There are three different theories that are used when talking about how we react to stress through the physiological aspect or the psychological aspect. The first is part of the physiological aspect of stress called the Cannon Fight or Flight theory which was proposed in 1914. Fight or Flight response is a physiological stress response that evolved to help organisms to survive immediate danger. The theory states that when an organism, human being or animal, faces imminent danger (acute stressor) the body arouses quickly and is ready to act via two different systems. They are the sympathetic nervous system and the endocrine system. The sympathetic nervous system stimulates the adrenal medulla which is part of the endocrine system and is the region that produces the hormones such as adrenaline and noradrenaline. These hormones increase heart rate, blood flow, and glucose levels to prepare the body for an emergency. This response from the body suggests that the body knows how to protect itself and reach homeostasis. These two systems work together to either fight against the danger or flight away from the danger. Lord, King and Pfister in 1976 studied the Fight or Flight response in animals through a very unethical study. They administered chemicals on male hooded Wistar rats which inhibited the neurotransmitters from functioning normally. This made it very difficult for the rats to escape an electric shock. The results of the study suggest that the Flight or Fight response

Thesis Statement: Through his early life experiences and with the knowledge he left behind, Sir Isaac Newton was able to develop calculus, natural forces, and optics. From birth to early childhood, Isaac Newton overcame many personal, social, and mental hardships. It is through these experiences that helped create him to be the person we know today, that is why he is worthy of the Scientist of the Century award.

In Prospero 's case in Masque of the Red Death Prince Prospero, was faced with the threat of survival, surviving the Red Death, a plague sweeping his kingdom killing all it comes into contact with. To produce the fight-or-flight response, the hypothalamus activates two systems: the sympathetic nervous system and the adrenal-cortical system. The sympathetic nervous system uses nerve pathways to initiate reactions in the body, and the adrenal-cortical system uses the bloodstream. The combined effects of these two systems are the fight-or-flight response.When the hypothalamus tells the sympathetic nervous system to kick into gear, the overall effect is that the body speeds up, tenses up and becomes generally very alert. If there 's a burglar at the door, you 're going to have to take action fast. The sympathetic nervous system sends out impulses to glands and smooth muscles and tells the adrenal medulla to release epinephrine and norepinephrine into the bloodstream. These "stress hormones" cause several changes in the body, including an increase in heart rate and blood pressure.At the same time, the hypothalamus releases corticotropin-releasing factor into the pituitary gland, activating the adrenal-cortical system. The pituitary gland secretes the hormone ACTH (adrenocorticotropic hormone). ACTH moves through the bloodstream and ultimately arrives at the adrenal cortex, where it activates the release of approximately thirty different

I interviewed Durward “Durk” Lynch he is in my field of interest where I want to work as one day. He is a Nurse Practitioner at the Vanden Bosh Clinic and at the College Clinic. He gave information on his background and what drove him to be a Nurse Practitioner (NP). He really has had a lot of experience, as I will explain to you what he has shared.

Adrenaline is hormone that is secreted by your adrenal

There are many symptoms associated with the physiological responses of the fight-or-flight including dilation of pupils, increased and more rapid heart rate, and acceleration in the respiratory system. The fight-or-flight response is a very important and crucial response both mentally and physically that is a building block for the human body. Without it, humans may not be as adapted to the dangerous and stressful environment we call our world. Finally, to summarize the steps of the fight-or-flight response. First, a threat or stimuli are perceived by the retina and signals are sent to the brain. Next, the brain processes the signals and determines whether the threat is real. Then, the adrenal medulla is sent synapses from the cerebrum and secretes a liquid with high levels of adrenaline called epinephrine. After that, the secreted adrenaline is mixed with glucose. Next, the adrenaline and glucose are rushed throughout the bloodstream and to the muscles. The muscles then tense up and are given an extra boost of strength and speed. Lastly, the muscles are used to either fight or

Paul Keating’s speech ‘funeral service of the unknown Australian soldier’ and Noel Pearson’s speech ‘an Australian history for us all’ have developed and expressed ideas using language appropriate to their audience, purpose and form. Despite the fact, it is fundamentally the speaker’s skills in the construction of the speech that determine its decisive success.

