Unit 7: Animal Form and Function Neurons, Synapses, and Signaling Review
  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).
