Endocrine System Things

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

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

• Insulin 
• Trypsin
• Glucagon
• Adrenalin
