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.

  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.

  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).
