Learning Objectives Use the animal phylogeny to compare nervous systems across the animal phylogeny. Use your knowledge of body plan in animals to make predictions about nervous systems in diverse animals. Name the parts of the vertebrate nervous system, consisting of the central nervous system, peripheral nervous system, sensory receptors, and effector cells. Draw the basic structure of a neuron: axon, dendrites, cell body, synaptic terminals, and synapse Explain, in your own words, the meaning of the term “membrane potential.” Explain, in your own words, how membrane potential and voltage-gated Na+ and K+ channels change during an action potential. Predict how defects or attacks on the “action- potential machinery” would impact the ability of a neuron to generate an action potential. Explain, in your own words, why an action potential propagates, including why the
