STUDY QUESTIONS

1. The smallest voltage required to produce a contraction was .85. The proportion of fibres in the muscle that were contracting was only 10-20% of total fibres available. The nervous systems controls the amount of muscle fibres that contract. In this case only a small depolarization is causes and this was evident in the graph produced
4) The all or none law states that strength of muscle force will be the same at any stimuli strength if the stimuli strength is above the threshold of the muscle in question. The muscle will either respond fully or not respond at all, hence the name all or none. Once the minimum force threshold is met the muscle will respond, however below the minimum threshold no response will be visible. The muscle contraction is all based on the ability of channels to open. The more the channels open the stronger the depolarization event occurs. Responses to stimuli were graded on the strength of the contractions and the ability to create force. These forces were able to be compared to other forces throughout the experiments.

EFFECTS OF STRETCH ON CONTRATION FORCE

1. The effect of stretching the muscle increases the contraction strength to a certain point until the muscle is over stretched. This was where our results stopped. This is known as the optimal length. However if we kept stretching the muscle over time it would of plateaued before decreasing. The muscle stretches to achieve an optimal length. If a muscle has not reached its optimal length less tension can be developed for 3 reasons: The thin filaments of one side of the sarcomere become overlapped with the other which does not allow actin to bind to a large portion of the filaments limiting the action potential. The thick filaments become forced against a Z section and further shortening is caused. The shorter the muscle becomes less and less actin is able

Research Paper On Breaking Social Norms

...stranger, what do you usually say or do? Do you give them a kiss on the cheek, high five, or do you give them a hug? In our society, when we meet a complete stranger we tend to either just say “ hello”, exchange names, and a quick handshake.

Tenerife & Everit Case

...lead individuals of the expedition, Rob Hall and Scott Fischer were very confident in their ability to bring their clients to the summit. During this adventure, early on, there were obvious issues and signs, such as health issues amongst clients, warning signs of possible bad weather conditions during hike to summit, which they ignored. Moreover, these signs and interruptions lead everyone to believe that there was a possibility, that they would not make a safe return during their descend from the summit. My main concern about this venture was how they both were responsible for everyone getting on top of the summit and failed at taking heed to the warning signs at based camp. Although Hall and Fischer hired all types of individuals they still needed to find out to make sure that everyone that was on this venture was capable to go up to the summit and in good health. In the end both Hall and Fisher lost their lives helping others and still left their clients to survive on their own. Clients that were upon this expedition had concerns but his only concern that he would possibly have to save somebody else during his hike to the summit. They both lost their lives doing just that. Hall clients arrived at base camp with respiratory and digestive ailments while Fisher had logistical problems. Normally when you have issues like this from the start it’s would have been a clear indication to make a decision to refuse people to go to the summit and revisit their plan about going...

John wrote in Chapter 20:31 “31 But these are written that you may believe[a] that Jesus is the Messiah, the Son of God, and that by believing you may have life in his name.” These events offered proof of Jesus divinity according to Dr. Elmer Towns author of The Gospel of John, Believe and Live.

...the video and who came up with the idea of using sign language? Was it input from Sia or was it your visual response to the lyrics? It was Sia's idea to incorporate sign language in the video -I was told she would like to include it in some way when I received the song to write the treatment. I loved the idea of doing the entire video in sign language instead of lip synching the vocals. A music video is a visualization of the song, and the sign language is an interpretation of the song into a visual language, so it's a perfect fit. What was the purpose behind using so many different kinds of light sources and the shadows they create? I wanted to explore different aspects of sign language. In the first section where Sia is performing under regular lights, the sign language is treated in its linguistic form as a method of communication, and the focus is on the performative aspect of the ASL (American Sign Language) interpretation. The shadow section is kind of a creative expansion on the relationship between signs and their meaning. The shadows of the hands directly transform into things themselves, and create an imaginary world around Sia. Where the shadow section is more two-dimensional, the UV section is four-dimensional and plays with the shapes of the signs in time and space (particularly with the trailing effect) and the extension of the signs as expressive gestures into the realm of dance. How difficult was it filming in UV lighting? Actually setting up the lights for the UV...

Heart Disease

...Running head: HEART DISEASE Heart Disease Victoria Martin Grand Canyon University: NRS-427V-0500 October 3, 2015 Heart Disease Heart Disease is a big term used to describe a lot of heart conditions but the most common type in the United States is known as coronary artery disease. This is where the flow of blood through the heart is slowed down due to plaque buildup in the arteries within the heart which blocks the blood flow and can lead to a heart attack. In the United States about one in every three adults or seventy million people has high blood pressure. Only about half of these have this under control by either diet and exercise or medication. Blood Pressure is a very common condition but if not under control it increases the patients risk for heart disease and stroke significantly. High blood pressure is known as the silent killer as it has no warning signs or symptoms so often patients do not even know that they have it and this is very dangerous (CDC, 2015). In the United States and most other societies, there is a strong tendency for Blood Pressure to rise progressively with increasing age; however, epidemiologic studies indicate that age-related increases in BP and the occurrence of hypertension are uncommon in societies whose members live in isolated settings. These findings indicate that high BP is not an inevitable consequence of aging and that prevention of hypertension is a realistic goal (Epidemiology and the Prevention of Hypertension. (n.d.). ...

