Adrenal medulla

by stimulating the systemic vascular resistance and the raise of the blood volume, therefore the blood pressure too.Angiotensin II also stimulates the production of aldestorne by the adrenal cortex.Aldosterone provoke kidneys to reabsorp more sodium ions and water. Due to the sympathetic stimulation,the adrenal medulla secretes epinephrine and norepinephrine,which raise the heart rate and respectively,the cardiac…

medication is used for a few conditions such as anaphylaxis, cardiac arrest and superficial. Epinephrine also releases a hormone secreted by the adrenal glands that increases rates of blood circulation, breathing, and carbohydrate metabolism and prepares muscles for exertion. this is known as adrenaline. Adrenaline is produced and released from the adrenal glands and its major action, together with noradrenaline, is to prepare the body for fight or flight modes. Adrenaline targets various…

This hormone acts on the parts of the brain involved with responsiveness and fear. This neurotransmitter is released into the blood from the adrenal medulla and from nerves called adrenergic nerves. Nerve pathways within areas of the brain that regulate pleasure and emotional reward are regulated by dopamine. Disruption of circuits that communicate using dopamine in other brain areas appear connected…

1 Hypothalamus – a small region of the brain that is a major link between the nervous and endocrine system. The hypothalamus controls the autonomic nervous system and regulates body temperature, hunger, thirst, fear, rage, and sexual behavior. The hypothalamus control feeling such as pain, stress, and emotional experiences. (1) 2 Pituitary gland – the “master endocrine gland” because it secretes many hormones that control other endocrine glands. It is a “pea-shaped structure that attaches to…

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.…

As we know endocrine and nervous system work together. The way they work together is through communications. This systems consists on glands which secrets special hormones and these hormone goes around in the body as messenger. The organs who carry these type of hormones in the body are blood stream, organs and body tissues. The way they are connected is via brain which connect with two communication systems and the hypothalamus is tiny collection of Nellie which controls behaviour placed at the…

Nervous System 1.1 CO – Cardiac output CO may be increased or decreased by autonomic nervous system activity that travels between reflex centers in the medulla oblongata and the SA node of the heart. Control of CO is governed by two kinds of mechanisms: primary mechanisms, which operate quickly for acute…

track. Due to the intensity of the track and the distance their blood glucose levels will get very low and the alpha cells will be struggling to secrete enough glucagon to make sure the liver can keep up with the bodies glucose demands. Even with the adrenal glands secreting epinephrine the liver still won’t be able to produce enough glucose to keep the blood glucose levels within the normal range. The first response to this is the stimulation of…

Neuroblastoma is a malignant hemorrhagic tumor composted principally of cells resembling neuroblasts that give rise to cells of the sympathetic system. Cancer starts when cells in the body begin growing out of control. Neuroblastoma is a type of cancer that starts in early forms of nerve cells found in an embryo/ fetus. Neuroblastoma is by far the most common cancer in infants less than 1 year old. Neuroblastoma is accountable for about 6 percent of all cancer in young children. The prefix…

endocrine system negatively affecting the rest of the body are as follows. Addison disease caused by the destruction of the Adrenal Cortex results in Adrenocortiroid deficiency messing up the balance of salts, Vitamin K and, water in the body. This disruption causing skin darkening, salt cravings, Hypoglycemia, low blood pressure and, weight loss. Adrenal Adenoma or an Adrenal Tumor may result in the overproduction of Cortisol (Cushings), Aldosterone (Aldosteronism) and, Androgens. Cushings…
