Norepinephrine

Introduction Illicit drug use is a prevalent issue in today’s society. According to the Australian Institute of Health and Welfare, the global increase of death and disease can be largely attributed to the illegal use of drugs (Illicit Use of Drugs, 2013). Though the rates of illegal drug use have remained constant in recent years, there has been a shift in the use of specific drugs (Illicit Use of Drugs, 2013). One drug that has received a lot of attention due to an apparent increase in usage is

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

When stress occurs, our bodies respond by releasing hormones that help our bodies deal with the stress. Catecholamines (epinephrine and norepinephrine) and cortisol are hormones that are major players in the stress response (McCance & Huether, 2010). Catecholamines share some common physiologic actions with cortisol. Catecholamines and its metabolic actions are similar to those of cortisol. Both catecholamines and cortisol cause an increase in blood glucose through increased gluconeogenesis

Females are less violent than males, at least according to recent research. Biologically speaking, there are differences in levels of violence in men and women (Wright, Tibbett, & Daigle, 2008). With eighty-five percent of arrestees being male, it’s easy to see that males commit many more violent crimes than females. These differences are credited to brain configuration, neurotransmitters, the limbic system, and hormones. There are different intellectual styles between males and females. These

deficiency of the neurotransmitter norepinephrine at receptor sites caused depression while increased levels of norepinephrine caused mania. Some evidence for Schildkraut’s account was established by the success rate of monoamine oxidase (MAO) inhibitor drugs, which block the reuptake of monoamines and facilitate the release of neurotransmitters such as norepinephrine and serotonin (8). Further evidence has been established by studies that found decreased norepinephrine levels in the cerebrospinal fluid

Your Body’s Response to Emergency How does the body prepare for emergencies? The answer lies in the Sympathetic Nervous System (SNS). It is the branch of the Autonomic Nervous System (ANS) that controls the body’s reaction to physical and emotional stressors. The sympathetic branch activates the glands and organs that defend the body against attack. It is called the fight-or-flight response. This is a primitive response designed to protect from danger. When danger is perceived, the sympathetic

Norepinephrine is a neurotransmitter released from noradrenergic neurons. It is one neurotransmitter responsible for the fight-or-flight response that activates the sympathetic nervous system. Strattera does not stimulate production of norepinephrine, rather it prevents reuptake of norepinephrine and allows the neurons to maintain the epinephrine that is already being produced. Strattera selectively blocks the norepinephrine reuptake transporter located on the

Coping with Anxiety. Nicorelys Rodriguez. PSY 100 / 1700. Prof. Beryl Duncan Wilson. Borough of Manhattan Community College. Coping with Anxiety Literature review In 2013, associate professor of psychology at the University of California, Kate Sweeny and her researchers surveyed 230 law school graduates for a period of four months after taking their bar exam in July 2013 ( J. Hoffman, 2015). The purpose of her research was to focus on the waiting period during which the person is

Question 1 a) DNA replication is the process, where a cell passes this DNA sequence onto other cells when it divides. It is known as mitosis as it must duplicate its genome so each new cell has a copy. This occurs during interphase. For the duration of DNA replication the enzyme DNA helicase are significant as they distinct double-stranded DNA into single strands letting each strand to be copied. DNA polymerase is another important enzyme that starts attaching new corresponding nucleotides to these

Abstract This paper will be exploring two main topics with the first being “sympathomimetics” which are drugs that produce physiological effects of the sympathetic nervous system by promoting the stimulation of the sympathetic nerves. We will be considering how the process of stimulation from sympathomimetic drugs occur and how they affect the sympathetic nervous system and what medications that can promote or inhibit a sympathomimetic response. The second topic being “anticholinergics” which are
