Endocrine system The main function of endocrine glands is to secrete hormones into the bloodstream. Hormones are chemical substances that effect the activity of another part of the body e.t.c organ. In one word, hormones serve as messengers, controlling and coordinating activities throughout the body. Fundamentally, hormones control the function of entire organs, affecting such processes as growth and development, reproduction, and sexual characteristics. Although hormones circulate throughout the

time. The most common cause of Cushing’s Syndrome is called hypercortisolism is the use of oral corticosteroid medication. The condition can also occur when your body makes too much cortisol. Cushing’s Syndrome is an endocrine disorder of the adrenal glands, it causes physical and physiological effects. Because of to much cortisol it could cause some hallmark signs: like hypertension, obesity, weakness of muscles, a tendency to develop bruises. Some typical characteristics are: rapid deposit of

associated aften with parathyroid adenoma. The patterns of secretion of hormones vary tremendously. The thyroids hormones tend have less variability than the steroid hormones and only show moderate of daily or weekly variation. The blood levels of the adrenal steroid cortisol, also shows much fluctuation Occasionally bursts of secretion followed by periods of low activity (Low blood leves occurring throughout the day).

functioning properly as it should.Note: that when the hormones enter the body they only affect the targeted organs or tissues that the receptors are targeted toward.The major organs of this system are a host of glands, the pituitary, thyroid, parathyroid, adrenal, pancreatic, pineal, the female (ovaries), and the male

threatening. Addison’s diseases occurs when your adrenal glands do not produce enough cortisol or aldosterone. Cortisol is a steroid hormone that helps your body when it experiences a traumatic event,and aldosterone is a hormone that help regulate blood pressure. Damaging your adrenal gland can also cause Addison’s disease. You can damage adrenal gland from long lasting infection or cancer from other parts of the body that has spread to the adrenal gland. A pituitary gland problem can also cause Addison’s

What is the endocrine gland? What role does the pituitary gland have associated with the endocrine gland? Why is their negative feedback when the pituitary gland is controlling the action of another endocrine gland? Knowing and understanding the role of the pituitary gland will help you infer the negative feedback involved with the pituitary gland when controlling the action of another endocrine gland. Endocrine glands are hormonal glands that are part of the endocrine system (body's main system

Addison’s Disease is a rare disorder where the adrenal glands, that’s located directly above the kidney, does not produce enough of the cortisol hormone. Addison’s disease can be separated into 2 sub conditions, primary adrenal insufficiency and secondary adrenal insufficiency. People with primary adrenal insufficiency suffer from both a lack of the aldosterone hormone and the cortisol hormone the adrenal glands produce. People with secondary adrenal insufficiency only suffers with a lack of cortisol

Hypothalamus Gland Hormones and Their Functions Katherine M. Gaub Western Dakota Tech Hypothalamus Gland Hormones and Their Functions The Hypothalamus gland is responsible for regulating certain metabolic processes and other activities of the autonomic nervous system such as, controlling the body temperature, hunger, thirst, fatigue, sleep, attachment behavior, and circadian rhythms. This gland, which is about the size of an almond, is located at the base of the brain and is near the Pituitary gland

Pheochromocytomas are a tumor that can be found inside the adrenal gland or on specialized cells of top of the adrenal gland. The adrenal glands are located on top of the kidneys and are responsible for releasing very high levels of epinephrine and norepinephrine. The inner area of the adrenal gland is called the adrenal medulla where the norepinephrine and dopamine are secreted by the cells. These cells are called catecholamine which is found inside the adrenal medulla. The catecholamine cells are responsible

The use of certain colors associated with clothing in a film can help tell a story, show a character's journey or who they are to the story, and it helps communicate ideas to the audience. In a film such as King Arthur: Legend of the Sword, the battle between good and evil is represented by light colors like white, tan, or light brown and black in clothing, but when using magic, the characters who represent “good” have blue, gold, and silver accents while “evil” characters have red, orange, and black

In the vast African Savanna, many people are sleeping at night in the middle of it all, cozy near a campfire. A twig breaks, and one of the men wake up, who later decides to go back to sleep. The sound comes again more frequently, which is when everyone has woken up. On the southern side, they see a moving animal just walking in circles around them. Everyone is afraid, but they do not know what it is… until is roars. The beast is a lion, and all of the men are sure they are going to die. This is

The amygdala, the seat of emotion and motivation, is a fascinating telencephalic component of our limbic system located in the anterior temporal lobe. Scientific advancements in the field of neuroscience have revealed that this almond shaped wonder is a versatile emotional genius contributing to various facets of cognition. The term amygdala, first mentioned by the German physician and anatomist Karl Friedrich Burdach (1819), is composed of lateral, basal and accessory basal nuclei, collectively

5. If the pituitary is so important, and Eric is not getting replacements of hormones the pituitary makes (except for the one from question 4 above), why isn’t he dead? To answer this question think through the cascade of events from the hypothalamus to effect. You will need to think about homeostatic feedback loops and the regulations of hormones. Before we can discuss why Eric is alive without a functioning pituitary gland we must first understand how the pituitary gland functions within the

In the Bible, Jesus said to disciples “Go into all the world and proclaim the gospel to the whole creation.” However, nowadays, Christians starts to cloister themselves and wants to stay in their comfort zone, just like the “royalties” at the party in “The Masque of the Red Death”. The people in the story have a party inside an abbey and locked themselves in there while the disease that devours people runs like a hungry lion outside the abbey. In the end, the pestilence comes into the abbey also

Informative Topic: Human Brain Title: “All Aboard” “Choo-choo! *possibly with toy train whistle* all aboard the train of thought. The engine behind our train of thought and the driving force of our movements, functions, and personality, the human brain is a critical organ responsible for every aspect of our existence. The train of thought, not to be mistaken with the the soul train or the mouth watering gravy train, is complex and tugs along many compartments of information. Today we will add a

these hormones is the adrenocorticotropic hormone which helps the body’s cortisol level, or stress level (Adrenocorticotropic hormone, 2013). When there is too little of the adrenocorticotropic hormone there is a high chance of poorly functioning adrenal glands or Addison’s disease which is when the body doesn’t produce enough hormones causing side effects of fatigue, loss of weight and muscle, and darkened areas on the skin (Adrenocorticotropic hormone, 2013). Effects of Sleep Loss When a person

stimulation of neural tissue, including cerebral cortex, spinal roots, and cranial and peripheral nerves. TMS can be applied as single pulses of stimulation, pairs of stimuli separated by variable intervals to the same or different brain areas, or as trains of repetitive stimuli at various frequencies. Single stimuli can depolarise neurons and evoke measurable effects. Trains of stimuli (repetitive TMS) can modify excitability of the cerebral cortex at the stimulated site and also at remote areas

The brain is the most complex and magnificent organ of the human body. It controls the muscle movements, the secretions of glands,breathing and internal temperature. Every creative thought, feeling, and plan is developed by the brain. The brain acts as the body’s control center. The human brain can be divided into the forebrain, mid-brain and hind-brain. The cerebellum and brain stem constitute the hind brain. The tectum and the cerebral peduncles form the mid-brain. The forebrain is made of the
