cell of the body?
I am going to try answer this question.
This basophilic substance was just only find in dendrites of neurons, not axones. It is composed by RNA polyribosomes.
Basicly i am tring to tell you that Niessle body is just older name from old ages of histology.
Niessel body is not diffrent with others rought endoplasmatic reticulum(RER). It same pourpose as normal RER.
