Fear is a survival mechanism. Our brains are able to detect when there is a source of stress that might be a threat, it then activates a series of events that enable us to be ready to fight or escape. This reaction is scientifically known as “fight or flight.” When stress activates that part of the brain, known as amygdala region, it overrides conscious thought which allows the brain to contribute all of its energy into facing the threat.

Anxiety, it’s part of every day life. It is a feeling of fear that interfears with our daily activity brought on by traumatic events. The feeling of being worried, fearful, or apprehensive. Even though some level of anxiety is part of everyday life but when it starts to control your life, that’s when things really get out of hand. What causes anxiety? Maybe a big test or a job interview, but that’s normal. What’s not normal is if you’re worrying that if you breath in air, your lungs will burn and shrivel up. That is what is referred to as Acute Stress.

Anxiety is the body’s biological and psychological response to stressors. A stressor can be anything that cause an individual to feel threatened or cause stress. The body decides whether or not a situation is too difficult to deal with alone based upon past experiences and what it sees and hears. When a stressor is detected, the body’s stress response system known as the hypothalamic-pituitary-adrenal axis (HPA axis), begins a surge of biological events. As a result, the stress hormones adrenaline and cortisol are released. In the brain, the hypothalamus will then send a chemical message to the pituitary gland. However, people can

Anxiety is the body’s natural reaction to stress. It allows a person to prepare for an event that could be harmful. Anxiety stems from the amygdala, a section in the brain that is in charge of emotions and our natural "fight-or-flight" response. As these signals spread throughout the body, the nervous system causes the heart to begin to pump more blood and tense up the muscles. Anxiety has both a physical and psychological effect on humans. The effects that stress and anxiety have on the body can be incredibly dangerous if it is not treated properly

The interpretation of stress is believed to occur in the cerebral cortex of the brain based upon sensory and other input (such as from chemo-receptors). The two categories of stress act through somewhat different neurological mechanisms, but the general features are similar. Cognitive processes are involved in the assessment of the input for both categories as to whether the input represents a potential threat in a routine manner. The amygdala appears to have a central role in the stress response [46, 47]. Amygdala neurons release corticotropin-releasing hormone (CRH) which has two major effects: it causes the brain stem (including the rostral ventrolateral medulla) to stimulate the sympathetic nervous system (SNS) through spinal nerves, and

Scovel (1978) defined anxiety as “apprehension, a vague fear that is only indirectly associated with an object” (p.134). According to Scovel’s definition, anxiety is an inexplicable inner feeling that someone have toward somebody or something which constitute a condition of breakdown in actions. Darwin (1872) defined anxiety as a person’s internal feeling which are triggered whenever physical risks or danger exists. In his definition, the feeling of distress or discomfort exists when a physical harm occurs and thereby intellectual threats are rolled out of the equation. Beck et al (1985) stated that the inner feeling would launch a reaction toward the fears of something or somebody in his or her environment. May (1977) viewed anxiety as “an

Anxiety disorders are conditions of persons who develop intense fear and anxiety for real or imagined reasons. Since the last century, it has been classified under the science of psychiatry when it was observed that fear and apprehension could affect the mental and physical functions of those afflicted. It is manifested in various symptoms classified into mental anxiety, physical tension and panic attacks. In many instances, the anxiety persists continuously even if the perceived threat or feared object is no longer present.

This article is talking about how we deal with anxiety. The author used an example as the start of this article. The studies conducted by researchers provide the information that the people with different levels of amygdala activity have different ways to deal with or control their anxiety feeling. Also, at the end of this passage, author gives us several suggestions that may help us to control the feelings, understand and acknowledge our feelings and where they come from; take a deep breath and release the physical sensations; make a detailed schedule for the thing that we want to control with.

