I don't have this textbook, but if it's possible to post the actual questions I may be able to help you somewhat. :hey: Title: When admitted to the emergency room, John was holding his right hand, which had a deep puncture hole Post by: bhsgurlz on Jun 9, 2011 Here are the Critical Thinking Questions:
#2: What specific process do anesthetics impair? How does this interfere with nerve transmission? #3: When admitted to the emergency room, John was holding his right hand, which had a deep puncture hole in its palm. He explained that he had fallen on a nail while exploring a barn. John was given an antitetanus shot to prevent neural complications. Tetanus bacteria fester in deep, dark wounds, but how do they travel in neural tissue? #4: Rochelle developed multiple sclerosis when she was 27. After eight years she had lost a good portion of her ability to control her skeletal muscles. Why did this happen? #5: In the Netherlands a young man named Jan was admitted to the emergency room. He and his friends had been to a rave. His friends say he started twitching and having muscle spasms which progressed until he was “stiff as a board.” On examination, staff found a marked increase in muscle tone and hyperreflexia involving facial and limb muscles. In his pocket, he had unmarked dark yellow tablets with dark flecks. Analysis of the tablets showed them to contain a mixture of ecstasy and strychnine. Ecstasy would not cause this clinical picture, but strychnine, which blocks glycine receptors, could. Explain how.

(2) They block neurotransmitters in the brain, thus blocking impulses out (i.e. muscle movement) and impulses in, sensation of pain. Thus, you are asleep, paralyzed and don't feel a thing. They block neurotransmitter release by altering the flow of sodium ion into neurons, and as I mention, this prevents nerve impulses from being generated, causing the brain to become unconcious.

Title: When admitted to the emergency room, John was holding his right hand, which had a deep puncture hole Post by: lewis on Jun 9, 2011 Quote Rochelle developed multiple sclerosis when she was 27. After eight years she had lost a good portion of her ability to control her skeletal muscles. Why did this happen? Multiple sclerosis affects the electrical signals that are send form the brain to different parts of the body.

Strychnine blocks glycine receptors in the spinal cord, leading to unregulated stimulation of muscles, and spastic contraction to the point where the muscles cannot relax.