Focus on the change of your attitude and opinion: How and why it occurred. TraumaOne: As Life Flashes Through Your Head Has there ever been a time when today was the last time a love one or friend would be alive? Not to bring back any bad memories of the past, but the thought of what actions have to be completed to ensure that this particular time by this road on a summer day is not going to be that day. Just a typical afternoon working at the new salon and the owner comes and says “Can you two guys go put up this sign up by the road?” Let us take an imaginary trip through your head of the first three hours after the accident takes place from putting up the sign, to the accident when the life of a friend flashes through your head and finally finding out that the friend is going to recover completely after some time in the hospital. The afternoon was just as any ordinary afternoon of work that gets a new hair salon business up and running. It began with getting supplies together to go clean the marquee before putting the new sign up so that everyone would know that the hair salon that used to be beside Wal-Mart in our town had not gone out of business, just a change of location. Once the supplies were gathered, we headed to the marquee which was located by...

Cultaral Comparison of Deaf Culture and Hearing Culture in the Usa

... | |Nathaneil Godfrey | | | PDI Power Distance Indicator Power distance This dimension deals with the fact that all individuals in societies are not equal – it expresses the attitude of the culture towards these inequalities amongst us.  Power distance is defined as the extent to which the less powerful members of institutions and organisations within a country expect and accept that power is distributed unequally. It has to do with the fact that a society’s inequality is endorsed by the followers as much as by the leaders. http://geert-hofstede.com/ Deaf culture I think Deaf culture would score at the low end on this. In the Deaf community we believe strongly in equality. We are not like any other culture because we are made up of so many different backgrounds, races, and religious groups. But we have a common goal and that is to come together as one and function smoothly. Yes, we have our leaders such as I.Jordan King, our first Deaf President at Gallaudet University...

Love Contracts

...time, through many studies, it has become a known fact that America is one of the most work-oriented nations in the world. Americans have a reputation for spending more time at work than we do at home. With that in mind, why is finding love in the workplace considered something that would not, could not, and should not be done? According to a study published in the L.A. Times (2007), 43 percent of Americans admit to dating someone from their place of employment. There used to be a time when dating at work was considered taboo and was even forbidden by many companies. Presently, more companies are beginning to view the subject differently and allowing dating inside the companies under certain guidelines. The most common guideline these companies employ is known as a, Consensual Relationship Agreement which is also known as a love contract or a CRA. A CRA ensures that both parties have entered into a relationship voluntarily and consensually. WHY USE CONSENUAL RELATIONSHIP AGREEMENTS Consensual Relationship Agreements are beneficial for almost any work environment. According to the L.A. Times, (2007)Consensual Relationship Agreements are a type of contracts that shield employers from liability if intimacy later congeals into a sexual harassment lawsuit or some other type of discord. Up to today’s date, CRAs have not been used in court but one could look at the Myers v Trendwest Resorts case where the plaintiff claimed her supervisor repeatedly made unwanted sexual advances...

Yom Kippur

...gray-haired woman was crying her eyes out. She had just been fined $100 by the judge because a month ago her dog made a mess on the front lawn of the courthouse. “I just got out of the cab and I leashed Poopsie to the light pole. After I paid the fare and gave the driver a dollar tip, I turned around and saw that Poopsie had made a mess. I didn’t have any plastic bags, so I said, ‘Well, Poopsie, let’s go home. There’s nothing I can do about this now.’ “We were just starting home when I heard this voice out of nowhere: ‘Excuse me, ma’am. Is that your dog?’ I turned around. It was an officer of the law. Well, of course, it was my dog. ‘That dog just made an illegal deposit on the courthouse lawn. As its owner, it’s your responsibility to dispose of that deposit. See the sign over there? I’m going to have to write you a citation.’ “I asked him what sign he was talking about. He pointed all the way down to the end of the block. One little sign, a block away! How could anyone see that? I couldn’t see that sign with my best opera glasses. The officer said that I could fight the ticket. He said the judge was a nice old man who owned four dogs. So I said, ‘OK, thank you, I’ll fight the ticket.’ “So when I went to court, I dressed Poopsie up in his prettiest ribbons and made extra sure he did his business first. We were both so excited.
