Mark the following statements as true or false. If a statement if false, correct it to make a true statement.


d. Spatial summation can combine two EPSPs, two IPSPs, or an EPSP and an IPSP.

A ________ is characterized by multiple input neurons synapsing on one postsynaptic neuron.

a. diverging circuit

b. discharge zone

c. facilitation zone

d. converging circuit

Mark the following statements as true or false. If a statement if false, correct it to make a true statement.

a. An excitatory postsynaptic potential is caused by K+ or Cl− channels opening in the membrane of the postsynaptic neuron.

Mark the following statements as true or false. If a statement if false, correct it to make a true statement.

b. Postsynaptic potentials may summate by spatial summation in which multiple neurons fire onto a single postsynaptic neuron.

Mark the following statements as true or false. If a statement if false, correct it to make a true statement.

c. An inhibitory postsynaptic potential causes the membrane potential of the postsynaptic neuron to approach threshold.

Explain how an action potential is propagated down an axon in continuous conduction. Why is saltatory conduction faster than continuous conduction?
