Label a neuron, classify it by processes and by function, match each neuroglial cell to its job, and explain what myelin and the nodes of Ranvier do for conduction.
Nervous tissue closes unit 3 and overlaps with unit 5, so a question here is usually about the cells rather than the brain. MEC's scope line is "Structure, location and function". Recall items ask which cell makes myelin in the brain, what Nissl granules are, or where bipolar neurons occur. Understanding items ask why myelinated fibres conduct faster, why a cut nerve in the arm regrows while a cut spinal cord does not, or why glia rather than neurons form brain tumours. Application items describe a demyelinating disease, an injured axon or a slide. Learn the neuron first, then the six glial cells with one job each.
