Chapter 35

Name the three basic types of neuron and describe their functions.

Diagram and label the basic features of a neuron, indicating where information is received and where it is sent.

Explain what is meant by saying action potentials are "all-or-nothing."

Explain why action potentials propagate along an axon only in a single direction.

Briefly describe how myelinated axons increase the speed of signal transmission.

Describe how temporal summation of EPSPs from two presynaptic neurons results in a larger depolarization of the postsynaptic cell compared with how an inhibitory presynaptic neuron causes an IPSP that negates the EPSP of an excitatory neuron, and how spatial summation of three excitatory presynaptic neurons produces an even larger depolarization of the postsynaptic neuron.

List which functions of an animal are controlled by voluntary and by involuntary components of the nervous system.
