Effects of stress on Kidneys and Resistance phase of GAS
Biology
Stress is an emotional or physical strain normally caused as a result to the tension or pressure from the outside world. Some of the most prominent reactions to stress include tension, agitation, increased heart beat and lack of concentration. Although, it is inevitable to lead a life without stress still there are ways in which this situation can be controlled. (Health Information Publications 2002-11). This research essay aims to delineate the affects of stress on the renal system. It seeks to explain the physiological activities of the kidney under normal homeostatic conditions, and what may occur in the kidneys when the body is experiencing the resistance phase of the general adaptive syndrome
STRESS AND THE GAS
A human brain works in mysterious ways. It can regulate functions throughout the body, without you even realizing how far reaching these effects could be. This could sometimes result in increased heart beat, activated sweat glands regardless of changes in temperature, secretion of hormones from your pancreas or even building up of enzymes in your liver.
According to Tortora and Derrickson (2009) your brain can regulate functions throughout your body and it is quite surprising how far reaching those effects can be. It simply tells you what to do by simply sending a message through the nerves branching out from it down your spine to the various parts of your body.
Stress and the Autonomic nervous system
The automatic nervous system includes a set of nerves projecting actions that are either voluntary (automatic) and relatively involuntary. Our nervous system has two sides to it; the voluntary and the involuntary nervous system. The voluntary part of our nervous system is the conscious state of mind and the one behind our everyday routine. Whether you decide to pay your bills, move a muscle or even wave a hi-five to a friend.
"The two mutually exclusive activities perform quite different tasks from one another. On one hand the sympathetic nerves kick into action during the four F's of behavior -- flight, fright, fight and sex. These tend to originate in the brain, crossing your spine and branches out to all the organs, vessels and sweat glands. These nerves kick into action during emergencies and help you mediate vigilance, arousal, activation and mobilization. Hence as a result of your sympathetic nerve endings in your adrenal glands located above your kidneys, Epinephrine is secreted.
The parasympathetic nervous system on the other contrary, mediates calm and vegetative activities promoting growth, energy, storage and other optimistic processes. This usually engages in tasks such as slowing your heart beat, diverting the blood flow from your muscles back to your heart etc." Tortora and Derrickson (2009, pp. 22-23)
Effects of Hormones on Stress:
Stress can also be a major contributor towards activating the hypothalamus-pituitary peripheral glands. These in turn release an array of epinephrine and the non-epinephrine harmones into the hypothalamus-pituitary circulatory system and get the ball rolling. The epinephrine acts swiftly and within a course of minutes release another principal hormone called the CRH (Corticotropin releasing hormone) which eventually triggers the ACTH into the blood stream. Eventually, upon reaching the adrenal gland, they secrete the glucocorticoids (steroid) hormones.
The General Adaptation Syndrome (GAS)
The GAS is a universal…
Nervous System: In order to achieve its function, the nervous system is divided into two major parts i.e. The Central Nervous System (CNS) and Peripheral Nervous System (PNS). The central nervous system is basically made up of the brain and spinal cord and has the main function of receiving information from the body and sending out instructions. While the brain is protected by the skull, the spinal cord is guarded
Nervous System Lymphoma page literature review "Primary Central Nervous System Lymphoma The primary central nervous system lymphoma The primary central nervous system lymphoma is a cancer type that is very rare, and affects the central nervous system i.e. spinal cord, brain, brain coverings, optic nerves, or the eyes. The cancer being referred to as a lymphoma indicates that its cells are lymphocytes which are a white blood cell type. Primary central nervous
The efferent division of the peripheral nervous system carries out the motor commands that are sent from the central nervous system. These commands or signals are then sent directly through the nerve fibers of the peripheral nervous system to the target organs where they will then be signaled to perform the desired action (Martini, Nath, & Bartholomew, 380). The peripheral nervous system can be further broken down as being a
What happens is this over production of neurons results in a kind or "pre-programmed 'suicide' mechanism called apoptosis" (Marino, 2010). So if the brain kills off these neurons on purpose, what happens to the dead neurons? Journalist Melissa Marino asserts that the body must dispose of the dead neurons or else the body's immune system is in trouble. Interestingly, Dr. Bruce Carter (a biochemistry professor) of Vanderbilt has discovered the
Nervous System The major structures of basal ganglia are pallidum, substantia nigra, subthalamic nucleus, and striatum. They are inappropriately named because the name striatum refers to all major components of basal ganglia. However it was used to refer to only one of the structures. The general function of basal ganglia is to take part in learning and motor control. Is called motor cortex, receives its primary input from the ganglia structures The
Parkinson's Disease The human central nervous system is a miraculously designed functional piece of our bodies that helps us conduct the most essential tasks to help in our survival. It is therefore very important to investigate and understand how this system functions and operates. In this investigation it is also useful to understand how disease and malfunction of this system are affected. The purpose of this essay is to describe the
