Question
Explain the pituitary-hypothalamus relationship. It might help to use examples of hormones in your explanation and explain the difference between the anterior pituitary and posterior pituitary in relation to the hypothalamus.
How does the term tropic relate?
Discuss the role of hormones in maintaining blood calcium levels. When explaining the specific effects of these hormones make sure to include the details of how blood calcium levels would increase or decrease (again consider the targets).
Discuss the role of hormones in maintaining blood sugar levels. Make sure to explain what cells specifically release the associated hormones and their specific effects (when explaining the specific effects of these hormones make sure to include the details of how blood sugar levels would increase or decrease (again consider the targets). Besides the pancreas what other glands are involved with blood sugar?
Explain the difference between Type I versus Type II diabetes?
Discuss the role of hormones in maintaining osmoregulation. Should be able to discuss two key hormones and their targets/effects.
Discuss the role of hormones in social/mate-pair bonding. Should be able to discuss two key hormones and their targets/effects.
Explain how thyroid hormones (T3/T4) and growth hormone are involved with the growth of an individual. What other functions do these hormones do besides growth?
Discuss the hormones involved with stress responses in the body.
Explanation / Answer
the pituitary-hypothalamus relationship.
generally the hypothalamus stimulates cellular activity in various parts of the body by directing the release of hormones from the anterior and posterior pituitary glands.
hypothalamus activate the anterior & posterior pituitary through chemicals these are delivered to the anterior pituitary through blood vessels in the infundibulum. The releasing and inhibiting hormones are produced by specialized neurons of the hypothalamus, called neurosecretory cells.
The anterior lobe produces and releases hormones.
Anterior Lobe Hormones:
The posterior lobe does not produce hormones this is done by nerve cells in the hypothalamus—but it does release them into the circulation.
Posterior Lobe Hormones:
the term tropic relate to
2 of a hormone influencing the activity of a specified gland.
the role of hormones in maintaining blood calcium levels
generally the parathyroid hormone (PTH), secreted by the parathyroid glands, is responsible for regulating blood calcium levels it is released whenever blood calcium levels are low. PTH increases blood calcium levels by stimulating osteoclasts, which break down bone to release calcium into the blood stream.
Calcitonin, which is produced by your thyroid gland, serves to lower blood calcium levels. It counters the actions of parathyroid hormone.
the role of hormones in maintaining blood sugar levels
Insulin, which lowers blood sugar, and glucagon, which raises it
when the blood glucose level falls to dangerous levels the alpha cells of the pancreas release glucagon, a hormone whose effects on liver cells act to increase blood glucose levels. They convert glycogen into glucose.
the another hormone is released from beta cells found in the Islets of Langerhans in the pancreas. This hormone, insulin, causes the liver to convert more glucose into glycogen.
the difference between Type I versus Type II diabetes
the total lack of insulin is nothing but type 1 diabetes
insulin secreation is there but cannot use insulin effectively is called type 2 diabetes
Differences between type 1 and type 2 diabetes Type 1 diabetes Type 2 diabetes Symptoms usually start in childhood or young adulthood. People often seek medical help, because they are seriously ill from sudden symptoms of high blood sugar. The person may not have symptoms before diagnosis. Usually the disease is discovered in adulthood, but an increasing number of children are being diagnosed with the disease. Episodes of low blood sugar level (hypoglycemia) are common. There are no episodes of low blood sugar level, unless the person is taking insulin or certain diabetes medicines. It cannot be prevented. It can be prevented or delayed with a healthy lifestyle, including maintaining a healthy weight, eating sensibly, and exercising regularly.Related Questions
