You get a phone call that changes your life: your child or a relative's child has in a car accident. He has been taken to the hospital, but is unable to move his legs. Many times, having as much knowledge as possible on a medical topic better prepared you to talk to medical professionals. This is we will dig deeper into learning about our body systems. this discussion i will explore spinal cord injuries and their prognoses. You will need to conduct research and document evidence.

1. Describe the process of nerve healing in peripheral nerves and the difference between central and peripheral nerves.
2. Explain how the nervous system grows with us and how that supports it's function.
3. Suggest a reason why most neurons are amitotic.
4. Explain why neurons very rarely become cancerous.
5. Express how the symptoms mentioned in the letter demonstrate the connection between anatomy and physiology, based on injury location.
6. Provide insight into new research, perhaps with stem cells, and describe why specific new research may , or may not , be the answer to cure these injuries.
7. Discuss why medical professional should never guarantee an outcome with a nervous tissue injury.

Expert Solution

1- After injury axon of peripheral nerves can undergoes regeneration due to wallerian degeneration after disconnecting from cell body , this helps in fragmentation of axon. The main difference between central nervous system and peripheral nervous system is that CNS includes Brain and spinal cord whereas PNS includes all the nerves which branches out from CNS and connect other organs.

2 - Growth of nervous system starts with the formation or growth of dendrites and axons towards the target cells which further forms synaptic junction with the target cells. The syanpis and growth of nerves helps in proper transmission of information from Brain to target cells for control.

3 - Most of neurons are amitotic as these can not divide by mitosis due to the differentiation and absence of required organelles.

4 - As neurons are amitotic due to the absence of required organelles and division factors hence the chance of cancer is also low for neurons.

5 - According to symptoms given there is loss or degeneration of connection between PNS and target cells or organs. Here the change in physiology due to inactivity of organs in degeneration of nerves also leads to change of damage in anatomical structures.

6- Neural stem cell therapy can be used for damage of peripheral nervous system as stem cell can be transformed into nerves, oligodendrocytes, astrocytes and even schwann cells which can help in regeneration of nerves.

7 - Doctors can not give guarantee for complete treatment of such conditions as neurons are amitotic and complete regeneration is not possible even by stem cell therapy.

You and your team get a distress call from another ship indicating that there has been an explosion and their propulsion and navigation systems are now off line. A large piece of their ship has been jettisoned into space, and their life support systems are failing. They need help as soon as possible. You try to track them, but are only able to pick up the piece of the craft that had been projected away from them in the explosion....

You receive a phone call from your scientist friend. She is studying a new species of bacteria and has recently sequenced the genome of all individuals in her population. She started out with a genetically homogenous population but has just discovered a new mutation. She wants you to predict what the fate of the mutation will be in the population (fixed, lost or maintained as a polymorphism). A) If you are a strict neutralist (neutral theory all the way!!), what...

Suppose you just received a phone call about your dream job, and the company would like to invite you to an interview. Conduct initial research about the company and determine: What types of things you want to know about the company and/or the job? What do you want the company to know about you? What types of questions would you like to ask the company, and why? What types of questions do you hope the company asks you, and why?...

A phone call to the service center has a normal distribution with mean 10 min and standard deviation 2 min. During one day there were 5 phone calls and during the other day there were 6 calls. What is the probability that the sample average taken on each of the two days is at most 11?

Mr. Jones is waiting to make a phone call from a public phone at a train station. There are two public telephone booths next to each other, occupied by two persons, say A and B. If the duration of each phone call is an exponential random variable with λ = 1/6, what is the probability that among Mr. Jones, A, and B, Mr. Jones will not be the last to finish his call

During your visit to the doctor you learn that your child has a rare disorder. The prognosis is not good. But there are two possibilities for treatment: 1) cloning your child which will give a 100% new start or 2) starting your child on an experimental drug that has significant side effects and has not shown much efficacy for recovery. Do the research on a rare disorder in children with either of the two possible treatment and cite the source

You (or your child) have come to the conclusion that your moral and/or religious identity has changed in many ways since you were a child. Describe the changes: how they conflict (or not) with those of your parents; perhaps you have matured according to Fowler's stages of faith; perhaps you identify with two or more of Haidt's clusters of moral values; perhaps your gender has contributed to your moral development
