NEET Biology question
Mark the following statements as true/false and choose the correct option from the codes given below I. Neuroglial cells are the packing and supporting cells found in the brain and spinal cord II. Oligodendrocytes is a category of glial cells that forms myelin sheaths around the axon III. Microglia provides mechanical support to the neurons IV. Astrocytes communicate with one another through potassium channels Codes
I | II | III | IV (a) True | True | False | False (b) False | True | True | False (c) False | False | True | True (d) True | False | True | False
Solution
Neuroglia are indeed the packing/supporting cells of the CNS (I, true), and oligodendrocytes are the glial cell type that forms the myelin sheath around CNS axons (II, true); microglia are instead phagocytic
