Norepinephrine

the potential causes contributing to Jennifer’s depression could be genetics. Her mother also experienced a form of depression as she would spend much time crying and binge drinking. She could also have low activity of the neurotransmitters norepinephrine and serotonin which have been linked to depression. The final reason could be that the activity in certain parts of the prefrontal cortex of her brain are low. The biological model would treat depression in a couple different ways. One is…

continued administration of fluids until this is deemed futile. Moreover, patients with hypotension unresponsive to the initial fluid challenge (i.e. septic shock) should receive additional cardiovascular support in the form of vasopressors (i.e. Norepinephrine as first choice vasopressor followed by Epinephrine) to maintain a MAP of 65mm Hg or…

alertness or hours of sleep with depressive symptoms. In the relationship between poor sleep quality and altered stress reactivity, daytime sleepiness and adrenocorticotropic hormone (ACTH) reactivity were associated, alertness complaints and norepinephrine (NEpi) reactivity were related, but there were no significant relationships between sleep complaints and cortisol, ACTH, or NEpi reactivity, excessive sleepiness and cortisol, ACTH, or NEpi reactivity, or hours of sleep to cortisol ACTH, or…

(Madras, 2013). Moreover, dopamine agonists, such as cocaine and amphetamines, typically increase positive symptoms (Madras, 2013). Researchers have implicated several other neurotransmitters in the etiology of schizophrenia, including serotonin, norepinephrine, GABA, glutamate, acetylcholine and nicotine (Sadock, Sadock, & Ruiz,…

Depression can occur due to of a combination of genes, brain chemistry and brain structure (Sutton, A. 2011). Research shows that changes in chemicals such as serotonin, norepinephrine and dopamine; which are the three main chemicals related to mood and motivation that carry messages within the brain, result in depression (Beyond Blue, 2014). By looking at pictures of the brain, scientists can also see that the structure of…

Attention Deficit Hyperactivity Disorder or better known as ADHD is a very common disease involving a person to be inattentive, hyperactive, and impulsive. People that deal with these symptoms does not mean they automatically have ADHD. People that get diagnosed most likely will experience these symptoms more frequently and it will negatively affect their everyday life. People dealing with this disease will generally miss small details, have trouble staying still, or being quiet. About 9% of…

Adderall, like most of the material substances of this world, was created with good intentions, but the nature of the human race has yet again defiled another effort to assist those in need. Adderall, regarded as a prominent drug in the treatment of ADHD, narcolepsy, and sometimes depression, has developed into what is now known as a ‘study-drug’, which has not only ravaged its way through college campuses damaging the mental and physical health of college students but also has created a black…

between the medulla and the heart joining the SA and AV nodes. Some sympathetic fibers terminate in the myocardium of the ventricles. The sympathetic nerves transmit their message to the muscle cells of the heart and arteries by the release of norepinephrine (NE), which increases both the heart rate and stroke volume. Sympathetic stimulation increases BP. (Winberg, 2014). 1.1.2 Parasympathetic nervous system - Parasympathetic fibers Heart activity may be altered by the cardiac center in the…

JACKSONS ZONES OF TISSUE INJURY Jackson’s Burn Wound Model provides a model for understanding the pathophysiology of a burn wound. Primary injury is the zone of coagulation nearest to the heat source . This zone has irreversible tissue necrosis at the centre of the burn due to exposure to heat, chemicals or electricity. The extent of the injury is dependent on the duration and the temperature of exposure . Zone of Ischaemia is the zone surrounding the central zone of necrosis in which there…
