EXERCISE 17 – NERVOUS TISSUE OBJECTIVES 1. To differentiate between the neurons and neuroglia. 2. To identify the neuroglial cells—microglia, astrocytes, and Schwann cell. 3. To classify neurons according to structure and function. 4. To identify the important structures of a neuron, and state the functions of each. 5. To explain how a nerve impulse is transmitted via the synapse. 6. To explain the role of Schwann cells in the formation of the myelin sheath. 7. To describe the structure of a nerve and identify the connective tissue coverings. NOTES: 1. I. Functional classification of neuron: Sensory neurons - afferent Interneurons Motor neurons - efferent II. Structural classification of neuron: Unipolar neurons Bipolar neurons Multipolar neurons 2. Types of neuroglia cells: Astrocytes Ependymal cells Microglia Oligodendrocytes Schwann cells Satellite cells 3. General structure of a neuron: cell body with Nissl bodies dendrites
