Sympathetic nervous system

deficiency in the amount of oxygen reaching the tissue and hypercapnia, excessive carbon dioxide in the bloodstream. Chemoreflex is a powerful stimulus that can “excite” the sympathetic nervous system, this excitement can then evoke “elevations in the muscle sympathetic nerve activity (MSNA)”. The interaction between chemoreflex and sympathetic responses has been studied by researchers for years because it is believed that chemoreflex activation leads to elevations in muscle synaptic nerve…

According to Michael Richardson, a music therapist, music therapy is “the use of music to achieve other than musical goals” (“Music Therapy” 0:08-0:12). Imagine the agony that terminally-ill patients endure close to their final days. Pain becomes unbearable despite the constant intake of narcotics, since these drugs only suppress pain for a limited period of time. Even though pain can be “well controlled” with medicine, some sufferers personally decide to cease treatment (“What Happens”). Yet,…

You’re hiking through the woods when all of a sudden you hear a stick crack. You look cautiously around for the hazard, but you see no one. Your heart starts racing. You begin to sweat. Your mouth dries and you feel butterflies in your stomach. Your hair stands on end. You feel a surge of energy and in a split second you find yourself running away from the noise. Whether you’re aware of it or not, your body just went through a response known as the fight or flight response also known as the…

Methamphetamine is a stimulant that affects the Central Nervous System and targets the sympathetic system. Meth can be administered by intranasal or oral use, intravenously, and can also be smoked. Depending on the route of administration the time it takes to affect the body will vary. Eventually the drug gets distributed to the rest of the body via the bloodstream. This stimulant, when abused, can wreak havoc on the brain and body because it increases the synaptic levels of dopamine, serotonin…

The autonomic nervous system is apart of the nervous system that receives instructions from the brain. It has two parts which are the sympathetic and parasympathetic. The sympathetic nervous system controls the bodes response to a perceived threat and is responsible for the fight, flight or freeze response. Where as the parasympathetic nervous system function is to control the homeostasis and the bodies rest and digest response. The sympathetic nervous system has a thoraco-lumbar outflow from…

Synopsis According to Wheeler (2014), “Post traumatic stressed disorder (PTSD) in adults is characterized by persistent re-experiencing a highly traumatic event that involves actual or threatened death or serious injury to self or others, to which the individual responded with intense fear, helplessness, or horror.” Events or situations that are considered traumatic are natural disasters, military combat, prisoner of war, a plane accident, bombings, assault, rape, abuse, or the a diagnosis of a…

Therefore, the brain and the entire nervous system are crucial in providing information on disease symptoms to physicians and thus assist in diagnosis. This paper aims to discuss the composition of the neuroanatomy and its importance in the diagnosis of diseases. Neuroanatomy involves the study of body anatomy and how the nervous system is organized. The nervous system differs depending on the animal’s symmetry and as such vertebrates have a segregated nervous system consisting of the internal…

stressor. The mind sends signals to the endocrine, nervous, and immune systems to tell them to react in a way that is proper for the specific stressing situation. Stress response behaviors include increased awareness and cognition, a sense of euphoria and enhanced analgesia, also known as the inability to feel pain (Smith & Vale, 2006). The HPA axis and stress have several factors they share, as they…

is a discipline, it makes very important contribution to the nervous system. I will be briefly going over biological bases of behavior and the mental processes. The first thing I will be talking about is endorphins. The second thing I will be talking about is the sympathetic nervous system, and the parasympathetic nervous system. The first thing I’m going to talk about is endorphins. Endorphins are produced by the central nervous system. Endorphins act like a morphine, or heroin, they are…

Stressed lifestyle and personality are some of the psychological factors that influence health and behaviour in our lives. However, our response to stressors determines our ability to control and manage or develop illness out of the stress. “Stress is experienced when a person’s perceived environmental, social, and physical demands exceed their perceived ability to cope, particularly when these demands are seen as endangering the person’s well-being in some way” (Cardwell & Flanagan, 2012).…
