What are the major types of glial cells in the adult vertebrate and describe the ways in which they nourish, support and regulate the functioning of the neurons.

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.

Conduction velocity refers to the [a] at which an action potential travels along a neuron's axon. In invertebrates, conduction velocity can only be increased by [b]. However in vertebrates (exclusively), such as humans, conduction velocity can also be increased by [c]. This enables vertebrates to conserve [d] while still increasing conduction velocity.

Describe and outline the function of sensory neurons, motor neurons, mutipolar neurons and glial cells

Enumerate and explain the features that lead to differential nerve impulse conductance in a bare plasma membrane versus an unmyelinated axon versus a myelinated axon.

What is affected by the electrical signal sent by the third structure? (This will be the fourth structure in the arc.) Where is the cell body of the fourth structure located? What is affected by the electrical signal sent by the fourth structure? (This will be the fifth structure in the arc.) What does the fifth structure do in response to that electrical signal and how does this action protect you? Describe a situation where a reflex arc would be activated that is not described in your lesson. Assume that the reflex arc has five components to it. Please choose a reflex that involves a body part below the neck. (If you have trouble with this, do an internet search for information on reflex arcs.)

List the components of the neuron and list the function of each part.  List the 6 glial cells, each of their functions, and whether they are found in the CNS of PNS.

Glial cells take care of neurons. Review the different types of glial cells by matching each description with the appropriate cell. You may use answers more than once. 1. Wrap around axons in the CNS:                                                                                              2. Wrap around axons in the PNS:   3. Regulate exchange of substances with capillaries and control interstitial space:   4. Surround, regulate, and protect cell bodies of neurons in the PNS:   5. Tiny macrophages that engulf unwanted substances and keep the CNS "clean":   6. Provide a supportive network:   7. Help produce cerebrospinal fluid at choroid plexus:

A biologist finds that a post-neuron responds to a pre-neuron’s AP in a mammal through a cell membrane pathway involving INTRACELLUAR Ca2+ RELEASE. Define what type of synapse this is and the specific possible mechanism (details!) about how binding the neurotransmitter on the post membrane causes this type of calcium release.

At rest, all gated Na+ and K+ channels are closed.Local currents __________ the axon, and voltage-gated Na+ channels __________, allowing Na+ ions to enter the cell. As the depolarization reaches threshold, this behavior becomes self-generating (as more Na+ rushes into the cell, the current causes more/neighboring voltage gated Na+ ion channels to open… positive feedback).
