Quick Answer: If an animal has been thyroidectomized, what hormone(s) would be missing in its blood?

What was the effect of TSH on the Thyroidectomized rat?

The baseline metabolic rate increased in each rat. What was the effect of thyroid-stimulating hormone ( TSH ) injections on the normal rat’s BMR? The effect of TSH was to increase the normal rat’s BMR. What was the effect of TSH injections on the thyroidectomized rat’s BMR?

What was the effect of thyroxine injections on the Thyroidectomized rat?

what was the effect of thyroxine injections on the mormal rat’s BMR? The hypophysectomized rat bmr increased with tsh. the bmr was just below the normal rat but still lower the syringe amount was a little too low.

What effect did the administration of calcitonin injections have on the calcitonin treated rat?

The calcitonin increased vertebral bone density in the rat. The calcitonin injections resulted in osteoporosis in the rat. The calcitonin had little or no effect on vertebral bone density in the rat.

What do you think will happen after you inject thyroxine into three rats?

What do you think will happen after you inject thyroxine into the three rats? The normal rat will become hyperthyroidic but will not develop a goiter. The normal rat will become hypothyroidic and develop a goiter.

What hormones will be missing in the rat that was Hypophysectomized?

If an animal has been hypophysectomized, what effect would you expect to see in the hormone levels in its body? TSH levels will be missing because the pituitary gland is removed, so decreased metabolic rate. What was the effect of throxine injections on normal rats BMR?

How does PTU affect the body?

PTU inhibits iodine and peroxidase from their normal interactions with thyroglobulin to form T4 and T3. This action decreases production of thyroid hormone. PTU also interferes with the conversion of T4 to T3, and, since T3 is more potent than T4, this also reduces the activity of thyroid hormones.

Which patient would most likely be diagnosed with Addison’s disease?

Which patient would most likely be diagnosed with Addison’s disease (view Table 4.1 in your textbook)? Why? Patient 4 has low cortisol levels, so they would most likely be diagnosed with Addison’s disease. The low cortisol levels are caused by the destruction of the adrenal cortex.

Which gland secretes the hormone that controls metabolism?

Through secretion of its hormones, the pituitary gland controls metabolism, growth, sexual maturation, reproduction, blood pressure and many other vital physical functions and processes.

What hormone stimulates the breakdown of polymerized glucose?

Insulin and glucagon are potent regulators of glucose metabolism.

What effect will the saline injections?

Common side effects of Normal Saline include: fever, injection site swelling, redness, or.

What effect will the calcitonin injections?

Calcitonin salmon injection is used to treat osteoporosis in postmenopausal women. Osteoporosis is a disease that causes bones to weaken and break more easily. Calcitonin salmon injection is also used to treat Paget’s disease of bone and to quickly reduce calcium levels in the blood when needed.

What is a glucose standard curve and why did?

What is a glucose standard curve, and why did you need to obtain one for this experiment? Glucose standard curve is a graphic tool to demonstrate the relationship between optical density and glucose concentration. You need it because you don’t have too many samples to compare with so you have to extrapolate.

Why does oxygen consumption have to be normalized when comparing two animals?

Terms in this set (13) the larger animal consumes more oxygen per minute than the smaller animal. smaller animals have a lower surface-to-volume ratio, thus a larger relative heat loss to the environment per unit time.

How do you calculate metabolic rate using oxygen?

Therefore heat production can now be calculated from oxygen consumption by multiplying the volume of oxygen used by 4.8 cal/mL of oxygen consumed (step 6). However, metabolic rate is typically expressed as Cal, and there are 1,000 gram cal/Cal, so divide by 1,000.

Which of the following statements describes the effect of hormones secreted by the thymus gland?

Which of the following statements describes the effect of hormones secreted by the thymus gland? These hormones stimulate the development of the immune system. These hormones lower blood Ca2+levels. PTH increases blood calcium levels but calcitonin decreases blood calcium levels.
