Comparing The Endocrine System And Stress

There are three different theories that are used when talking about how we react to stress through the physiological aspect or the psychological aspect. The first is part of the physiological aspect of stress called the Cannon Fight or Flight theory which was proposed in 1914. Fight or Flight response is a physiological stress response that evolved to help organisms to survive immediate danger. The theory states that when an organism, human being or animal, faces imminent danger (acute stressor) the body arouses quickly and is ready to act via two different systems. They are the sympathetic nervous system and the endocrine system. The sympathetic nervous system stimulates the adrenal medulla which is part of the endocrine system and is the region that produces the hormones such as adrenaline and noradrenaline. These hormones increase heart rate, blood flow, and glucose levels to prepare the body for an emergency. This response from the body suggests that the body knows how to protect itself and reach homeostasis. These two systems work together to either fight against the danger or flight away from the danger. Lord, King and Pfister in 1976 studied the Fight or Flight response in animals through a very unethical study. They administered chemicals on male hooded Wistar rats which inhibited the neurotransmitters from functioning normally. This made it very difficult for the rats to escape an electric shock. The results of the study suggest that the Flight or Fight response

Stress has a huge impact on the immune system. The immune system is interconnected. For example the immune, nervous, and endocrine system is linked through specialized communication pathways involving hormones, neurotransmitters, neuropeptides, and immune cell productions. Stress reactions can directly affect the various response systems and how they handle the neuroendocrine-products. This stress reaction directly affects the hypothalamus and pituitary peptides through the sympathetic branch of the autonomic nervous system. Some of these stressors might be life events, anxiety, and excitements.

The nervous system uses sensory receptors, nerves and your brain to control your cells, and acts quickly. The endocrine system uses your circulatory system and hormones to care for your cells and acts more slowly. The reproductive system and endocrine systems use hormones to function. The nervous and endocrine systems are connected by sending information to the hypothalamus and uses the autonomic nervous system to transmit what activity needs to take place in the body. This activity might be what hormones are needed, or what sensations the body feels. While the nervous and endocrine systems send information to the hypothalamus, the reproductive system receives information from the hypothalamus. So all three systems do work together, although

The central nervous system is composed of the brain and spinal cord and the peripheral nervous system is composed of the body’s sensory receptors, muscles, and glands. The peripheral nervous system is made up of somatic and automatic. Somatic is the voluntary movement of our skeletal muscles. When we hear the bell ring, our somatic nervous system carries the message to the brain and the brain reports back to our muscles. The autonomic nervous system controls our glands and muscles in our internal organs. Some things this nervous system does is taking control of our digestive system and our heart beat. There are two functions of the autonomic nervous system- the sympathetic and the parasympathetic nervous system. The sympathetic nervous system arouses and expands energy. If someone gets excited or nervous in a situation, their blood pressure will rise, their digestion will slow down, their heartbeat will accelerate, their blood sugar will rise, and they will sweat to cool down. The parasympathetic is the opposite. It tries to conserve energy by decreasing your heartbeat, lowering your blood sugar, and so

Learning Objective 1: 18.1 Compare control of body functions by the nervous system and endocrine system.

The nervous and endocrine systems are what control most of the body. The nervous system includes the brain, spinal, cord and nerves. The endocrine system consists of various hormonal glands such as the pituitary. These two systems interact closely since they both have a part in controlling

The aim of this review is to discuss the mechanisms by which the nervous and immune systems interact to affect each other during periods of stress (psychological and physiological), the specific effects of cortisol-mediated stress on the immune system based on the magnitude and duration of the stressor, and the models proposed to explain these effects.

Once your brain has decided there’s a danger, in stressful situations, it sends immediate nerve signals down your spinal cord to the pituitary gland and all the ways to the kidneys where your adrenal gland resides, which is how adrenaline is released. Once released, adrenaline increases the amount of sugar in your blood, increases your heart rate and raises your blood pressure. The brain’s hypothalamus also sends signals to your pituitary gland, which allows the body to release Cortisol: Cortisol is a stress response that allows the blood and sugar pressure to remain high, which helps when escaping from danger. For instance, in an interview, which presents a challenge, simulated the same biological reaction that a threat to your life does.

The human body contains various structures and organs that allow regulations and maintenance of homeostasis. Foundation is built through the framework of the skeletal system, motion is possible due to the muscular system humans have and other body systems that allow humans to perform daily actions. All of this anatomical structures are possible due to the two main controlling system found in the body; the nervous system and endocrine system. The nervous system can be considered as information processor of the human body, but for it to be more effective in transferring and processing information; it works in tandem with the endocrine system. The purpose of the endocrine system is to act in response to the information the

Meyer et al 2014 In vertebrates the stress response is an evolutionary conservative process mediated by the HPA access and allows organisms to respond rapidly to unpredictable changes in their environment. It is initiated when higher brain centers perceived and endogenous or exogenous noxious stimuli that are in homeostasis and how many it’s release of good corticoids from the adrenal cortex. Elevated levels of circulating clinical records exert a variety of catabolic and Terry productive anti-gross and immunosuppressive effects that mobilize and repartition under detailed organisms restore homeostatic balance. Other than physiological response to short-term stress is adaptive long-term stress occurring over weeks to months may lead to pathological syndrome of distress characterized by amino suppressive decreased reproduction and diminish growth. According Lee measures of population performance such as survival for productive output and abundance may be reduced as a proportion of distress individuals it a population increases. .

The endocrine system is the body system that deals with hormones and controls the body’s daily activities by producing specific chemicals. The endocrine system is also in charge of making sure that the body’s functions are coordinated and working properly. An example of this would be having the same body temperature at all times and falling asleep and waking up. Hormones play a major part in the endocrine system. Hormones are the chemical product of an endocrine gland. There are different hormones that have different jobs. Certain hormones can turn on, turn off, speed up, or slow down the activities that different organs and tissues take part in. Other hormones can regulate metabolism, growth, mood, and organ function. All of the organs involved in this body system work together but are located in different

Nervous System: Endocrine system works along side the nervous system by sending hormones to cells. These hormones provide feedback to the brain and affect neural processing. Also, the reproductive hormones affect the development of the nervous system.

Stress affects the body in many different ways. Many doctors estimate that stress is involved in more than half of all illnesses (Sapolsky, 21). Stress may cause or prolong an illness or increase its severity. Epinephrine and norepinephrine are hormones that are released during a stress reaction that affect organs throughout the body. As a result from the hormones being secreted, the heart begins to beat more rapidly, muscle tension increases, blood pressure raises, and heavy breathing may occur. This reaction is known as the fight-or-flight response. The fight-or-flight response energizes the body to either confront or flee from a threat. Heredity, learning, and injuries all play a role in determining where or when a stress related illness may occur in a particular individual (Sapolsky, 22).

Psychological and physical well-being and the overall quality of life are under a constant threat of stress and thus, psychological and medical sciences have long been concerned with studying stress response. Cox (1979) claimed that because of the poor understanding and defining it, the concept of stress tends to be rather elusive. The term, “stress”, commonly describes any physchological or physical alteration that deranges the organism’s homeostasis (or balance). This essay reviews some of the biological factors involved in stress and it has been organized in the following way. The paper begins by briefly introducing the concept of stress. It will then go on to discus and describe the automatic response (fight or flight reaction),

The endocrine system in the human body stores a chemical known as hormones. Hormones are released by endocrine glands into the bloodstream and travel throughout the body carrying messages. A hormonal impulse is similar to a nerve impulse only much slower. The messages carried by the hormones trigger different behaviors. Hormones can affect behavior in many ways such as: Mental activity or tiredness, boredom or excitement, sexual