The adrenal gland is the endocrine gland that is activated when one is surprised or experience fear. This adrenal gland is located at the top of the kidneys. The fear hormones known as epinephrine circulates through the bloodstream to all cells of your body ("Fear: Body Alert!" 2013). The effects of adrenaline which is also called epinephrine is similar to the effects of the sympathetic nerve action. These glands increase blood flow to the brain and muscles in defense of the flight or fight response (Griggs, 2014, p.

Lyndon Johnson was convinced that liberal nationalism and the power of the federal government could transform society. His faith grew out of his youthful experiences with poverty in Texas, his political apprenticeship during the New Deal, and his desire to surpass Roosevelt's legacy. When he took office in November 1963, after John F. Kennedy's death, Johnson inherited the early initiatives to address poverty that the Kennedy administration had under consideration. With characteristic enthusiasm and expansiveness, Johnson declared a war on poverty in 1964 and pushed legislation through Congress to establish the Office of Economic Opportunity (OEO).In this speech, the purpose Lyndon B. Johnson outlines his vision and goals for "The Great

According to Merriam-Webster dictionary, adrenaline is defined as “a substance that is released in the body of a person who is feeling a strong emotion (such as excitement, fear, or anger) and that causes the heart to beat faster

It works by the hypothalamus producing corticotrophin-releasing-hormone that. stimulates the pituitary gland to release adrenal-corticortrophic hormone. The adrenal-corticortrophic hormone alerts the adrenal glands to produce corticosterioid and glucocorticoids then it restarts. Also when the threat passes, cortisol levels fall and the parasympathetic nervous system dampens the stress response (Understanding the stress

The fight or flight response is a complex response that affects a great deal of the body. Initially, a signal travels to the brain, to which the amygdala responds. The amygdala sends a nerve impulse to the hypothalamus, which sends a chemical signal to the pituitary gland. The pituitary gland then releases a hormone that travels to the adrenal gland, along with the nerve impulse from the hypothalamus. Within the adrenal gland, the impulse initiates the release of epinephrine and adrenaline, which affect various cell types. Inside the adrenal gland, the adrenal cells are affected by the presence of the hormone and activate the G protein complex. This complex stimulates adenylate cyclase, which converts ATP into cAMP. cAMP activates the protein Kinase A, or PKA, which releases catalytic subunits. These subunits travel to the mitochondrial membrane and activate the steroidogenic acute regulatory protein. This protein mediates importing cholesterol into the mitochondria, which uses enzymes to convert the cholesterol into 17-OH-pregnenolone. The pregnenolone is then released to the endoplasmic reticulum,

Whenever I think of our speech captains, I think of individuals who are responsible, respected, and kind to those around them. I view them as people who others can look up to, go to for help, and overall be a friend to someone who needs one. I know that when I joined the team, I was quite content with the captains that were in place, but I feel like there could always be more within these positions. To me, being a captain means being a role model and significant figure in the eyes of new members or even those just looking to become involved in the activity. When I think of the reasons why I should be a speech captain, it’s to be able for others to see me as I see our captains now. I want to be a leader who inspires others to not only be hardworking

The best way to prepare for a presentation, one must consider the best method, the type of presentation and the audience for a given topic. There are four different types of presentation methods they are; Impromptu, Extemporaneous Speaking, Using a Manuscript, and Memorization. Each of the four methods is appropriate in certain situations. Impromptu is a speech that frequently involves no preparation time and forces you to think on your feet. With no opportunity to prepare, you must rely on what you know. Extemporaneous is a speech that involves preparation and practice. This form of delivery has many advantages.
