1. 14A high level of blood glucose triggers ______(hormone) release from the ______(gland). This hormone promotes the uptake of ______ and the synthesis of _______.A low level of blood glucose triggers_____(hormone) release from the ______(gland). This hormone promotes the production of _____ via the breakdown of ______.Homeostasis level of blood glucose is ______/_____

A high level of blood glucose triggers cortisol release from the pancreas. Cortisol promotes the uptake of glucose and the synthesis of glycogen. A low level of blood glucose triggers adrenaline release from the pancreas. Adrenaline promotes the production of glucose via the breakdown of glycogen. Homeostasis level of blood glucose is 95mg/100mL.

A high level of blood glucose triggers insulin release from the pancreas. Insulin promotes the uptake of glucose and the synthesis of glycogen.
A low level of blood glucose triggers glucagon release from the pancreas. Glucagon promotes the production of glucose via the breakdown of glycogen.
Homeostasis level of blood glucose is 90mg/100mL

A high level of blood glucose triggers glucagon release from the liver. Glucagon promotes the uptake of glucose and the synthesis of glycogen. A low level of blood glucose triggers insulin release from the liver. Insulin promotes the production of glucose via the breakdown of glycogen. Homeostasis level of blood glucose is 100mg/100mL.

A high level of blood glucose triggers insulin release from the liver. Insulin promotes the uptake of glucose and the synthesis of glycogen. A low level of blood glucose triggers glucagon release from the liver. Glucagon promotes the production of glucose via the breakdown of glycogen. Homeostasis level of blood glucose is 110mg/100mL.

2. In pancreas, which cells make glucagon when there is low blood sugar?

In pancreas, Alpha cells make glucagon (low blood sugar)

Gamma cells

Delta cells

Beta cells

In the pancreas, alpha cells are responsible for producing glucagon in response to low blood sugar levels. Beta cells produce insulin, delta cells produce somatostatin, and gamma cells are not involved in glucagon production.

Explanation

In the pancreas, alpha cells are responsible for producing glucagon in response to low blood sugar levels. Beta cells produce insulin, delta cells produce somatostatin, and gamma cells are not involved in glucagon production.

3. 14and _____ cells make insulin (when there is (low/high) blood sugar. _______ goes to the liver to make more glucose.

Delta

Omega

Alpha

And Beta cells make insulin (high blood sugar). Glucagon goes to the liver to make more glucose

Beta cells are responsible for producing insulin when blood sugar is high, while glucagon stimulates the liver to release stored glucose when blood sugar is low.

Explanation

Beta cells are responsible for producing insulin when blood sugar is high, while glucagon stimulates the liver to release stored glucose when blood sugar is low.

4. Where does Glucagon go to stimulate the production of more glucose?

Muscles

Brain

Glucagon goes to the liver to make more glucose

Pancreas

Glucagon is a hormone that acts on the liver to release stored glucose into the bloodstream, providing energy for the body.

Explanation

Glucagon is a hormone that acts on the liver to release stored glucose into the bloodstream, providing energy for the body.

5. 15A high level of blood calcium triggers ______ release from the ______ gland. This hormone function is to ______

Parathyroid hormone release from the pancreas. Parathyroid hormone promotes the absorption of calcium from the bones into the bloodstream

Estrogen release from the pituitary gland. Estrogen plays a role in the development of female sexual characteristics and reproductive functions

Insulin release from the adrenal gland. Insulin regulates blood sugar levels by promoting glucose uptake into cells

Ahigh level of blood calcium triggers calcitonin release from the thyroid. Calcitoninpromotes the excretion of calcium and its deposition into bone

The correct answer is calcitonin release from the thyroid. Calcitonin helps regulate blood calcium levels by promoting calcium excretion and deposition into bone. The other options provide incorrect information about hormone release and their functions.

Explanation

The correct answer is calcitonin release from the thyroid. Calcitonin helps regulate blood calcium levels by promoting calcium excretion and deposition into bone. The other options provide incorrect information about hormone release and their functions.

6. A low level of blood calcium triggers ______ release from the ______. This hormone promotes ______

Alow level of blood calcium triggers PTH release from the parathyroid. PTHpromotes the retention of calcium by the kidney and the release of calcium frombone.

A low level of blood calcium triggers ADH release from the adrenal glands. ADH promotes water retention in the kidneys.

A low level of blood calcium triggers GH release from the pancreas. GH promotes the breakdown of fats.

A low level of blood calcium triggers ACTH release from the thyroid. ACTH promotes the production of cortisol.

The correct answer involves the parathyroid gland and the hormone PTH, which plays a crucial role in regulating calcium levels in the body.

Explanation

The correct answer involves the parathyroid gland and the hormone PTH, which plays a crucial role in regulating calcium levels in the body.

7. Where are hypothalamic neurohormones stored and released from, directly into the general circulatory system?

These hormones are stored in and released from the posterior pituitary, or neurohypophysis, directly into the general circulatory system
The anterior pituitary makes enodocrine hormones

The adrenal medulla

The anterior pituitary

The thyroid gland

Hypothalamic neurohormones are stored in and released from the posterior pituitary, also known as the neurohypophysis, directly into the general circulatory system. This is an important aspect of the endocrine system's regulation of various bodily functions.

Explanation

Hypothalamic neurohormones are stored in and released from the posterior pituitary, also known as the neurohypophysis, directly into the general circulatory system. This is an important aspect of the endocrine system's regulation of various bodily functions.

8. 17Anterior Pituitary (AKA _____)

Anterior Pituitary (Neurohypophysis)

AnteriorPituitary (Adenohypohysis)

Anterior Pituitary (Thyroid)

Anterior Pituitary (Hypothalamus)

The Anterior Pituitary is also known as Adenohypohysis, whereas the incorrect answers do not correspond to the correct term.

Explanation

The Anterior Pituitary is also known as Adenohypohysis, whereas the incorrect answers do not correspond to the correct term.

9. What hormones have both tropic and non-tropic effects?

Non-tropic hormones

Tropic hormones

Steroid hormones

Thyroid hormones

Tropic hormones have the ability to exert both tropic effects on target organs to stimulate other endocrine glands and non-tropic effects on non-endocrine tissues.

Explanation

Tropic hormones have the ability to exert both tropic effects on target organs to stimulate other endocrine glands and non-tropic effects on non-endocrine tissues.

10. The hypothalamic hormones are secreted into the blood and travel through a short circulatory vessel (the portal vessel) directly to the __________ AKA ______.

Posterior pituitary or neurohypophysis

Thyroid gland or thyroid stimulating gland

The hypothalamic hormones are secreted into the blood and travel through a short circulatory vessel (the portal vessel) directly to the anterior pituitary or adenohypophysis.Here the tropic hormones regulate the release of other hormones from the pituitary into the general circulation. Some pituitary hormones are also tropic hormones

Adrenal medulla or adrenal cortex

The hypothalamic hormones travel to the anterior pituitary or adenohypophysis to regulate the release of other hormones into the general circulation.

Explanation

The hypothalamic hormones travel to the anterior pituitary or adenohypophysis to regulate the release of other hormones into the general circulation.
