Total questions: 35
Worksheet time: 21mins
The maintenance of stable body conditions is called
homeostasis
positive feedback
negative feedback
exocrine function
Hormones travel from an endocrine gland to the target cell by the
circulatory system
respiratory system
nervous system
digestive system
The ____ gland is known as the "master gland" because it influences many other endocrine glands and their functions.
hypothalamus
pancreas
pituitary
thyroid
Yikes! You just ate a big cupcake! What changes would you expect in your body?
Glucose levels in the blood do not change and stored glucose is released from the liver
Glucose levels in the blood rise and glucagon is released
Glucose levels in the blood stay the same
Glucose levels rise and insulin is released
Without the Endocrine System
The body would have a stable rate of metabolism
There would be improved cellular respiration
The body could not maintain homeostasis
Which hormone is produced when the blood glucose concentration is above normal?
insulin
glucagon
both insulin and glucagon
neither insulin nor glucagon
Which hormone is produced when the blood glucose concentration is BELOW normal?
insulin
glucagon
both insulin and glucagon
neither insulin nor glucagon
A person has not eaten for 12 hours. Which hormone is more likely to be produced?
insulin
glucagon
both insulin and glucagon
neither insulin nor glucagon
A person has a disorder when the pancreas does not make enough insulin.
Which form of diabetes is this?
Type I Diabetes
Type II Diabetes
If the environment gets cold, to maintain homeostasis we will often shiver to:
When glucose levels in the blood rise, your brain sends a signal to your pancreas. The pancreas releases insulin, which opens channels in cell membranes to allow glucose to enter the cell, lowering blood sugar levels.
The organ responsible for producing insulin is...
Liver
Heart
Pancreas
Gallbladder
A hormone is
a chemical substance produced by a gland and carried by the lymph.
an enzyme produced by a gland and carried by the blood.
a chemical substance produced by a gland and carried by the blood.
Identify this endocrine gland.
HINT: It is shaped like a "bowtie or butterfly".
Adrenal
Thyroid
Pancreas
Testes
A person has a disorder when the pancreas makes insulin--but the body cells cannot make use of it.
Which form of diabetes is this?
Type I Diabetes
Type II Diabetes
Chemical messengers that cause a response in a target cell are also known as
Phospholipids
Stimuli
Hormones
Receptors
Which of the following is NOT an example of something regulated by the endocrine system?
Blood sugar levels
Water balance
Reproductive cycles
Problem-solving skills
Corrective mechanisms are activated to return a body condition (such as blood sugar) back to its "set point" and then corrective mechanisms are deactivated. This is an example of
Negative feedback
Positive feedback
Neurotransmitter regulation
Action potential
Which of the following is NOT a function of the endocrine system?
Endocrine glands release hormones into the bloodstream
Regulation of body processes such as metabolism
maintenence of homeostasis
transmit electrical signals between the nervous system and the body
Which of the following best describes how a hormone matches with its target cell?
Hormones fit with a specific receptor based on shape
Some target cells are hydrophobic and others are hydrophilic
It depends if the hormone is secreted into the blood or a duct
It depends on the type of epithelial tissue that surrounds it.
Which of the following is NOT part of the endocrine system?
SELECT ALL THAT APPLY
Pituitary
Appendix
Thyroid
Pineal
Prostate
Where are the major endocrine glands located?
SELECT ALL THAT APPLY
Brain
Neck
Shoulders
Abdomen
Groin
Which of the following acts as the "third eye" by responding to light exposure and regulating the circadian rhythms of the sleep/wake cycle?
Pituitary
Pineal
Hypothalmus
Thyroid
Which of the following is a hormone released to regulate the circadian rhythm of the sleep/wake cycle?
Thyroxine
Melatonin
Glucagon
Calcitonin
What is most likely to happen if the endocrine system fails to function properly?
A change in the function of DNA
A change in the method of cellular respiration
A disturbance in homeostasis
A stable rate of metabolism
Where can the receptors for insulin be found?
On the surface of liver cells only.
On the surface of body cells only.
On the surface of body cells and liver cells.
On the surface of blood cells only.
Which endocrine gland helps regulate the body temperature (like a thermostat)?
Thyroid gland
Hypothalmus
Lungs
Brainstem
Which of the following is a disorder of the endocrine system?
Mental Illness
Alzheimer's disease
