Below, you will be given four scenarios. Each scenario will describe events that will require or involve endocrine system signaling. For each of these scenarios, answer the following questions:
Choose the primary endocrine gland(s) involved in this scenario. For each, in 2-3 sentences, describe their gross and microscopic anatomical characteristics.
Which hormone(s) released by this gland is involved in this scenario. In 2-3 sentences, describe the stimulus that triggered its release and the associated response to that hormone.
SCENARIO #1:
After a large meal, you eat a huge slice of sugary, chocolate cake. You find yourself full of energy, maybe even a little jittery. Eventually, after a few hours, you crash and begin to feel hungry again.
SCENARIO #2:
You are 13 year old and have reached puberty. You hit a growth spurt and develop secondary sex characteristics, which include changes such as the development of facial hair, breast enlargement, and voice changes. You grow nearly 5 inches over the summer, much to the surprise of your friends and family.
SCENARIO #3:
You are at home alone late at night, and here a HUGE crashing sound in the kitched. Alarmed, you grab the closes heavy object and prepare to fight off an intruder. Your heart races, you breath quickly, you begin sweating, and find yourself experiencing tunnel vision. Thankfully, it was just your cat jumping on the counter.
SCENARIO #4:
Every day, you ask your child to drink one calcium-rich class of milk. Based on everything you’ve hear, you know that milk is important for your child to grow big and strong, due to its positive effect on bone health.
