Endocrine gland

Circadian Rhythm – a cycle that tells the body when to rise, sleep, eat which regulates many physiological processes. The internal body clock is affected by cues. Like sunrise and temperature. According to Professor Russell Foster in 2007, an Oxford University Neurologist said that student would gain more if their classes start in the afternoon. Forcing a student who arrives in the morning could be a result of poor memory and stress. He also added that teenager's body clocks between two hours…

cephalic, gastric, and intestinal. The main component of gastric secretion is HCL which is a product of the parietal cells. The parietal cells are epithelial cells that secrete HCL and essential factors. Parietal cells are located in the gastric glands in the lining of the fundus and in the body of the stomach. The capacity of the stomach to secrete HCL is related to amount of parietal cell. Parietal cells accept receptors for three stimulators of acid secretion which are Acetylcholine,…

1. The thyroid gland secretes thyroxine also known as T4 which maintains metabolic rate of all cells and processes of cell growth and tissue differentiation. 2. Calitonin is secreted by the thyroid gland and maintains calcium and phosphorus blood levels by inhibiting the transfer of calcium from bone to blood, increases calcium storage in bone, and increases renal exertion of calcium and phosphorus. 3. The parathyroid gland secretes parathyroid hormone or parahormone which regulates calcium…

affects the Thyroid gland. Normally, the immune system protects the body from infection by identifying and destroying bacteria, viruses, and other potentially harmful foreign substances…but in autoimmune diseases, the immune system attacks the body’s own cells and organs. Graves’Dissease is the most common cause of hyperthyroidism in the United States. Hyperthyroidism is a disorder that occurs when the thyroid gland makes more thyroid hormone than the body needs. Thyroid gland makes to…

Glands in the endocrine system is what produces all of the hormones in our body to keep our body in homeostasis. There are nine glands in our body. The thyroid gland produces T3 and T4 hormone that helps to regulate our metabolism. The parathyroid glands produce PTH in which our muscles need to operate in a healthy way. We also have a pineal gland, pituitary gland, adrenal glands that sit on top of our kidneys and produce adrenaline, the…

is a disease of the thyroid gland; a part of the endocrine system. The thyroid gland is located in the front of the neck. The endocrine system is responsible for all the chemical interactions in our body e.g. hormones. This is an autoimmune condition where the immune system attacks the cells of the thyroid gland. It results in the inflammation and destruction of the gland, resulting in hypothyroidism. [3] Normal functioning of the thyroid gland: A healthy thyroid gland releases the correct…

common endocrine disorder is known as adrenal insufficiency. This is where the adrenal gland releases too little of cortisol or aldosterone. Addison’s disease is a type of adrenal insufficiency. Symptoms likely include fatigue, upset stomach, dehydration, and skin changes. Cushing’s Disease is another endocrine issue. It is caused by an overactive adrenal gland. Some symptoms include obesity and increased thirst. It is common in children who take corticosteroids. Hyperthyroidism is another…

The role of the endocrine system is the production of hormones; they consist of a collection of glands which secrete special chemicals to function different parts of the body. Endocrine glands release their chemical messengers into the bloodstream; this is where the circulatory system is involved in the process. On the cells of organs are customized receptors…

which stimulate the muscle to move away from the needle. This happens in a fraction of a second. Introduction of Endocrine System The endocrine system is the vast network of glands in the body that is responsible for controlling long term regulation of the body; example of these would be the blood sugar levels, body temperature, and digestion. The endocrine system is made up of glands which release hormones into the blood stream to send messages to different parts of the body ranging from…

These hormones circulate in the bloodstream in very low concentrations. Moreover, hormones exercise their effects on endocrine and non-endocrine target organs by binding to the cell surface or intracellular receptors. According to Carolyn Johnstone (2014), hormone production and release are controlled by the nervous system and by hormonal feedback mechanisms. The endocrine glands produce hormones or chemical messengers that are secreted into the interstitial fluid, diffuse into blood capillaries…
