Describe how information is passed from the pre-synaptic to post-synaptic neuron in order to allow information flow throughout the nervous system.

Expert Solution

The process by which this information is communicated from the pre synaptic to post synaptic neuron is known as synaptic transmission.The neuron before the synapse is known as the presynaptic neuron which communicates with the neuron after the synapse which is known as the post synaptic neuron via chemical signals.Neurotransmitters are released by the presynaptic neuron that diffuse across the synaptic cleft i.e gap between neurons and bind to receptors on the postsynaptic neuron.This stimulates the initiation of an electrical impulse in the postsynaptic neuron that passes on the information.Overall, it can be divided into four steps.

The first step involves the synthesis and storage of the neurotransmitters in vesicles on the terminal end of pre synaptic neuron. .
When an action potential reaches the presynaptic neuron. the neurotransmitter is released into the synaptic cleft.
The neurotransmitter is recognised and binds to specific receptors on the postsynaptic cell.
After the receptor is bound by neurotransmitter,the information is passed to the post synaptic neuron and a new action potential is generated.

If a pre-synaptic neuron released a neurotransmitter onto a post-synaptic neuron and caused potassium (K+) channels...

If a pre-synaptic neuron released a neurotransmitter onto a post-synaptic neuron and caused potassium (K+) channels to open, what effect would this have on the post-synaptic neuron? A. the post-synaptic neuron would likely generate an inhibitory post-synaptic potential (IPSP) B. the post-synaptic neuron would likely generate an excitatory post-synaptic potential C. the post-synaptic neuron would likely release a neurotransmitter D. the post-synaptic neuron would likely produce an action potential

Describe what causes excitatory and inhibitory post-synaptic potentials, and how each affect a post-synaptic neuron.

What is the role of acetylcholinesterase at a synapse? It stimulates the post-synaptic neuron. It breaks down acetylcholine. It releases calcium ions. All apply.

A single post-synaptic neuron has two axon terminals synapsing with it. When only the first terminal releases transmitter, the post-synaptic neuron fires an action potential. However, when both terminals fire simultaneously, the post-synaptic neuron does not fire an action potential. How can you explain this?

Describe the events of synaptic transmission in proper chronological order from the release of neurotransmitter by synaptic vesicles to the effect of the neurotransmitter on the postsynaptic cell.

Describe the development of the eye and the distinct neuron pathways that allow for the complex processing of visual information. What is the optic placode and where does it originate? The temporal and nasal retinal fields are distinctly innervated. What causes the embryological difference between these structures? How does neuronal pathfinding work, both in general and in the optic nerve specifically? What causes decussation in the optic chiasm? Why do only some of the neurons decussate? How does the brain...

in C programming Write the code to traverse the binary tree using in-order, post-order and pre-order methods. Make sure to validate that your output is correct. Review the terminology for tree structures and list structures. What is the root of the tree, what’s a parent, what’s a child, what’s an ancestor, what is an external node, what is an internal node, what is the head of the list, what is the tail of the list, etc. Traverse the binary tree...
