Nissl granules are the collection of:
Correct answer: C. ribosome and endoplasmic reticulum
- A. endoplasmic reticulum
- B. golgi bodies
- C. ribosome and endoplasmic reticulum
- D. mitochondria
- E. lysosomes
Explanation
Correct. Nissl granules consist of rough endoplasmic reticulum (RER) and ribosomes, which are essential for protein synthesis in neurons.

About Neurons and Nerve Impulse
Neurons receive and transmit information through dendrites, the cell body and axons. The topic explains resting potential, depolarization, repolarization, refractory periods and saltatory conduction, followed by synaptic transmission through neurotransmitters. An action potential is distinct from the graded potential produced at a receptor.
