Overview of Nervous System

• List the general functions of the nervous system.
• Explain the structural and functional classifications of thenervous system.
  • Distinguish between the CNS, PNS, and ANS
• Describe the general structure of a neuron and name itsimportant anatomical regions (dendrites, axon, axonalterminals)
• Differentiate between sensory, motor neurons and interneurons
  • Name the specific types of neurons that connect the CNS withskeletal muscles, sensory receptors, the heart, smooth muscle, andglands
• Identify different types of glia cells and explain theirfunctions (astrocytes, Schwann cells, oligodendrocytes, microglia,ependymal cells)
• Explain the significance of the blood-brain barrier (how is itformed, what type of molecules can pass through)

Action Potentials

• Explain what a resting membrane potential is and how it isformed
• Explain in detail what happens during an action potential,where it is formed and its characteristics
• Explain the terms depolarization, repolarization andhyperpolarization
• Describe the mechanism that allows information to travel inonly one direction in an axon
• Explain how intensity (stimulus strength) is neurally encoded
  • Explain the relationship between the amplitude of the actionpotential and the stimulus intensity.
• Differentiate between the absolute and refractory periods
• Explain the effect of myelination and axonal diameter on theconduction velocity
  • Explain how the conduction speed changes between A, B and Cfibers
• Differentiate between all-or-none (action potentials) andgraded potentials
• Distinguish between temporal and spatial summation
• Explain EPSPs, IPSPs and how they contribute to generation ofan action potential
• Describe the effect of tetrodotoxin and lidocaine on thevoltage-gated Na+ channel.

Synapses

• Identify the structures of a synapse (presynaptic neuron,postsynaptic neuron, synaptic cleft, vesicle, neurotransmitter,receptor)
• Explain synaptic transmission and the role of calcium ions inneurotransmitter release.
  • Explain the effect of magnesium ions in neurotransmitterrelease.
• Explain the location, function and importance of the followingin an ACh synapse: action potential, voltage-gated Ca2+ channels,Ca2+, vesicles, acetylcholine neurotransmitters, exocytosis,diffusion, ACh receptor, ion channel of ACh receptor, Na+, K+,acetylcholinesterase
