Adrenal gland

The Effects of Overtraining on the Adrenal Gland, With a Focus on Cortisol and Adrenal Medullary Response As a society, we generally view exercise such as running, swimming, boxing, or other forms of aerobic training, as positive acts towards maintaining our health and stress levels. Even so, two things that are often not acknowledged when considering exercise are moderation and recovery. Paired with aerobic exercise, the absence of adequate moderation and recovery can result in overtraining. Overtraining inflicts chronic stress on the body, resulting in detrimental and devastating effects on the adrenal gland, a major integrating center related to our stress response, regulation, and maintenance. Overtraining produces physical stress which…

Adrenaline refers to a natural stimulant created in the medulla in the adrenal organs. And also partly by certain parts of the central nervous system's neurons. In a few minutes time amid a distressing circumstance, adrenaline is immediately discharged into the blood, sending impulses through the autonomous nervous system to organs to make a particular reaction, for instance the production of sweat and saliva, pupil dilation and heart rate. It is responsible for the human fight or flight…

basal metabolic rate. B) up regulate beta receptors C) impair body growth. D) decrease the effects of norepinephrine on the heart and blood vessels. E) decrease protein synthesis. ____ 67.

Adrenoleukodystrophy (ALD) is a condition which affects the ability of adrenal glands to produce adrenaline and myelin, which insulates the nerves in the brain and spinal cord. This diminishes the ability of the brain to communicate effectively with the rest of the nerves. This condition was initially identified in the early 1900s and was originally called Schilder-Addison disease (2). The cause of this condition originates in the peroxisomes, which are tiny structures in the cell which assist…

and the constriction or dilation of blood vessels and airways in the lungs known as bronchioles (You & Your Hormones). The autonomic nervous system is made up of two parts, the sympathetic nervous system and the parasympathetic nervous system. The sympathetic nervous system triggers the fight or flight response, providing the body with bursts of energy so it can respond properly to potential dangers. The parasympathetic nervous system promotes the rest and digest response that is responsible for…

Jerry’s death, which took a mental toll on me. It made me feel an abundance of sadness. This event was a stressor that affected me socially. For the first few days after finding out about what happened, I isolated myself from everyone except my boyfriend, Skyler. I dreaded talking to people because the first thing they would ask me is, “How are you?”. I avoided this question because reliving the grief only drained me further. I was so stressed out about the event that I felt emotionally…

An anatomical change that Addison's disease can have on the nervous system is hyperpigmentation. With the insufficient levels of glucocorticoids, found in the blood, causes the pituitary gland to release more adrenocorticotropic hormone, or ACTH. In some cases, parts of this hormone are converted into melanocytes, which initiates production of melanin. This leads to darkening of skin cells in areas, such as 'Palmar creases, flexural areas, sites of friction, recent scars, vermilion border of the…

Congenital adrenal hyperplasia is the overdevelopment of the adrenal glands from birth. In a healthy person, cortisol is used to decrease the release of adrenocorticotropic hormone. ACTH is used by the pituitary gland which stimulates the adrenal gland. However, people with CAH have a genetic limitation where they are unable to produce correct amounts of cortisol. Without cortisol to exert a negative feedback on ACTH, it continues to be secreted causing the adrenal gland to secrete larger…

You can feel a rush of energy go through your body. Your hands start to shake, you are alert, the energy you have is through the roof. It’s called adrenaline. The hormone secreted by the adrenal glands, especially in conditions of stress, that gives you that extreme rush of energy that makes you feel like you can do almost anything. Most of the cases, when you get an adrenaline rush, are in fight or flight situations. The fight-or-flight response is a physiological reaction that occurs in…

the past year, thirty-one percent of men report the same (compared to 25 percent in 2014). When stressed the body shifts resources to fighting off the perceived threat. This response is known as the fight and flight response. Nervous system signals the adrenal glands to release adrenaline and cortisol. Stress causes the body to release the hormone cortisol, which is produced by the adrenal glands. Cortisol is important to regulate blood pressure and the normal functioning of many body systems…
