Homeostasis

Which part of the brain controls body temperature

• medulla oblongata

• cerebrum

• corpus callosum

• hypothalamus

When you are hot, your body sweats to cool you down. This means your temperature went above normal and your body sweats to counteract that change to bring you back to normal. What kind of feedback loop would this be?

• Negative Feedback Loop

• Positive Feedback Loop

• Neutral Feedback Loop

• Linear Feedback Loop

Homeostasis

• allows for a wildly fluctuating internal environment
• is impossible in vertebrates
• is the maintenance of a relatively stable internal environment and often incorporates a form of feedback regulation

• panting and vasoconstriction

• sweating and piloerection

• sweating and vasodilation

Blood sugars are controlled by

• brain generated chemicals

• blood

• hormones from the pancreas

• chemicals from the liver

The hormone that makes the liver store sugars is

• glucose

• glycogen

• glucagon

• insulin

The liver normally stores blood sugar as

• glucose

• glycogen

• glucagon

• fats

The cells in the brain which monitor blood sugar levels are the

• glucoreceptors

• granulocytes

• homeocytes

• sucrocytes

High blood sugar levels after a meal usually stimulate

• Glucagon release from the liver

• Glucagon release from the pancreas

• Insulin release from the liver

• Insulin release from the pancreas
