It is a beautiful presentation on Endocrine glands and hormonal regulation. have a look and enjoy you study.

2. Acromegaly is a rare condition where the body produces too much growth hormone, causing body tissues and bones to grow more quickly. Over time, this leads to abnormally large hands and feet, and a wide range of other symptoms. Acromegaly is usually diagnosed in adults aged 30 to 50, but it can affect people of any age. Froehlich syndrome is characterized by increased or excessive eating that leads to obesity, small testes, and a delay in the onset of puberty. It is also common for children with Froehlich syndrome to experience the delay in physical growth and the development of secondary sexual characteristics.

3. Hashimoto's disease is an autoimmune disorder. The immune system creates antibodies that attack thyroid cells as if they were bacteria, viruses or some other foreign body. The immune system wrongly enlists disease-fighting agents that damage cells and lead to cell death. Cushing's syndrome is a disorder that occurs when your body makes too much of the hormone cortisol over a long period of time. Cortisol is sometimes called the “stress hormone” because it helps your body respond to stress. Cortisol also helps. maintain blood pressure. regulate blood glucose, also called blood sugar.

4. Pheochromocytoma is a type of  neuroendocrine tumor that grows from cells called chromaffin cells. These cells produce hormones needed for the body and are found in the adrenal glands. The adrenal glands are small organs located in the upper region of the abdomen on top of the kidneys.

6. What is an example of a zeitgeber ? They are cues given by the environment that reset the circadian rhythm. These cues literally impact the expression of our genes. The science of this process is called chronobiology . Examples of external zeitgebers in humans are environmental cues like sunlight, exercise, and eating. What is a free-running rhythm? Circadian rhythm sleep disorder, free-running type (CRSD, FRT) 1  is a disorder in which the intrinsic circadian rhythm is no longer entrained to the 24-h schedule. Normal individuals who are exposed to an environment devoid of zeitgebers develop free-running rhythms with a period longer than 24 h.
