You are studying a cross-sectional tissue slice of a nerve using a transmission electron microscope. You find an area where there appears to be a small amount of cytoplasm surrounded by about 100 layers of stacked cell membranes. You conclude that you have found a neuron cell body. O a synapse. an unmyelinated axon. O a myelinated axon.
Suppose that a sensory neuron in the periphery generates a trainof action potentials, and synaptically excites an interneuronin the CNS. What does this signal mean? What additionalinformation does the interneuron need in order to decode themessage?
for the Spinothalamic Tract, can you show me a diagram for the pathway from the peripheral structures of the body to the location inthe brain.a. Label the location of each neuron's dendrites, cell body, and axon terminal.b. Label the location (nervous system region) of the synapses involved in this ascending pathway.c. Label the location (nervous system region) of decussations, if any.
Draw a simple summary diagram displaying the different levels of organisation of the nervous system. Include bullet points under each level to describe the function of that part. The bullet points should specifically include details of the role of that part of nervous system in homeostasis. no pics booklet in class
Describe what a graph of action potential amplitude vs stimulus intensity for a frog sciatic nerve would look like. What would be the x-axis label and units of measurement? What would be the y-axis label and units of measurement?
Select all of the statements from the list below that are true. Within a single axon, an action potential is always of the same magnitude. (In other words, it always looks the same on a trace of the membrane potential.) All excitatory post-synaptic potentials trigger an action potential. Graded potentials are always hyperpolarizing. The action potential always moves in one direction along an axon. Integration of sensory information is a major function of the central nervous system. All axons in the body are myelinated.
Multiple sclerosis is a demyelinating disease affecting the central nervous system. What type of cell would be the most likely target of this disease? Why? Which type of neuron, based on its shape, is best suited for relaying information directly from one neuron to another? Explain why. Sensory fibers, or pathways, are referred to as “afferent.” Motor fibers, or pathways, are referred to as “efferent.” What can you infer about the meaning of these two terms (afferent and efferent) in a structural or anatomical context?
You are investigating the effects of a newly discovered cell type. You have an intact synapse (including pre- and post-synaptic neurons) in a dish and observe what happens upon electrical stimulation. Following electrical stimulation of the pre-synaptic neuron, you record an action potential in the pre-synaptic neuron and an EPSP in the post-synaptic neuron. The synapse most likely utilizes which of the following neurotransmitters? Sodium (Na++) GABA Calcium (Ca++) Glutamate
What function do unipolar neurons provide and where is their cell body found? They are motor neurons with their cell body in the central nervous system They are sensory neurons with their cell body located in the central nervous system They are motor neurons with their cell body located outside of the central nervous system They are sensory neurons with their cell body located outside of the central nervous system
Does the action potential in a single axon increase in amplitude when the stimulus amplitude is increased? Does the amplitude of the CAP increase because more fibers are firing, or the amplitude of the action potentials from single fibers are increasing, or a combination of both?
Do Excitatory Potentials (EPSPs) and Inhibitory Potentials (IPSPs) only come into play at the synapses due to the NT's that bind to receptors on post-synaptic cell? And if an action potential is fired in the post-synaptic cell will it propagate from node to node dependent of this concept or do EPSPs and IPSPs come into play at each section of the axon?
