What was the effect of thyroxine injections on the Thyroidectomized rat’s BMR How does the BMR in this case compare with the normal rat’s BMR?
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 gland has been removed in a rat that is Hypophysectomized?
Prepubertal removal of the pituitary gland, which in young animals influences sexual maturation, reduces significantly the amount of retinal photoreceptor destruction when the rats are exposed to continuous illumination in adulthood.

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 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.
Which hormone stimulates the breakdown of polymerized glucose?
Insulin and glucagon are potent regulators of glucose metabolism.
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.
Why didn’t the administration of TSH have any effect on the metabolic rate of the Thyroidectomized rat?
Referring to Activity 1, why didn’t the administration of thyroid-stimulating hormone (TSH) have any effect on the metabolic rate of the thyroidectomized (Tx) rat? The Tx rat lacked a thyroid gland so the TSH had nothing to act on. Thyroxine increased the baseline metabolic rate in each rat.
How do you calculate oxygen consumption per hour for this rat?
Calculate the oxygen consumption per hour for this rat using the following equation. ml O2 consumed/1 minute x 60 minutes/hour = ml O2/hour Enter the oxygen cnsumption per hour in the field below and then click Submit to display your results in the grid. You answered: 384 ml O2/hr 2i.
When a patient is taking propylthiouracil PTU what labs are monitored?
Lab Test Considerations: Thyroid function studies should be monitored prior to therapy, monthly during initial therapy, and every 2–3 mo throughout therapy. WBC and differential counts should be monitored periodically throughout therapy. Agranulocytosis may develop rapidly and usually occurs during first 2 mo.
What are the adverse effects of propylthiouracil quizlet?
