Which gland controls sleep/ wake cycles and is thought to have been a “third eye” in our evolutionary past?

Hypothalamus

Pituitary

Pineal

Lacrimal

Considering what we learned about feedback loops, is what we studied about oxytocin’s influence on child birth (uterine contraction) a positive or negative feedback loop?

Positive

Negative

Stop lying to us, Mr. Dalton!

This central nervous system structure helps regulate the pituitary, and even secretes some hormones of it’s own:

Adrenal Gland

Thyroid

Hypothalamus

Atria of the heart

Once you reach adulthood, this gland becomes mostly adipose tissue and still produces some immune cells:

Thalamus

Thymus

Thyroid

Parathyroid

Which of the following is NOT a function of the Endocrine System?

Maintain homeostasis

Regulate overall metabolism

Support, protect, store, and transport substances in the body

Stimulate and facilitate reproductive processes

Which of the following is an example of HOMEOSTASIS? (click all that apply)

Hypothalamus/ Pituitary/ Thyroid Axis' negative feedback loop

Hormonal control of the onset of puberty

Nervous system regulation of heart and breathing rates

Sweating/ shivering to regulate and maintain body temperature

Known as the "master gland" this two-lobed gland releases hormones that control growth and timing process in the body:

Pineal

Pituitary

Pancreas

Thyroid

The parathyroid:

Secretes hormones that control metabolism

Is the large butterfly-shaped gland surrounding the larynx

Secretes insulin and glucagon

Secretes hormones that regulate calcium (Ca⁺) levels

The thymus:

Produces thymosin, which "matures" T-cells in the immune system

Produces T₃ and T₄, both of which act to control metabolism

Secretes hormones that control calcium levels

Does nothing, and isn't worth mentioning

10.

Which hormone does the pancreas secrete in response to a DROP in blood glucose levels?

Insulin

Trypsin

Glucagon

Adrenalin

11.

Adrenalin is produced by which part of the adrenal glands?

Medusa

Medulla

Cortex

Kidney

12.

Other than estrogen, what other hormone is secreted by the ovaries that control secondary female sex characteristics?

Testosterone

Adrenaline

Human Growth Hormone

Progesterone

13.

Some cells in the atria of the heart secrete hormones that:

Increase calcium uptake by the kidney

Decrease digestive processes

Decrease blood pressure (BP)

Increase heart rate

14.

Which is an example of a NEGATIVE feedback loop

Oxytocin release increases uterine contraction, which results in more oxytocin release. This cycle continues until the baby is born.

Fruit are signaled to ripen by the production of ethylene gas by the plant. As they ripen, the fruit begin to produce ethylene gas, which , in turn ripens more fruit, causing the relase of more ethylene gas. Eventually all fruit are ripened.

Blood pressure decreases, which causes the release of aldosterone by the adrenal glands. This hormone causes an increase in sodium levels in the blood. This increase in sodium causes fluid retention. As a result, blood pressure increases, and aldosterone release ceases

Damage to a blood vessel signals platelets to become active. Active platelets release signals to nearby platelets, telling them to become active, and so on.

15.

Think back to our case study on thyroid disorders. What were the hormones involved in the HPT axis we discussed?

TRH and TSH

TRH, TSH and T₃

TSH, T₃, and T₄

TRH, TSH, T₃and T₄

16.

How long is an eon in geology?

1,000 years

100,000 years

1,000,000 years

1,000,000,000 years

17.

How long does it take light to travel from the sun to the earth?

8 milliseconds

8 minutes

8 days

8 weeks

18.

What is a group of giraffes called?

An elevation

A tower

An outlook

An atmosphere

19.

What is a group of lemurs called?

A rumor

A fabrication

A contingency

A conspiracy

20.

Which finger has the fastest-growing nail?

Thumb

Middle Finger

Ring Finger

Pinkie

21.

What do TARGET CELLS have on the cell membranes that allow them to be signaled by specific hormones?

Glands

Receptors

Ribosomes

Homeostasis

22.

Cells that have receptors for specific hormones are referred to as:

Glands

Tissues

Target Cells

Neurotransmitters

23.

In the HPT pathway we discussed, which structure has target cells for TRH?

Thyroid

Pituitary

Hypothalamus

Adrenal Gland

24.

Which structure secretes hormones that help control blood pressure and red blood cell production?

Heart

Small Intestine

Kidney

Stomach

25.

The small intestine has some endocrine function, meaning that it produces hormones that:

Decrease blood pressure

Increase blood pressure

Regulate cell growth

Stimulate hormone release from the pancreas

26.

If there were a tumor on the pituitary that inhibited (decreased) the amount of TSH that was being released by that gland, which of the following would you expect to INCREASE?

Release of T3 and T4

Release of TSH

Release of TRH

Release of melatonin

27.

On which gland would you expect to find a tumor or abnormality if the patient was having issues regulating blood sugar levels and digestive function?

Liver

Adrenal Glands

Pancreas

Pituitary