It is natural for a person to have a sense of stress and worry throughout the their daily experiences. Whether it has to do with work, school or finances. Surprisingly it is also natural for some people to experience fear, nervousness, and anxiousness out of nowhere. People may think it is abnormal to have a rush of emotions out of the blue, but this is something a lot of people in society have to deal with on a daily basis. The combination of these emotion reflexes is what is known as anxiety. Anxiety is a mental disorder that makes a person have sudden unwanted feelings of fear, anxiousness, and worrisome. Having an anxiety episode is something the can frequently occur and take a troll on a person’s mental and physical health. Anxiety is

People will sometimes feel a general state of worry or fear before being faced with something challenging, and this reaction to a difficult situation is called anxiety. Anxiety is defined as a general term for several disorders that cause nervousness, fear, apprehension, and worrying. Anxiousness is considered a normal thing that everyone will experience from time to time, but when anxiety interferes with a person’s sleep or ability to function, it is a problem.

The biological roots of post-traumatic stress disorder also partly lie in serotonin. Serotonin is a neurotransmitter involved in such functions as hunger, aggression, sleep, and fear response. The neurons that produce serotonin have raphe nuclei in the brain stem and extend to other parts of the central nervous system, including the amygdala, a small, almond-shaped portion of the brain that controls fear response. Anxiety results in lower levels of serotonin (5), and these lower serotonin levels may act on the amygdala in some way to help produce the symptoms of post-traumatic stress disorder. The National Institute of Mental Health and the Anxiety Disorders Association of America co-sponsored a recent conference at which researchers declared that "circuits involving the central nucleus of the amygdala appear to process conditioned fear responses to specific stimuli, while circuits involving a closely related area, the bed nucleus of the stria terminalis, handle non-cue-specific, non-conditioned anxiety. Both circuits, in turn, connect to the hypothalamus , brainstem, and other brain areas mediating specific signs of fear and anxiety." However, further research on the amygdala's specific role

Psychological disorder on anxiety. Anxiety is a universal human experience and is a human emotion. It can be defined as a feeling of apprehension, uneasiness, uncertainty, or dread resulting from a real or perceived threat. Anxiety is a vague sense of dread related to an unspecified or unknown danger. Most people’s anxiety is caused by fear. Fear is a reaction to a specific danger and can cause anxiety in a person. Anxiety affects everyone at a deeper level. It invades the central core of the personality and erodes feelings of self-esteem and personal worth. Anxiety can cause physical symptoms. Some symptoms are shakiness, raped heart rate, and increased respirations to name a few.

One of the next major questions that psychologists should attempt to answer was proposed in Sharp et al. (2015) in which the authors of the paper discussed the transdiagnostic dimensions of anxiety, particularly the neural mechanisms and executive functions involved. The two dimensions of anxiety that the paper specifically focused on were anxious apprehension and anxious arousal. According to the paper, these two factors have helped to bridge the gap between psychological and neurobiological models of anxiety. The study of neuroscience, which is in its relative infancy, has also led to many changes in our understanding of psychological diagnosis and disorders. This new field, however, has also resulted in many unanswered questions. These questions are numerous and varying and include researchers’ attempts to identify the specific mechanisms through which disorders occur, genes that may predispose individuals to certain disorders, new methods of measuring the constructs that make up “disorders”, and ways of effectively treating these disorders.

Anxiety is an emotion characterized by an unpleasant state of mind, often accompanied by nervous behavior and a series of unpleasant feelings and a symptom of underlying health problems. “Anxiety is not the same as fear, which fear is a response to an immediate threat, whereas anxiety is the expectation of a future threat”. Anxiety is distinguished from fear, which is an appropriate emotional response to a perceived threat and is related to the specific behaviors of fight-or-flight responses, defensive behavior or escape. These behaviors occur in situations only perceived as uncontrollable or unavoidable. The behavior shown by someone who is suffering from anxiety goes into different categories (Barry 146).

Fundamentally, anxiety is a natural response to stress or difficult situations. The human body initiates anxiety reactions to help heighten senses, speed reaction time, and try to anticipate possible outcomes in intense situations. The downside is that when these responses become uncontrolled or involuntary,
