11: Fundamentals of the Nervous System and Nervous Tissue Objectives Functions and Divisions of the Nervous System 1. List the basic functions of the nervous system. 2. Explain the structural and functional divisions of the nervous system.  Histology of Nervous Tissue 3. List the types of neuroglia and cite their functions. 4. Define neuron, describe its important structural components, and relate each to a functional role.  5. Differentiate between a nerve and a tract, and between a nucleus and a ganglion.  6. Explain the importance of the myelin sheath and describe how it is formed in the central and peripheral  nervous systems.  7. Classify neurons structurally and functionally. Membrane Potentials 8. Define resting membrane potential and describe its electrochemical basis.  9. Compare and contrast graded potentials and action potentials. 10. Explain how action potentials are generated and propagated along neurons.  11. Define absolute and relative refractory periods.  12. Define saltatory conduction and contrast it to conduction along unmyelinated fibers.  The Synapse 13. Define synapse. Distinguish between electrical and chemical synapses by structure and by the way  they transmit information. 14. Distinguish between excitatory and inhibitory postsynaptic potentials. 15. Describe how synaptic events are integrated and modified. Neurotransmitters and Their Receptors 16. Define neurotransmitter and name several classes of neurotransmitters. Basic Concepts of Neural Integration 17. Describe common patterns of neuronal organization and processing. 18. Distinguish between serial and parallel processing. Chapter 11 Fundamentals of the Nervous System & Nervous Tissue I. Intro       A.  Chapters 11-15 take us into the world of communication, coordination and integration.   While  the nervous system accounts for a mere 3% of the total body weight, it is by far the  most complex  organ system and the most complex aggregate of matter on planet Earth.   It may be the last frontier  in our  understanding of the human body.  It is, for sure, the  most challenging system for A & P

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
