What are the two most important hormones for regulating blood glucose?

1. Insulin 2. Glucagon

What is the main hormone release in response to hypoglycemia? Where is it released from?

-Glucagon -The alpha cells of the Islets of Langerhans in the pancreas

When is insulin secreted and from where?

When blood glucose levels increase it is secreted from the beta cells of the pancrea's Islets of Langerhans

What are the two ways glucagon raises blood glucose?

1. Hepatic glycogenolysis (breakdown of glycogen to glucose in the liver) 2. Gluconeogenesis (Creation of glucose from non-carbohydrates)

What are the five ways insulin lowers blood glucose?

1. Diffusion of glucose into cells 2. Active transport of amino acids into cells 3. Glycogenesis 4. Protein synthesis in cells 5. Lipogenesis (triglyceride synthesis)

What produces GH? What hormones govern it's release and where do they come from?

-the anterior pituitary -GHRH and GHIH from the hypothalamus

Low blood glucose stimulates the release of GHRH or GHIH? High blood glucose stimulates the release of GHRH or GHIH?

-GHRH -GHIH

GH contributes to glucose metabolism by (3): It's overall effect of GH is to ______ blood glucose

-Increase 1. Helping to stimulate glycogenolysis 2. Stimulating lipolysis 3. Metabolic effects like stimulating protein synthesis

Where is cortisol produced? What stimulates it's production?

-The adrenal cortex -ACTH (Adrenocorticotropic hormone)

What are cortisols three main functions regarding glucose regulation? It's over all effect is to _____ blood glucose

-Increase 1. Promotes protein catabolism 2. Promotes lipolysis 3. Promotes gluconeogenesis

Where is thyroxine produced? How does it contribute to glucose regulation (2)? It's overall effect is to ________ blood glucose

-Thyroid 1. Increases glycolysis 2. Increases lipolysis -maintain

What are the two catecholamines?

Epinephrine and Norepinephrine

Where are the catecholamines produced? What are the two ways affect blood glucose? It's overall effect is to _______ blood glucose

-Adrenal Medulla 1. Promotes glycogenolysis 2. Promotes lipolysis -increases

During hormonal regulation in the absorptive (fed) state insulin is involved in decreasing glucose in it's 5 ways, what two other hormones work during this state and in what way?

-Thyroxine and GH are involved in protein synthesis during the absorptive (fed) state

In the post absorptive (_____) state what two hormones are involved in glycogenolysis? Where does this occur?

-fasting -Glucagon and epinephrine -muscle fibers and hepatocytes

In the post absorptive (fasting) state what five hormones are involved in promoting lipolysis? Where does this occur?

1. Epinephrine 2. Norepinephrine 3. Cortisol 4. GH 5. Thyroxine -Adipose cells

In the post absorptive (fasting) state what hormone is involved in promoting protein breakdown? Where does this occur?

-Cortisol -Most body cells (especially skeletal muscles)

In the post absorptive (fasting) state what two hormones are involved in promoting gluconeogenesis? Where does this occur?

1. Glucagon 2. Cortisol -Hepatocytes (and kidney cortex cells during starvation)

During a period of hyperglycemia protein _______ is promoted by the hormones ______, ______ and ____ _______ to help lower blood glucose

-synthesis -insulin, thyroxine and growth hormone

During a period of hypoglycemia protein _______ is promoted by the hormone ______ to help raise blood glucose

-catabolism (breakdown) -cortisol
