Download Review sheet exam 2

1 ) Explain in detail how a neuron fires an action potential.
Include ion channels, membrane pumps, ion movements, and
membrane potentials.
2) Explain in detail how one neuron signals another across a
synapse. Include ion channels, membrane pumps, ion
movements, and membrane potentials.
3) Draw a diagram that illustrates the complete pathways
used by a protein hormone to signal the inside of a cell. Do
the same for a steroid hormone.
4) Compare the nervous and endocrine systems with respect
to anatomy, chemical messengers, speed and major
functions.
5) Describe the protective system (structures) of the brain.
Include bones, ventricles, tissues etc..
6) Explain how reflexes work. What types of neurons, ion
channels, and receptors are involved? How do neurons
integrate information (EPSP, IPSP, Summation etc…)
7) List out the major structures of the CNS and give the basic
function for each. How did the videos shown in class
reinforce your understanding of the function of each area?
What are the basic cells found in the nervous system?
8) List the cranial nerves in order and describe the basic
function of each.
9) What is the difference between a sensation and a
perception?
10) What are the different types of sensory receptors found
in the PNS? How do tonic and phasic receptors work and
compare to each other?
11) How is sensory information coded as it moves from the
PNS to the CNS?
12) Compare the characteristics of fast and slow pain
pathways. What transmitters are involved?
