Frequent question: Which hormone would be missing in a Thyroidectomized animal?

If an animal has been thyroidectomized, what hormone(s) would be missing in its blood? it would be missing Thyroxine in its blood, also known as t4, since thyroid gland is removed.

What hormone is a Thyroidectomized rat missing and how does this affect their metabolic rate?

In case of thyroidectomized rats there is no thyroid gland to stimulate. Hence, there is no effect of injecting thyroid-stimulating hormone (TSH) on the thyroidectomized rats. 10. The administration of TSH injection into the hypophysectomized resulted in the increase of basal metabolic rate (BMR).

What was the effect of TSH on the Thyroidectomized rat?

There was no effect on the thyroidectomized rat’s BMR with the injection of TSH because there was no thyroid gland to stimulate.

What was the effect of TSH injections on the Thyroidectomized rats BMR?

There was no effect on the thyroidectomized rat’s BMR with the injection of TSH because there was no thyroid gland to stimulate.

What hormone is a hypophysectomized rat missing?

4. If an animal has been hypophysectomized, what effect would you expect to see in the hormone levels in its body? For the hypophysectomized rat, the TSH will be missing due to the missing pituitary gland.

Which hormone is involved in metabolism?

The basal metabolic rate of the body is controlled by the hormones T3 and T4, produced by the thyroid gland in response to the thyroid stimulating hormone (TSH), produced by the anterior pituitary.

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

What do you think will happen after you inject TSH into the three rats? The normal rat will become hyperthyroidic and develop a goiter.

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

What effect did the administration of estrogen injections have on the estrogen treated rat? The estrogen injections did increase the rats vertebral bone density and is indicated by the negative T score.

Which hormones stimulates the breakdown of polymerized glucose?

Insulin and glucagon are potent regulators of glucose metabolism.

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

Why? Patient 4 has low cortisol levels, so they would most likely be diagnosed with Addison’s disease.

Why didn’t any of the rats develop a goiter after thyroxine injection?

Why didn’t any of the rats develop a goiter after thyroxine injection? In all cases, TSH levels were not elevated by the thyroxine injection. … The injection decreased the negative feedback mechanism on TSH.

  • normal rat has highest bmr because it has glands required to stimulate and regulate the release of the thyroid hormones.

What was the effect of thyroxine on the hypophysectomized rat?

The administration of thyroxine injections on the hypophysectomized rat resulted in increased basal metabolic rate (BMR). However the BMR was still on the lower side in comparison to the basal metabolic rate seen in the case of normal rats with thyroxine.

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.

Why does thyroxine increase metabolic rate?

Thyroxine increases the number and activity of mitochondria in cells by binding to the cells’ DNA, increasing the basal metabolic rate. Administration of thyroid hormones, such as thyroxine, causes an increase in the rate of carbohydrate metabolism and a rise in the rate of protein synthesis and breakdown.
