Bio1152 Chapter 48 Neurons, Synapses, and Signaling
  1. Nerve cells called          coordinate information transfer within the body of a multicellular animal and often make up a          system with different types of neurons.

    Neuron Structure exercise:
  2. Neurons maintains a voltage across its plasma membrane called a          potential of about -70 mV.

  3. A stimulus may trigger a graded                 that can yield an         potential of about 30 mV.

  4. An action potential is regenerated along an       to a synaptic terminal.

    Action Potential tutorial:
  5. Many axons are insulated by a         sheath formed by Schwann cells, allowing action potentials to jump in a process called            conduction.

  6. Most neurons communicate with other cells at chemical           , where a presynaptic neuron releases chemical                    stored in the synaptic terminal.

  7. Postsynaptic potentials are         and can be either              postsynaptic potentials (EPSPs) or             postsynaptic potentials (IPSPs).
