How can you find metastatic papillary thyroid cancer with non-avid iodine uptake?

One of the best ways is with FDG-18 PET scans. This is because non-iodine avid disease is often metabolically super-active and concentrates the radioactive glucose rapidly. This then "lights up " on the PET scan.

What are FSH and LH Pituitary Hormones?

Follicle-stimulating hormone (FSH) is a hormone synthesised and secreted by gonadotropes in the anterior pituitary gland. FSH and LH act synergistically in reproduction: * In women, in the ovary FSH stimulates the growth of immature Graafian follicles to maturation. As the follicle grows, it releases inhibin, which shuts off the FSH production. * In men, FSH enhances the production of androgen-binding protein by the Sertoli cells of the testes, and is critical for spermatogenesis. Luteinizing hormone (LH, also known as lutropin) is a hormone synthesized and secreted by gonadotropes in the anterior lobe of the pituitary gland. In concert with the other pituitary gonadotropin follicle stimulating hormone (FSH) it is necessary for proper reproductive function: * In the female, an acute rise of LH - the LH surge - triggers ovulation. * In the male, where LH had also been called Interstitial Cell Stimulating Hormone (ICSH), it stimulates Leydig cell production of testosterone.

Can animals have adrenaline rushes?

I don't know about other animals but kangaroos get adrenaline rush and its capable to kill the kangaroo within short period. When a kangaroo undergoes fright, for ex when a human tries to catch the kangaroo, the kangaroo experiences adrenaline rush. the body will stimulate all the muscle tissues and allow the kangaroo to fight against the human. "myopathy" (death of kangaroo due to muscle deterioration) might occur when it undergoes low stress threshold. This is because the energy in muscle cells is being burnt too quickly, causing kangaroo to die.

Hence, kangaroos have adrenaline rush! IT MIGHT UNDERGO MYoPATHY

Are mucus glands endocrine?

Could taking Depakote long term cause under-active thyroid?

What gland is associated with the diencephalon?

The diencephalon is located in the brain. It is composed of the thalamus (located at the top of the brain stem) and hypothalamus (located below the thalamus). The hypothalamus is related to causing the pituitary gland to release hormones.

Do you sweat more on a dry day or on a humid day if yes why?

You will sweat the same on both days if your activity is the same. It will evaporate faster on a dry day, so you will notice less sweat on a dry day.

Control of temperature endocrine activity and thirst are functions associated with?

The Hypothalamus. Most of its funstions relate to regulation of visceral activities including: cardiovascular regulation, body-temperature regulation, water and electrolyte balance, gastrointestinal activity and hunger, sleeping and wakefulness, sexual response, emotions, and control of endocrine functions through stimulation and anterior pituitary.

Where is TSH found?

Thyroid secretion hormone is secreted by the thyrotrope cells in d anterior pituitary gland

What is diffusely hyper vascular thyroid?

FINDINGS: The right lobe measures 5.6 x 1.6 x 1.5 cm and the left

lobe measures 4.7 x 1.4 x 1.4 cm. There are bilateral solid

nodules and a nodule along the left isthmus. On the right, 2

solid nodules are present. The larger is more inferiorly located

measuring 2.1 x 1.1 x 1.5 cm and is diffusely hypervascular. The

smaller lesion that is slightly more superiorly measuring 0.9 x

2.7 x 0.6 cm and is not as hypervascular. The left lobe has a

nodule in the upper pole measuring 0.8 x 2.4 x 0.5 cm which is

also diffusely vascular. Smaller nodules are seen in the lower

pole measuring 3 mm each. There is a 1.2 x 0.6 x 1 cm nodule

along the left isthmus, also diffusely vascular.

IMPRESSION: Multiple solid and hypervascular nodules bilaterally.

Correlation with nuclear medicine imaging is recommended, if

clinically indicated.
