Which of these structures is present in both non-myelinated and myelin

1.	Which of these structures is present in both non-myelinated and myelinated neurons?(a) Myelin forming Schwan cells(b) Myelin sheath(c) Nissl’s granules(d) Nodes of RanvierThis question was addressed to me in class test.My question is from Neuron-1 in section Neural Control and Coordination of Biology – Class 11
Answer» Correct option is (c) Nissl’s granules For explanation: Non-myelinated neurons lack myelinated AXONS. Hence, myelin FORMING Schwan cells, which surround and form myelin, are absent. Nodes of Ranvier are also absent as they are the POINTS between two adjacent myelin SHEATHS.
