Question
View this clip (http: //blt.ly/1Q0uzfE) from James Marsh's The Theory of Everything. After viewing the clip, answer the questions below. a. In this clip, we see that Stephen Hawking has only moderate control, strength, and dexterity in his fingers. He is able to move them, but he is not able to complete the task (i.e. placing the clothespin on the string). How could an individual with motor neuron disease be capable of slight movements without having full range of motion/control? b. Stephen Hawking's doctor says he will soon lose his ability to speak. Why would motor neuron disease affect an individual's ability to speak? c. How is paralysis resulting from motor neuron disease different than paralysis resulting from a motor vehicle accident? (Use sensory perception in your comparison.)Explanation / Answer
a. It is happening because the brain is not affected but only the sending and receiving of signals through neurons is progressively degrading and affecting the movement of voluntary muscles. The decaying process is just progressing gradually, its not complete. As the doctor said the life expectancy is two years. So, may be it will reach to complete decay in the time ahead.
b.It is because speech is also initiated as a response to an external stimulus. Speaking is a voluntary action that we do in response to certain thing that we see or feel the need to convey. Speaking also includes afferent and efferent neurons passing from the organs to the brain and then sending signals back from brain to the specific organ.
c. Paralysis resulting from motor neuron disease affects the voluntary muscles and neurons gradually, and progressively decaying the signal transmission mechanism. Whereas in paralysis caused by an accident, the spinal cord suffers more severe and sudden damage causing damage to the nerves and muscles.
