Crash Course Endocrine System Part 2 (Case Study)

What symptom prompted Marie to seek medical attention?

• Increased energy

• Weight loss

• Bulging eyes

• Inability to sleep

What is the primary function of the thyroid gland?

• Regulating body's homeostasis

• Strengthening the immune system

• Producing digestive enzymes

• Regulating sleep

What triggers the release of thyroid-stimulating hormone (TSH)?

• Adrenaline

• Thyrotropin-releasing hormone (TRH)

• High blood pressure

• Low body temperature

What is the effect of thyroid hormone on metabolism?

• Slows down digestion

• Reduces body temperature

• Increases ATP production

• Decreases glucose breakdown

What role does the hypothalamus play in the HPT axis?

• It directly stimulates the thyroid gland

• It secretes TSH

• It produces thyroid hormone

• It detects changes in body temperature

How does the body respond to a decrease in external temperature according to the HPT axis?

• By slowing down heart rate

• By decreasing blood pressure

• By increasing glucose breakdown

• By reducing metabolism

How does the body normally regulate the production of thyroid hormones?

• By direct stimulation from the hypothalamus

• Using negative feedback mechanisms

• By increasing TRH levels

• Through positive feedback

What is Graves' disease?

• A genetic disorder affecting the thyroid

• An immune system disorder causing overproduction of thyroid hormones

• A bacterial infection of the thyroid

• An underproduction of thyroid hormones

What causes the eyes to bulge in Graves' disease?

• High blood pressure

• Decreased thyroid hormone production

• Excess calcium

• Inflammation in eye tissues

What is the primary goal of treating Graves' disease?

• To regulate thyroid hormone production

• To stimulate the immune system

• To enhance metabolism

• To increase body temperature
