Elevated levels of testosterones results in feedback inhibition when acting upon the _______. o Pituitary gland. o Hypothalamus. o Both A and B. o Neither A or B.
answer is both A and B
REASON; ELEVATED levels of testosterone results in feedback inhibition when acting upon the pituitary gland and hypothalamus. it inhibits the formation of LH , FSH & GnRH
Elevated levels of testosterones results in feedback inhibition when acting upon the _______. o Pituitary gland....
Growth factor is a hormone that is released from the pituitary gland. Low levels of growth factor can result in dwarfism. To determine if dwarfism is a neurological disease, you would assess the function of which brain region? Select one: A. thalamus B. corpus callosum C. hypothalamus D. medulla oblongata E. hippocampus
11. During early development, high levels of testosterone cause the __________ to become __________ in males than it will become in females--not subjected to elevated levels of testosterone: a. lateral hypothalamus/smaller. b. medial preoptic area/larger. c. ventromedial area/smaller. d. medial preoptic area/smaller. 12. In response to the ingestion of large amounts of water and the potential loss of sodium as the body attempts to maintain homeostasis, the __________ secretes __________ which functions to __________: a. anterior pituitary gland: vasopressin: conserve water. b. thyroid gland: thyroxin: conserve energy. c. pineal...
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.
6 In the condition hyperthyroidism, patients have elevated levels of both T3 and T4 due to a malfunction of the immune system that causes the thyroid gland to overproduce thyroid hormones. Do you think the negative feedback loops would lead to high levels of TSH or low levels of TSH? Explain. 16 90 In case 3 of Exercise 16-4 (p. 437), we saw that Professor Purple had insufficient antidiuretic hormone (ADH). However, the opposite condition can also occur in which...
a)
Considering the Case Study, what are T4 and
T3?
1. T3 is a hormone produced by the thyroid gland, and
T4 is the thyroid inhibitor produced by the
hypothalamus
2. both are hormones produced by the hypothalamus that stimulate
function of the thyroid gland
3. T4 is a hormone produced by the pituitary gland
that stimulates production of T3 by the thyroid
gland
4. both are hormones produced by the thyroid gland
b) why are TSH levels markedly decreased?...
You demonstrate that fluoride ion inhibits the conversion of 2-phosphoglycerate to phosphoenolpyruvate and that elevated levels of fluoride ion completely abolished glycolysis in the cultured normal liver cells. However, you still detected 14CO2 production when the normal liver cells were incubated with 14C-1 labeled glucose. You also test cultured liver cells obtained from a South African patient who suffers from jaundice (a yellow discoloration of skin and sclera due to too much bilirubin), kidney failure, hemoglobinuria (aggregation of oxidized hemoglobin),...
Mavis Trippe is a 41 – year-old woman who has worked at the cosmetics counter of the local department store for many years. Mavis’ colleagues in cosmetics noted that her physical appearance had change – her features had become coarse, her lower jaw was protruding, and her teeth had separated. They were concerned that Mavis might have a health problem, and one of the colleagues volunteered to have a talk with her. Mavis was a little hurt at their observations,...
Question 33 When comparing feedforward and feedback control systems, mathematical understanding of measured disturbance is necessary in those systems O Feedback control systems O Feedforward control systems Both feedforward and feedback control systems Neither feedforward nor feedback control systems
