Aldosterone's Role In Response To Acute Stress

227 Words1 Pages

The adrenal cortex is responsible for secreting corticosteroids and hormones such as: • Cortisol enables the control the body 's use of fats, proteins, and carbohydrates as well as suppresses inflammatory reactions in the body • Aldosterone which regulates the level of sodium and potassium in the body and helps maintain blood volume and blood pressure. Aldosterone is regulated by complex feedback mechanisms involving sodium and potassium levels as well as blood volume. • Androgenic steroids which are hormones that are converted elsewhere in the body to female hormones (estrogens) and male hormones (androgens) The adrenal medulla is responsible for helping the body cope with emotional and physical stress and secretes hormones such as: • Epinephrine which helps the body to respond to a stressful situation by increasing the heart rate and force of heart contractions, facilitating blood flow to the muscles and brain, causing the relaxation of smooth muscles, helping with conversion of glycogen to glucose in the liver, and other activities. …show more content…

Psychology has always been an immensely interesting subject to me so I chose to give a brief description of the adrenal glands because the impact of the adrenal medulla on the body and the mind is impressive to say the

Each conducts a different function. The adrenal cortex is the outer portion of the adrenal gland and produces steroids such as aldosterone which reabsorbs sodium and releases potassium. The adrenal cortex is vital to sustain life. The adrenal medulla is the inner part of the adrenal gland and produces adrenaline hormones such as norepinephrine and epinephrine that are used in sudden stress

The secretion of cortisol is controlled by the hypothalamic-pituitary-adrenal axis, which is a three inter-communicating regions of the body, the hypothalamus in the brain, the pituitary gland and the adrenal gland. When cortisol levels in the blood are reduced, a collection of cells in the hypothalamus release corticotrophin-releasing hormone, which causes the

Q1 The organs involved in the homeostatic system of salt regulation are pineal gland, pituitary glands, thyroid gland ,thymus, adrenal, pancreas, ovary and testis. All our bodies removes uneeded fluid by filtering your blood through your kidney, via osmosis, to draw excess water out of your blood. This requires a balance of sodium and potassium to pull the water across the wall from the bloodstream into a collecting channel in the kidney. A high salt diet will alter this sodium balance, causing the kidneys to have reduced function and remove less water resulting in higher blood pressure.

According to Martini, F., Tallitsch, R., Nath, J., (2018), the ANS functions outside of our conscious awareness and makes routine adjustments in our body’s systems (Martini, Tallitsch, & Nath, 2018, p. 450). The autonomic nervous system helps maintain the homeostasis of our bodies by regulating body temperature and coordinating cardiovascular, repertory, digestive, excretory, and reproductive functions. Efferent axons innervate the visceral organs and the efferent nerve fibers and ganglia of the ANS organize in two systems or divisions. The sympathetic division and the parasympathetic division. The sympathetic division is most active during times of stress, exertion, or emergency, also known as “flight or fight”.

Stress, Habits, and Drug Addiction: A Psychoneuroendocrinological Perspective From many studies, it is concluded that stress is a main risk factor for the growth of drug addiction and addiction relapse. But, the way the cognitive processes work in the involvement of stress on the addictive behavior is still undefined. In this paper it is suggested that stress induced some changes in the neural circuits while controlling the instrumental action that provide a potential mechanism by which stress effectively affects the growth of addiction and relapse. Drug addiction also known as substance dependence, is a major concern to the person who is said to be addicted. It affects the ones around them, including the society as a whole.

As discussed with Overtraining Syndrome and Adrenal Insufficiency, hormone levels are varying in an abnormal fashion with respect to the adrenal glands. The hypersecretions hyposecretions of adrenal gland hormones, receptor modulation of their respective target cells, and desensitization of corresponding target cell receptors produce a vast array of ill effects on many other parts of the body. For instance, in the early stages of Overtraining Syndrome, hypersecretion of cortisol is observed. Hypersecretion of cortisol, or hypercortisolism, also causes insulin resistance as cortisol is an antagonist to insulin. This can lead to the development of Type II Diabetes Mellitus and obesity.

Testosterone is a kind of anabolic hormone, which is naturally produced in the human body’s testes and adrenal glands. It is the one responsible for some natural characteristics, which include fitness and strength, bone density, competitive feelings and sex drive as well. Usually the testosterone level in men is higher than in women throughout the entire life although they tend to fall down after men reach their mid 20s. Testosterone is also responsible for puberty in both boys and girls, including growth spurts and normal sexual development. Testosterone levels in men affect both physical performance and physical appearance of a person.

INTRODUCTION The pituitary gland is a central endocrine organ that regulates basic physiological functions incuding growth, reproduction and metabolic homeostasis. It situates at the base of the brain, under the optic chiasm, inside a depression on the upper surface of the sphenoid bone, the sella turcica1 (Fig.1). Fig. 1

Kelly McGonigal felt she was doing something wrong by turning stress into the enemy. As a health psychologist her job was to help people be happier and healthier. But was afraid that what she had been teaching for the past years was doing more harm than good. For the last 10 years she told people that stress makes them sick because it increases the risk of getting sick from a common cold to cardiovascular disease. But a study that tracked 30,000 adults in the United States for eight years changed her mind about stress.

The endocrine system is such an important system to the body because it functions the bodies use of hormones. The body uses many different hormones and the endocrine system regulates these. When the glands of the endocrine system secrete the hormones, the hormones are put into the bloodstream to be sent to the different parts of the body. The glands that comprise the endocrine system are the hypothalamus, the pituitary gland, and the pineal gland which are all located in the brain, the thyroid, parathyroid, and thymus which are located in the throat, the adrenals and pancreas which are located in the body’s midsection, and the ovaries (female) and testes (male) which are located in the pelvic region. The system is so important because it regulates the body’s metabolism, growth and sexual development, digestion, heart rate, and many of the other body functions regulated by hormones.

3. Review of literature 3.1 Stress and its types: Stress is an essential mediator of human behaviour. Immediate physiological response to any type of stressor facilitates survival of the species at its maximum. Despite of normal homeostatic regulatory mechanism, the stress responses can become maladaptive. Chronic stress, for example immobilization, exposure to noise, irradiations, psychological stress can leads to a host of adverse health consequences, including cardiovascular diseases, neurodegeneration, obesity, depression and early ageing (McEwen et al, 2004).
