West Coast University Nervous System Options Discussion
Comment to this topicsTopic 1:Phenytoin (sodium channel blocker) and ethosuximide (calcium channel blocker) are anti-seizure drugs that stop seizures from happening. These drugs work by inhibiting electrical impulses (action potentials) from occurring. Explain the importance of sodium and calcium channels on a neuron and and the reasons why action potentials do not occur when these channels are inhibited. Be sure to include the phases of an action potential, the channels involved, and the importance of an action potential.Be detailed in your explanation and support your answer with facts from your textbook, research, and articles from scholarly journals. In addition, remember to add references in APA format to your posts to avoid plagiarism.Topic 2:The hormone leptin regulates food intake and body weight. It can cross the blood-brain barrier. Search PubMed (www.pubmed.gov) for blood-brain barrier and leptin and select two original research articles about leptin. Summarize the results of these articles. Which proprieties of leptin allow it to cross the blood-brain barrier? How does leptin regulate energy balance?Be detailed in your explanation and support your answer with facts from your textbook, research, and articles from scholarly journals. In addition, remember to add references in APA format to your posts to avoid plagiarism.Comment- reply to thisSeizure is a sudden burst of uncontrolled electrical activity in the brain that occurs when neuron becomes excessively active. Seizure is a result of an imbalance between inhibitory and excitatory process in the brain that produces either too little inhibition or too much excitation. The main form of communication among neuron occurs through the action potential which is the travelling wave of electrical excitation. Action potential causes of opening and closing the ion channel. It started when voltage-gated sodium channel open allowing positively charged ions rush into the cell making the membrane depolarize. Membrane depolarization leads to the opening of high voltage activated calcium channel causing positively charged calcium ions enter the neuron which triggers the release of glutamate from the vesicle into the synaptic cleft. Then, glutamate will bind to two postsynaptic neurons: AMPA- permits the entry of sodium ions, then NMDA-permits the entry of calcium ions. All this influx of positive ions leads to depolarization and propagation of action potential. The next phase of AP is repolarization it causes of efflux of potassium ions into the cell through the opening of potassium channel, the membrane returns to resting membrane potential. The last phase is hyperpolarization, the potassium channel in this stage remains open until resting potential is met and returns to normal membrane potential.When there is too much glutamate around the neuron, it becomes hyperexcitable that results to seizure. Phenytoin and ethosuximide drugs lower the neuron excitability and enhance neural inhibition. The way, the drugs may prevent excessive firing of action potential in neurons by blocking the sodium and calcium channel thereby reducing the amount of sodium and calcium that enter into the neuron. When these two channels are blocked, there is no depolarization, no action potential, with that said no neurotransmitter being release and transmission of electrical impulses.Reference:Antiepileptics, acting predominantly as sodium-channel blockers.

Strayer University Week 5 Balance Work and Family Discussion
You have read about the unique challenges of those who need to balance work and family life including parenting. As a parent, student, or adult child, reflect on your own challenges and how you find balance. Use the Learning Resources to confirm or question your own experiences. From the readings describe at least one challenge you have successfully met including a specific strategy and one you are working on. In your paper identify how the resources reviewed provided some new ideas regarding how to balance all that you do.

a 500-750-word paper discussing various approaches to parenting based
on the information provided in the scenario. Address the following in

authoritarian, and permissive parenting styles, would manage the
behavior in the scenario. Discuss the effects of each parenting style on the child.Based
on Piaget’s theory, create a parenting plan to educate parents to react
appropriately to the scenario. Include the following in your parenting
plan:Discuss which parenting style is most effective in the long-term.How
can understanding the stages of child development improve a parent’s
ability to interact with his/her child? Provides an example using one of
Piaget’s stages.Include at least two scholarly references, in addition to the textbook, in your paper.Prepare
