- Stellate cells initially process sensory input to the cortex, whereas pyramidal cells send fibers from the cortex to terminate on efferent motor neurons. (True or false)Many neurons have only a single axon, but many terminals at the end of the axon. How does this end structure of the axon support its function?If the plasma membrane of an electrically excitable cellwere depolarized to threshold in the center of the axon orsarcolemma, would the action potential be propagated inonly one direction? Why or why not?
- Areas of myelinated axons create the appearance of _______ matter, while neuron cell bodies and unmyelinated axons create the appearance of ______ matter.Why is that if A, B, and D neurons were all activated, an action potential in neuron C would not occur. But if A and D were activated, an action potential in C would occur?In what way does the interior surface of the cell membrane of a resting (non-conducting) neuron differ from the external environment? The interior is: positively charged and contains less sodium. negatively charged and contains less sodium. negatively charged and contains less potassium positively charged and contains more sodium.
- "Hebb's Rule" says, in effect, that a neuron that is repeatedly activated will have an increasingly powerful effect on all of its neighbours. neurons that are repeatedly activated together become more strongly connected. neurons that are strongly connected are likely to become activated at the same time. neurons that are strongly connected are typically found in the cortex.Suppose you placed an isolated neuron in a solution similar toextracellular fluid and later transferred the neuron to a solution lackingany sodium ions. What change would you expect in the resting potential?What are the three mainparts into which a neuron canbe divided? What are theirrespective functions?
- Distinguish between convergence and divergence in a neuronal pool.Compare and contrast the neuroglial cells that form the myelin sheaths in both the CNS and the PNS?With respect to the three structural types of neurons (unipolar, bipolar & multipolar): State which parts of each type of neuron receive information, which parts integrate information, and which parts conduct the output signal of the neuron. Describe the location of the cell bodies of each type of neuron within the nervous system.
