- Synapses through interconnected neurons are known to be a junction that mediates information transfer from one neuron to the other neurons. Enumerate and describe the classifications of synapses based on what you can research on online. Kindly include your reference.arrow_forwardDemyelination is the loss of myelin from neurones that are normally myelinated. Multiple sclerosis is a disease in which demyelination occurs in neurones involved in coordinating muscle movement. Using your knowledge of nerve impulse generation and propagation, explain how nerve impulse generation and propagation would be affected in people who have multiple sclerosis. The explanation needs to be in the form of a step by step sequence of annotated drawings. This could be in the form of an annotated cartoon/picture strip. Compare this to nerve impulse generation and propagation in an individual who does not have multiple sclerosis.arrow_forwardNeuron 1 fires an action potential, releasing neurotransmitters to neuron 2. However, neuron 2 does not fire an action potential itself. Write: Explain two possible reasons for neuron 2 not firing.arrow_forward
- Because the long axons of neurons look like electrical wires, and both neurons and electrical wires conduct electricity, it is tempting to equate the two. Compare and contrast the functioning of axons and electrical wires in terms of their structure and the nature of the electrical signals they conduct.

- In the sympathetic division of the autonomic nervous system: Select one: The ratio between the number of postganglionic and preganglionic neurons is small. A single preganglionic neuron usually synapses with a single postganglionic neuron. An important functional characteristic is convergence of the preganglionic fibers. Preganglionic fibers are usually much longer than the postganglionic fibers. Activity of the neurons tends to have a more generalized and widespread effect on the body.arrow_forwardDescribe how an action potential in the presynaptic neuron is generated in the postsynaptic neuron. Label the presynaptic neuron, postsynaptic neuron and synapse. Explain what is happening in figure on the left. Use key terms in order AND label on diagram: presynaptic axon terminal, action potential, calcium, vesicle, neurotransmitters, synapse Explain what is happening in the figure on the right.
