WHY IS HYPOTHALAMUS CONSIDERED TO BE A LINK BETWEEN THE ENDOCRINE AND NERVOUS SYSTEM?
Step by step
Solved in 2 steps
- Why is the hypothalamus considered part of both the nervoussystem and the endocrine system?Neuroendocrine glands are glands that are made up of both nervous tissue and endocrine tissue. This means that they can be directly stimulated by the nervous system to produce or release hormones. i) Identify two endocrine glands that are considered to be neuroendocrine. Be specific. ii) Describe a situation/example for each, that demonstrates this function.Neuroendocrine glands are glands that are made up of both nervous tissue and endocrine tissue. This means that they can be directly stimulated by the nervous system to produce or release hormones. i) From what you have learned so far in the course, identify two endocrine glands that are considered to be neuroendocrine. Be specific. ii) Describe a situation/example for each, that demonstrates this function.
- What is the mechanism of receptor-associated hormonal disorder?What is one major difference between the endocrine system and the nervous system?a) How does the body's hormonal response to short-term stress differ from the body's hormonal response to long-term stress? In your answer, provide the names of the hormones released, the glands from which they are released, and the effects on the body. b) Provide 2 reasons (as discussed in class) why long-term stress is harmful to our physical health.
- What are the major functional differences between the endocrine and the nervous system?Although the pituitary gland is often referred to as the master gland of the body, the hypothalamus exerts some control over the pituitary gland. How does the hypothalamus control both anterior and posterior pituitary functioning?On a realistic drawing of the endocrine glands in the body (such as a photocopy of Figure 17.1), indicate the gland associated with (a) cretinism, (b) diabetes mellitus, (c) acromegaly, (d) secreting thyroid-stimulating hormone, (e) secreting a hormone that regulates the nightly activities of our circadian rhythms, (f) secreting estrogens, (g) secreting DHEA.
- Name the basic hormones of neurohypophysis. Where are they synthesized? What are their structures by chemical nature? What are their functions?What roles does the endocrine system play in the body?State what the different parts of the pituitary gland are called and how they differ. b) Explain the physiological significance of the portal system of the hypothalamus and pituitary gland c) What hormones are produced by different parts of the pituitary gland? Enter in the image below. What effects do these hormones have on the body? Give at least one example of a function for each hormone.
