what is the first endocrine gland 1.) anterior pituitary 2.) hypothalamus 3.) thyroid gland
Describe the relationship among hormone of the hypothalamus and anterior pituitary.
Animal Physiology: Compare and contrast the relationship between the hypothalamus and the anterior pituitary with that of the hypothalamus and the posterior pituitary. Include differences in tissue type, mode of communication with the hypothalamus, and regulation of hormone release. 2. Explain how complex organisms rely on feedback systems to regulate various aspects of bodily functions. Also, provide an example of each type of feedback system, being sure to identify and detail specific mechanisms involved.
Using a hormone of the hypothalamic-anterior pituitary axis, describe or diagram how negative feedback loops regulate hormone levels.
Assignment: Explain the role of the hypothalamus, pituitary gland and thyroid gland in development of a goiter. Make sure to discuss each gland/organ. Your answer should be a minimum of 100 words, be specific and detailed.

The results of Felix’s thyroid function labs indicate that he has hypothyroidism. (a) Discuss the normal negative feedback loop that regulates thyroid hormone release, starting with the hypothalamus. (b) Briefly describe how the thyroid gland responds to TSH. (c) Suppose that Felix’s levels of TSH and T4 were both abnormally low. Considering the normal negative feedback loop regulating the thyroid gland, explain how these lab results are possible.
Describe the negative feedback loop that controls the secretion of ADH by the posterior pituitary?
