1. With good detail, describe the signal transmission across a neuromuscular (myoneural) junction that allows the nervous system to move the muscles of a football player. (Hint: See the videos on lesson pages 3-4.)

Waves of chemical and electrical charges are what will give an athlete an action. Furthermore, these charges will move along the neuron and the nerve impulses. The electrical charges the cell membrane reverses and charges at a high speed.

2. What environmental and behavioral factors led to Joseph's dehydration?

The environmental and behavioral that could have been factored into Joseph’s dehydration is that it is August in Florida, one of the hottest places to be in the summer time. The hot and dry weather will have caused overheating in Joseph’s body as well as the loss of water from sweating and playing in a strenuous three-hour game of football. Because Joseph did not rehydrate, Joseph experienced the symptoms of dehydration, muscle pain and cramping all symptoms of heat illness. …show more content…
Now that you know how a nerve impulse transmits through a neuron and into muscle tissue, explain why dehydration caused Joseph's muscle cramping? (Hint: During dehydration, a large amount of sodium is lost.)

Joseph’s dehydration caused muscle cramping because the lack of sodium from sweating with no rehydration caused the sodium gate way to open unproperly and the imbalance occurred. With the gateways opening at different times, causing Joseph’s cramping. When the opening of the potassium and sodium gateway opened, this will cause a brief bonding in the motor end plate. As these two gateways open at the same duration the end plate potential will become present. Next, the adjoining muscle regions are stimulated to create an action potential instead of creating an action potential.

4. How did caffeine contribute to Joseph's muscle cramping? (Hint: See the video on lesson pages

Life of Pi

...Acclaim for Yann Martel's Life of Pi "Life of Pi is not just a readable and engaging novel, it's a finely twisted length of yarn— yarn implying a far-fetched story you can't quite swallow whole, but can't dismiss outright. Life of Pi is in this tradition—a story of uncertain veracity, made credible by the art of the yarn-spinner. Like its noteworthy ancestors, among which I take to be Robinson Crusoe, Gulliver's Travels, the Ancient Mariner, Moby Dick and Pincher Martin, it's a tale of disaster at sea coupled with miraculous survival—a boys' adventure for grownups." —Margaret Atwood, The Sunday Times (London) "A fabulous romp through an imagination by turns ecstatic, cunning, despairing and resilient, this novel is an impressive achievement. . . . Martel displays the clever voice and tremendous storytelling skills of an emerging master." —Publisher's Weekly (starred review) "[Life of Pi] has a buoyant, exotic, insistence reminiscent of Edgar Allen Poe's most Gothic fiction. . . . Oddities abound and the storytelling is first-rate. Yann Martel has written a novel full of grisly reality, outlandish plot, inventive setting and thought-provoking questions about the value and purpose of fiction." —The Edmonton journal "Martel's ceaselessly clever writing . . . [and] artful, occasionally hilarious, internal dialogue . . . make a fine argument for the divinity of good art." —The Gazette "Astounding and beautiful. . . . The book is a pleasure not only for the subtleties of its philosophy...

Hia Its Ya Birthdya

...Yann Martel: Life of Pi life of pi A NOVEL author's note This book was born as I was hungry. Let me explain. In the spring of 1996, my second book, a novel, came out in Canada. It didn't fare well. Reviewers were puzzled, or damned it with faint praise. Then readers ignored it. Despite my best efforts at playing the clown or the trapeze artist, the media circus made no difference. The book did not move. Books lined the shelves of bookstores like kids standing in a row to play baseball or soccer, and mine was the gangly, unathletic kid that no one wanted on their team. It vanished quickly and quietly. The fiasco did not affect me too much. I had already moved on to another story, a novel set in Portugal in 1939. Only I was feeling restless. And I had a little money. So I flew to Bombay. This is not so illogical if you realize three things: that a stint in India will beat the restlessness out of any living creature; that a little money can go a long way there; and that a novel set in Portugal in 1939 may have very little to do with Portugal in 1939. I had been to India before, in the north, for five months. On that first trip I had come to the subcontinent completely unprepared. Actually, I had a preparation of one word. When I told a friend who knew the country well of my travel plans, he said casually, "They speak a funny English in India. They like words like bamboozle." I remembered his words as my plane started its descent towards Delhi, so the word bamboozle ...
