Hormones Grade 10th Class

Hey there, future health experts! 🌟 Can you help Luna figure out which hormone is secreted by the pancreas to lower blood sugar levels? Is it:

• Cortisol

• Insulin

• Somatostatin

• Glucagon

Hey there, future scientists! 🌟 Imagine you're in a high-stakes game where your body is the ultimate player. Which hormone, like a superhero, swoops in to save the day when stress hits and boosts your blood sugar levels to keep you going? Is it:

• Thyroxine

• Insulin

• Cortisol

• Adrenaline

Hey there, future scientists! Can you help Abigail figure out which hypothalamic hormone is the superhero that triggers TSH release from the anterior pituitary? Is it:

• CRH

• TRH

• GnRH

• GHRH

Answer explanation

TRH, or Thyrotropin-Releasing Hormone, is the hypothalamic hormone that stimulates the anterior pituitary to release TSH (Thyroid-Stimulating Hormone). This is crucial for regulating thyroid function.

Hey there, future scientists! Can you guess which hormone is the superstar behind milk production? Is it:

• Oxytocin

• Prolactin

• FSH

• LH

Answer explanation

Prolactin is the hormone that stimulates milk production in mammals. Oxytocin is involved in milk ejection, while FSH and LH are related to reproductive functions, not milk production.

Hey there, future scientists! Did you know that the adrenal medulla is like the body's own superhero? It has the power to secrete:

• Cortisol

• Aldosterone

• Epinephrine and norepinephrine

• Insulin

Answer explanation

The adrenal medulla is responsible for secreting epinephrine and norepinephrine, which are key hormones in the body's fight-or-flight response. Cortisol and aldosterone are produced by the adrenal cortex, while insulin is secreted by the pancreas.

Hey there, curious minds! Can you help Rohan figure out which gland is responsible for producing the magical hormone melatonin that helps us sleep? Is it:

• Thyroid

• Pituitary

• Pineal

• Pancreas

Answer explanation

The pineal gland is responsible for producing melatonin, a hormone that regulates sleep-wake cycles. The thyroid, pituitary, and pancreas do not produce melatonin.

Hey Aiden, Anika, and Nora! Let's dive into the fascinating world of hormones! Can you guess which part of the body is the superstar when it comes to secreting progesterone?

• Follicle

• Corpus luteum

• Placenta

• Pituitary

Answer explanation

Progesterone is primarily secreted by the corpus luteum, which forms after ovulation. While the follicle produces hormones before ovulation and the placenta secretes progesterone during pregnancy, the corpus luteum is the main source post-ovulation.

Hey there, future scientists! 🌟 Can you help Arjun figure out which hormone is the superhero that increases blood calcium levels? Is it:

• Calcitonin

• Aldosterone

• PTH

• ANP

Answer explanation

PTH, or parathyroid hormone, increases blood calcium levels by stimulating the release of calcium from bones, increasing calcium absorption in the intestines, and promoting calcium reabsorption in the kidneys.

Hey there, future scientists! Imagine you're in a biology class with your friends Michael, Liam, and Daniel. They’re all curious about hormones and their effects. Can you help them out? Low levels of estrogen and progesterone trigger the release of which hormone?

• LH

• FSH

• Oxytocin

• Cortisol

Answer explanation

Low levels of estrogen and progesterone stimulate the anterior pituitary to release FSH (Follicle Stimulating Hormone), which is crucial for ovarian function and follicle development.

Hey there, sleep enthusiasts! If you were to describe melatonin's role in our bodies, which of the following would you choose? Let's see if Benjamin, Ethan, or Kai can guess it right!

• Stimulates ovulation

• Controls blood calcium

• Regulates sleep-wake cycles

• Increases heart rate

Answer explanation

Melatonin primarily regulates sleep-wake cycles by signaling the body when it's time to sleep, making it crucial for maintaining circadian rhythms. The other options do not accurately describe melatonin's main function.
