Label any neural parts you can clearly recognize.Draw your structures proportionately to their size in your microscope’s field of view. Two notable features distinguish the axon from the soma (also referred to as perikaryon). Localization: retinal cells and olfactory system. In the circle below, draw the neuron you found. Shape: one axon and one dendrite that extend from the cell body in opposite directions.Search carefully until you find a clear, representative neuron in your field of view. View the slide on the second-highest objective.Use any nervous tissue except peripheral nerve, there are no nerve cell bodies in a peripheral nerve section. Obtain a slide of nervous tissue from the instructor.In B, the neuron outlined in yellow illustrates a typical dendrite-cell body-axon arrangement. (CC-BY-SA-NC, University of Michigan Histology and Virtual Microscopy Learning Resources) Adjacent GnRH neuron dendrites were often found with plasmalaemma specializations between them, including punctae and zonula adherens, also known as attachment plates (Fig. In A, the neurons are too crowded to see any one neuron clearly. Labeled dendrites were found in close association with one another without any intervening elements in both animals (Fig. Neurons Dendrites Short-branched fibres that convert chemical information from other neurons or receptor cells into electrical signals Axon An elongated. Lined with a simple cuboidal-to-columnar epithelium of ependymal cells.\): Two different areas from the same slide of a nervous tissue preparation. Central Canal - small, round structure in the center of the spinal cord that contains cerebral spinal fluid.White Matter - surrounds the gray matter and contains ascending and descending axons (bundled into tracts) and supporting glial cells.
